New Lampizator Level 4/ Version 4 DAC in the house


Wonder if any other new owners of this DAC are out there as I find it to be the finest digital playback I have heard to date. This is the first digital front end piece of gear I have owned that has transformed my music.

Ya, other digital gear does this or that better, but this Lampy breaks through to a new level of musical enjoyment. Clear view into the music helping the speakers just disappear. Only 24 hours of break in and the music flows so sweet, intimate and seemingly without boundaries.

Looking under the hood I see an impressive power supply with films caps and several high quality chokes. Point to point silver wired except for the digital and USB boards. This is a three tube player that is tube rectified. One has the option for SS rectification if desired.

Ya, I love this Lampy!

Bill, Tony is correct. Middleware. There is a little redundancy in your planned experiment although it would be interesting to hear the comparison. I am sure it can be arranged....:)

Tony have you heard the new Lessloss Laminar streamer? An audio buddy heard a prototype in California and was impressed. Lessloss thinking regarding digital has always made sense to me....
Andrew, I heard the Laminar streamer in it's infancy about 3 years ago at RMAF. It certainly has some promise, and I thought it sounded good going through a DAC 2004. However, I fear it will be grossly overpriced given the technology used. In fact at this point I am still not certain it is a finished product. I think they had one at the NY show recently and had it covered up.

I have been using a Lessloss DAC for 6 years now and find it is still hard to beat. Multi-bit DAC chips (alas nearly all are 1-bit now) and direct coupled at the output, as well as battery power on the output stage. It is well designed. Their concept of mating it with a CEC TL-51X in order to use the 256f clock output of the DAC to slave the CEC to it made a lot of sense.

With the Laminar they are taking the approach that the clock in the streamer is more important. Personally I think it's a marketing move as the DAC 2004 is no longer manufactured and they want sell streamers for use with any DAC. I believe there is also some debate about other aspects of the design and saw some comments Gordon Rankin made regarding the design approach.

In my current configuration my DAC is slaved to the clocks in the Audiophilleo USB converter that I use. While I think the sound is very good. I still wonder what I might gain if I can find a middleware solution that would allow me to slave it to the DAC. The solutions I have encountered so far use a PLL which is not necessarily optimal but gets the job done.

Keep an eye on SOtM. They were at CES and I heard their sever/DAC in the ESS Labs room. Very good and well built. I think over time they will be a leader in computer audio.
In looking over some things I find myself revisiting Gordon Rankin's Crimson and Cosecant USB DAC designs. Some nice work from one of the pioneers of computer audio.
Getting back to the subject of LampizatOr, I am not sure the buffer size used by the Squeezebox driven TranspOrt. Its never been an issue with a wired or even wireless connection in my experience, but I will do some digging in case people with latency issues in their home networks have questions.

In the meantime, perhaps starting another thread for miscellaneous topics is appropriate? There is some good information getting buried in the off topic conversation.

It's a performance issue and not just latency. All computer buffers to enhance performance.

Bryston BDP, Audirvana, JRiver ... they all buffers at least 1st track before play. If you ask Lukasz about buffering he will understand. I'm interested how much his transport buffers before play.
+1 with brand new Lampizator L4 G4

Dear Users,
Do you have any experience with Lampizator USB board? How does is cooperate with Mac Mini? Or is it better to use usb-> spdif converter ?

Thank you for you help
I visited the Lampizator suite every day. By Friday I was very impressed with the L7's character, but I didn't like the overall sound. I thought the room was way too small and the speakers questionable. I had never really paid much attention to the various Lampizator models, but I think I prefer the L7.

It was only after I heard high hat on it that I was satisfied that it was full range. I am hoping to get a better listen to it in my system.

I seem to have very dissimilar tastes to many here. With quad dsd on the horizon and double dsd now available, I don't think vinyl as normally heard is the standard anymore. Sony is going to put all of its master tapes on quad dsd. This represents about forty percent of the master tapes in the world. Digital in this form will soon be the standard. I have heard double dsd and it is really real sounding. I can only imagine what quad dsd will sound like.

I must say that quad dsd is going to require new dac chips and solutions on how to get it to the dac from the drive.
KingHifi.

