Ohm Walsh Micro Talls: who's actually heard 'em?

No downside, only positive attributes going all omni from top to bottom. Loren Charles of Mark and Daniel says 100 hrs for full breakin.

Bondmanp, I look up the output impedance for your McIntosh C220, it's 250 ohm, so yes, no problem going into a 10Kohm input impedance amp.

Wow! Thank guys. I talked to John and he told me there was not going to be a specific OHM 3000 sale this summer. But he pause for a second and was kind enough to offer a 20% discount on a new pair of OHM 3000. Of course I jumped on the deal. Thanks everyone.

Forgot to mention, John did first offer a discount on a 3000 driver with the older cabinet but I did not want it. That is when he paused and offered a discount on the newer OHM 3000.

I only have one question. I'm ready to purchase the new OHM 3000. Has OHM ever offered these $4,000 speakers at a discount on the day after Thanksgiving? If not, I will go ahead and start the process of purchasing these speakers now.

Thanks Finsup, I'll wait another month before pulling the trigger on the OHM 3000.

I first encounter the OHM Walsh 4 as a penniless audiophile back in 1985 at a local dealer. That one experience has stay with me all these years. I want to thank John for keeping the faith in these unique speakers and I want to express my warmhearted recognition to the inventor Lincoln Walsh. At 56 years of age, these will probably be my last speakers.

My vote for the biggest bang for the buck in power conditioner is from Alan Maher designs Quantum mini. These sell for $40 each and are placed on your circuit breaker(normally 4 are needed and each are connected to the ground). This conditions the whole house. You will hear an overall relaxing sound quality with purer extended highs and a larger soundstage.

Will do. Wtf

I own the OHM 3000, the only minor complaint I have is the soft dome tweeter is not as extended as a good ribbon tweeter. So I have on order, a add-on supertweeter which will sit on top of the speakers. The new Mark & Daniel Omni Harmonizer AMT supertweeter should arrive within the next two weeks. Can't wait!

Just a quick update. Loren Charles of Mark & Daniel Audio sent me an e-mail informing me that there was some sort of mistake at the factory. My Omni Harmonizer that I ordered weeks ago was never shipped but that they are now on there way. So I have to wait a couple weeks longer to see how well they blend in with my OHM 3000. Yeah, I'm a little upset.

Sounds like you did nothing wrong. Dome tweeters are mechanically fragile instruments.

Finally the Omni Harmonizer