The buffering would be in the domain of the Squeezplay software engine on the host computer, similar to Audirvana/JRiver and that info is in the public Domain. The SBR is just the streamer/Dac and the Lampizator treatement paradigm is to discard the feeble Dac function and to enhance the digital pass thru by reclocing, improving components and Power supply, as well as to square up the digital wave via the use of the digilampizator.

The TranspOrt is NOT the same as the USB/SPdif converter...there seems to be some confusion here.

Tbg, hello, long time no speak. The speakers were not properly set up and broken in until late Friday, i am told...then it started impressing mightily. Previous skeptics have broken out their checkbooks, I am told. Finally, I have a Lampi DSD-only dac and I can attest to the fact that properly recorded 128 stuff is sublime!
From Lampizator Transport web page:
"MY LampizatOr Transport plays from own FIFO RAM Buffer."

This is the buffer I'm asking? Does it buffer X amount or number of tracks before play starts.

Without going into too much detail, I was just using JRiver, Audirvana ... as examples.
Some props from Audiofederation who has historically been a demanding listener who has angered many an industry type: http://audiofederation.com/blog/categories/shows/ces-2014/
Kng, You are correct (I was wrong, mea culpa). While there may be local computer "buffer" its not that critical as the signal still has a ways to go to hit the Dac.

After investigations, there IS indeed a Ram buffer located in the SB-R, similar to buffers in DVD players. The buffer is very fast RAM memory and is located an inch or so away from the tube output, so a TRUE buffer, for about 4 seconds (I believe). This is the basic architecture of the SB-R and not unique to the TranspOrt.

The Squeezecentre player may also be storing info on the computer before sending via wireless or LAN cable, but would not be a true buffer, as much can happen to screw up the signal before it gets to the Dac, given the USB cable transmission and the stock SBR processing.
Wisnon, Computers have been using buffers/cache forever to improve performance. This is true in both hardware and software.

From Lamp Web Site:
Once again - how can a "stupid" computer modem sound better than reputable real CD transport ? Computers are supposed to be BAD.
I will try to explain how I see it:

Just imagine: It thakes 70 minutes for the Philips CDM2-Pro mechanism to read all data from CD disk. The same amount of data is read by DVD drive in 2 minutes. Blue Ray reads it in half minute. Hard drive reads it in 4 seconds. RAM buffer reads it in less than a second. MY LampizatOr Transport plays from own FIFO RAM Buffer.

The Data from CD must be read by a laser, which constantly needs to adjust focus, servo adjusts linear speed of motor, and track tracking. The data is demodulated from laser waves, and missing bits or errors are interpolated and corrected. Vibrations make reading difficult.

The HDD Lampizator Transport player needs nothing of that. Perfect, 100% accurate data is fed to RAM buffer and just (FIFO) - sent out to DAC according to external precision clock.
This scenario is 100 x more simple, errofr free and accurate. I am surprized that CD players play anything at all ;-)
This is what I've been saying for years but Lukaz has the numbers to support it.

"Perfect, 100% accurate data is fed to RAM buffer and just (FIFO) - sent out to DAC according to external precision clock."

Lukaz recognizes the benefits processing from RAM so just can't imagine there is no mod to the stock SB FIFO RAM buffer.
It looks like the Lamp had a volume control, was it ever run direct to his amps?
Abruce, the did run it direct for a while and it apparently sounded very good that way. What is your preference? I will try both.

Dale needs to learn how to smile: http://www.stereophile.com/content/lampizator-and-mosaic
That's too bad was hoping to find out if the Dude helped the sound or was the Lamizator great on its own
Abruce, yes it was because the Dude preamp needed breakin.
Speaker is new, Dude is new ... that's what I called excellent show preparation. So what was broken in, component rack? LOL!
Knghifi, the reality is that almost everything at CES or any show is new. That is why at Friday through Sunday shows, you really should just show up on Sunday.

Well said. Spoken by someone who understands the process from experience....
Abruce, time for me to come over with my Dude again and instead of a preamp shoot out perhaps we now compare to the Lampy volume control?
Sounds like a plan Grannyring
Let me know what works for you, to add more confusion dont forget the Offramp
Wh os tyhe lucky guy that bought the L7 cash from the Show?

Would love to hear feedback from him/her!

The Hong Kong feedback has been gushing so far...
Abruce's, I just got the Dynamo power supply for the Offramp.......oh my! My Lampi never sounded this good! Trust me when I say the Offramp and Dynamo power supply will not confuse anything....you will know in a nano second how they improve the sound of your system. A nano second.

Feed the Lampi the best signal you can and your ears will be delighted!
Feed the Lampi the best signal you can and your ears will be delighted!

That is why Lucas has created his own transports. It would be Interesting to compare the offramp and the USB converter from Lampi with all its flawed tube engineering....;)
Agear, I would agree with you in that I would like to compare. The Offramp and Dynamo together jumped the performance of my Lampi and digital front end at least 50%.

The DAC is important, very important, but what it is fed is perhaps more important. I will make a bold statement here. I bet my Lampi 4/4 with the Offramp/Dynamo sounds better than a Lampi 5,6 or 7 with no Lampi or Offramp transport.

What I am trying to say is, if you own a Lampi dac and do not use an Offramp or Lampi interface, then you have not really heard that dac! At least you have not heard it's full cababilities. This is based on using the USB input from any computer source...and I mean any computer brand or type.
This is what I say on every forum. The jitter of the digital source is MORE IMPORTANT than the DAC. It's true. And Empirical Audio has been developing lower and lower jitter products for more than 15 years.

You must understand what jitter is and how it should be measured if you want to make intelligent decisions. A single RMS or even peak-to-peak jitter number is grossly insufficient. If you purchase gear based on such specs, you are making a gross error. The first flag that everyone should raise with a product is if they claim to eliminate jitter or have zero jitter. Impossible.

Jitter occurs as a Gaussian distribution of cycle-times. If you only publish one number, you don't know the shape of the Gaussian curve. It could be wide a flat or narrow and tall and still have the same RMS jitter number. The "tails" of the jitter distribution are also important. If these P-P maximums only occur every 20-30 seconds, this is totally inaudible. At Empirical Audio, we measure the jitter distribution in a histogram. We have found that narrow and tall distributions sound much better than wider, shorter distributions, even if the majority of the jitter is in the 50psec range. This makes perfect sense, since the jitter of a thin distribution is bunched in a tight range and not varying widely on average.

Shawbros might argue with you but I believe it. Dynamo means non-chinese walwart ps?

The DAC is important, very important, but what it is fed is perhaps more important. I will make a bold statement here. I bet my Lampi 4/4 with the Offramp/Dynamo sounds better than a Lampi 5,6 or 7 with no Lampi or Offramp transport.

I am glad you have finally been converted. I made that same statement earlier in the thread and you actually argued with me. Your modded mini was king at the time.:)
This is what I say on every forum. The jitter of the digital source is MORE IMPORTANT than the DAC. It's true. And Empirical Audio has been developing lower and lower jitter products for more than 15 years.

One could argue that any dac worth its salt should be able to process jitter much like old school engineer types who say that any well designed power supply should not need power conditioning.

Steve, the Ifi crew claims lower jitter specs than Offramp at a fraction of the cost (http://www.digitalaudioreview.net/2013/04/amr-ifi-announce-ilink-usb-spdif-converter/). Any comments?

Transports and jitter busters aside, you can not turn the chinese dac du jour into a Lampizator 7 with jitter management....:)
"Steve, the Ifi crew claims lower jitter specs than Offramp at a fraction of the cost (www.digitalaudioreview). Any comments?"

I don't know where they get this. Send me an iFi and i'll publish the jitter distributions of OR5 and iFi.

In the end what matters is how the device sounds when connected to a DAC, not how it measures when connected to a test system anyway.

I don't see any iFi things taking best of show at Newport or RMAF. They have their pricepoint and I have mine.

Grannyring,

If you buy a modded DVD player from the Lampi shop of just buy the digi-Lampizator kit 100euros and add to say a Denon DVD3910, you get astounding performance. Myself, I have just the Spdif modded Denon (no digi mod) and i disabled all the video sections, etc. Best spinner I have.

I also use a stock Duet with upograded caps and deicated LPSU and that is great.

Point is jitter is only half the story. Power (waveform distortion) is the other.
I think its too much to say low jitter is the end all and be all of good sound. Its important, yes, but not all.

Many ways to skin a cat.
Agear, the wallwart on the unit was actually much better than a standard wart as Steve does use/make a good one. The separate Dynamo power supply is much, much better however.

I don't know the science as well as I should regarding jitter, waveform distortion and the like, but boy is my rig smoking good after these last additions!
Wisnon, I have owned some great modified transports and compared to my current computer based front end they sounded average......knowing what I hear now. I will never go back to a spinning disc. I would loose so much. I use the Amarra built in EQ to assure a flat room response. I would loose that. This tool is awesome! I would loose the ability to improve the sound by converting files to WAV and WAV 24/88.

My digital front end, based on my experience, is far superior to any spinning CD transport I have yet encountered. The Lampi, Apple Mac mini, Amarra, Offramp/Dynamo combo is just heaven to my ears. Ya, it costs lots more than your example for sure, so it better sound good.

If I ever need a spinner your option sounds like a great, lower cost one. It does sound interesting.
Sorry for the spelling ......meant lose not loose.

My Lampi dac has Jensen caps and I am close to trying some Duelund CAST caps. Not sure if this is the way to go or not. Has anyone compared both caps in the same Lampi unit?

The Jensen caps are rich, full bodied and so smooth with a touch of warmth. The Duelunds will be more resolving, but I wonder if I will loose the warmth?
You can get close to the Duelands with ~3uFd oil caps combined with .22uFd CUTF caps from v-cap.com. I think the non-CAST Duelands would be sufficient. The CAST are best in speaker crossovers.

Hi Bill, I'm pretty familiar with the Jensens and you have described them accurately...they are a "feel good" cap that will make most systems lean to the 'pleasant' side of real. They are very seductive in that regard and even in a generally well balanced [referring to tonal character] system they are difficult to remove once you are accustomed to their sound. I would also recommend them to anyone with a slightly "hot" or "etched" system...perhaps someone with NO tubes anywhere through the signal path and that might lean to a traditional ss sound...these will be ideal.
As for the Duelund cast caps, not only are they more resolving (a good thing) they are also less warm (but still a GOOD thing) because what they REALLY are is utterly natural and realistic sounding.
In my experience I have heard the Lampi L4G4 with Jensens in my system and instantly heard its obvious appeal. Once I almost immediately caught the Lampizator Dac bug I decided to move up and everything I read and heard about the "Big 6" convinced me it was a perfect choice, so I ordered one. As it turned out due to a temporary backlog of Duelunds, I went with the VH V-caps in it and learned about their particular character too. Can you say: Detail, transparency, dynamics...did I mention Detail? They were quite a contrast to the Jensens and I'm sure that in a more 'traditional' and perhaps tube-rich system they would be welcomed with their strengths. But the Duelunds finally arrived and went right in.
Here is what I'll say about the Duelunds (and please remember both my TRL Dude AND TRL GT-200 monos are fitted with them too); "Reality has landed..." Take whatever you liked about the Jensens, whatever I liked about the V-caps, whatever anyone may find as a positive attribute about any of their favorites and distill them all into a perfect blend. What you'll get is what REAL sounds like. That's what they sound like. Real. No excess... no 'lean towards...' No distinguishing flavor... Just real, honest, truthful, natural music as if it was there...or, I should say: as if it was "Here, in your own room".
IMHO do not hesitate to go with the Duelund cast copper caps wherever you can. (Yes, fortunately / unfortunately, whichever way you vs your wallet may see it), their effect IS cumulative with each piece of gear in the food chain.
Remind yourself how seriously better some piece of new equipment really made you feel? I mean a real, significant and obvious advancement in bringing you 'closer to the real thing'..in YOUR own room?
Do the Duelund(s). You'll feel it again.
My personal two cents. Keep in mind they do need quite a few hours before sounding their best but still sound darn good with barely a hundred. Be patient on up to 400 or more before they're finally at their best and don't be too surprised when a few months go by and you still note subtle aspects of better-than-ever...
Good luck with it and Happy Lissn'n!
Lissnr, I also have CAST in my Dude and have put them in all kinds of gear and know the sound well. I was wondering about specific placement in the Lampi dac as my music is so darn good right now and wonder if the CAST would tilt my system over to the analytic side of things.

Your comments help me for sure. I will say I put the CAST in my past amps, CD player and had them in my Dude and things got too detailed and lean for my liking. So for me too much CAST is possible it seems, thus my hesitancy. My current system is not bright or lean in the slightest way. If anything it may be on the warm and romantic side.

I have Coincident TV III speakers which are pretty neutral and perhaps a tad warm. My Thor TPA el34 amps are warm and have Audio Note copper caps. My Lampi dac with the Jensens sounds exactly like you outlined above. You know how our Dudes sound with the CAST......full of piss and vinegar! Ha! Bold, big, dynamic and real! I would not call the Dude warm, but let's everything through as intended.

Wish I had your amps! You have the finest amps available and are blessed indeed.

I am going to go ahead and try them in my Lampi.
Steve, I bet your comments on the PIO caps bypassed with Vcaps is accurate. I have to admit I have a place in my heart for Duelund. They can be very, very special in the right gear. The Lampi may well be the right gear!
Knghifi, the reality is that almost everything at CES or any show is new. That is why at Friday through Sunday shows, you really should just show up on Sunday.
If this is reality and believe in break in period, why bother showcasing your system if they are not at its best? It could do more harm than good when 1st impression is crucial. What do you do before selling a car or house?

Components take time to settle plus fine tuning so usually sounds best on the last day from my experience.
Hi Bill, I understand your hesitancy when it comes to losing the beauty of the Jensen's warmth but it sounds like you have some warmth to spare considering the EL-34's in the Thor (I love that tube, its been my long term favorite output tube for almost 20 years)... add in the Audio Note coppers and it makes me think there should be room to swing back a little 'true-er'.
After all my above assertions I agree that the Duelunds will bring you closer to the real thing and I am reinforcing that but I also want to remind you that, based on your equipment it's obvious that you (understandably ) enjoy a bit of warmth in your system.
I still have one of the amps I used before the TRL's (thank you for your compliment) which is my Cary SA 280 V12R that also uses the Jensens and EL-34's.So believe me when I mention that not only is it OK to linger on the warmish side...I've lived there myself with thousands of hours of musical enjoyment and the only criticism (too strong a word but I'm making a point) is that it did veer from the truth. But, after
thousands of hours I can easily say: "so what?".
Point is, yes, you will get a considerably more truthful presentation and you will be very impressed...you will truly enjoy its candor and its lack of accent flavorings and you will know right away it's more of what the truth is. But, if you are anything like me (sentimental but usually reluctant to admit it) you will not/should never sell the Jensens because in your mind you will have to know that IF you ever wanted to 'go back', even for a brief visit...you could always pop them back in and reminisce about the old days.
Good luck, enjoy. Report back!
Grannyring,

I'm happy that the Offramp/Dynamo combination is working so well for you. Like I said before it doesn't surprise me at all, I've heard only great things about Empirical Audio gear and their effectiveness in reducing jitter.

I am a bit surprised though that you state there is a night and day difference between the two inputs. My friend that bought my L4/G4 (just like yours with Jensens)hooked it up via SPDIF through the Empirical Offramp4 and though he said it sounded better than his Mojo Audio DAC, he expected much more. He then tried the USB input from his modded Mac Mini and finally heard the Lamp magic. It could be that the Offramp 5 is an entirely different beast than the O4, I don't know, but I was making that comparison so that folks know that the USB input can be VERY rewarding for sure.

In my case, I have never used a SPDIF converter. The O5 all dressed up could cost near $3k+, so I chose to go a different route and use the extra $$$$ to reduce jitter from the computer's USB port and provide clean power to the server. I think the 2010 Mac Mini is a very noisy server compared to a Windows 8 CAPs server (IMO), but it has a very BIG and warm sound so it might fit better in some systems. The Windows 2012 PC server I'm using right now sounds pretty darn good. It makes the Mac Mini sound veiled and colored. I've never had a 2009 Mac Mini/O5/Dynamo in my system and am curious to know how it would stack up against my server. I'll have to borrow an O5/Dynamo someday to kill my curiosity but for now the USB input on my Lamp does my music justice.

Regarding the Jensens vs Duelands. With vocals, the nod goes to the Jensens, there's just a sweetness to them that really gets to me. But overall, the Duelands are better especially with complex music. The Jensens just fall apart, like a 45 tube trying to power inefficient speakers. The Duelands don't smear and can delineate instruments with uncanny ability. Resolution is amazing as well. You will not get the warmth of the Jensens, but as Lissnr put it, the Duelands just sounds REAL.

Have you ever tried a Windows based PC before in your system?

Happy Listening!
Knghifi, yours is a very good question. Most of the answer, I think, centers on not being organized. Many, especially small, manufacturers don't have stock to devote to prepare for the shows, including, of course, break in. Certainly TAD is one clear exception. They may seek better rooms and may fine tune their systems, but I have not heard much difference from day one onward.

But I should add that the use of hotel rooms is another major problem. Most are pretty awful. CES's putting the high end audio in the Venetian Towers means that many have two level room where there is no proper best listening placement. The railing of the higher portion is where you should be sitting.
Hi Lissnr,
You description of the Duelund CAST is simply dead on the bullseye. Very well said and fits my experience with them. The key words are natural and real, acoustic instruments have inherent warmth, body, color and vibrancy and they don't require any embellishment. The CAST have superb resolution and transparency yet aren't remotely analytical or clinical, just"organic" and correct. I'm actually surprised Bill experienced too much detail in some applications (perhaps revealing the character of ofter system components? ). I don't know, I can say that using the CAST in my DAC and speakers has provided stunningly excellent music reproduction and heighten the sense of realism. The Jensen may yield a pleasing "added" warmth but the Duelund are the "natural" choice.
Charles,
This is not a problem just buy two dueland caps and replace the jensen with them. If you don't like them you can always place the jensens back. In the lampizator this is a very easy job. Now get to it and report back.
Jwm, will do!

Shawbros3, my mini is a 2009 with many mods including an outboard power supply ....... Not using the switching wall wart. My Offramp 4 is loaded with Turbo clocks, Hynes Reg, latest transformer .......

The fact is the Dynamo power supply improved the sound more than the Offramp by itself. The Offramp alone was a nice improvement, but the Dynamo power supply was epic. I have shared that with Steve.

Next on my list will be placing Duelund caps in the Lampi!

I also use EA's spdif cable which is killer and should be used with the Offramp. I also use a USB filter made by UltraFi. It does a great job cleaning things up before the Offramp. Go to the UltraFi page and see it. It is called the Aubisque filter. Others make these sort of small USB filters. A/b testing proved this little device works well.

I am sure other means to sonic bliss abound and share what I have found with my Lampi and computer set up.

I am also sure the music player used....Amarra etc, also plays a big role. I think Amarra is the best option with it's room correction EQ tool. So many things impact the sound of a computer based front end. Some systems are more resolving than others making it easier to hear differences. All the little things in the end make a big difference in computer based audio. Which USB port used on the Mini matters, turning off programs in the Mini matters, software mods on the operating system matter. If these things are not done, then the Mini in question my be a jitter nerd:-). Love that phrase!
"If this is reality and believe in break in period, why bother showcasing your system if they are not at its best?"

Well, the show managers will not let us in but one day before the shows and this is simply not enough for break-in. Barely enough time for good setup. BTW, it's not just new components. I have exhibited at maybe 16 shows and each time the equipment needs break-in, even equipment that has had years of break-in. This effect I believe is due to static charge developing on all of the dielectrics during shipping and setup. Sunday is always the best day and it will probably always be that way.

"hooked it up via SPDIF through the Empirical Offramp4 and though he said it sounded better than his Mojo Audio DAC, he expected much more."

There are improvements in the OR5, but there are also updates to the OR4 that make it a LOT better. Those that lose touch by not visiting my forum regularly lose out on these updates. Most are very inexpensive.

"Certainly TAD is one clear exception. They may seek better rooms and may fine tune their systems, but I have not heard much difference from day one onward."

I had TAD E1's in my room 2 years ago at Newport show. They claimed they were broken-in. They weren't. Took 2-3 days before they opened-up.

Audioengr, I'm ONLY questioning reason for bringing NEW components to a show. Show schedules have not changed for years so no excuse IMHO not to prepare properly.

When I move my components, it takes days to settle so I understand Sun has the best sound.

I had TAD E1's in my room 2 years ago at Newport show. They claimed they were broken-in. They weren't. Took 2-3 days before they opened-up.
From my experience, it takes ~350+ hrs before E1 opens up. I would not show unless 500+ hrs.
Audioengr, I am speaking only about the main TAD room. There were lots of rooms with their speakers this CES and THE Show. At least one was the result of their speaker not being delivered on time.
King - I agree. I have stopped partnering with companies that cannot properly prepare for shows. I have been left high and dry sometimes. There is no excuse.

I finally found some really good ones that have outstanding equipment and work hard to do each show, Vapor Audio (vaporsound.com) and Antipodes Audio. No slackers there.
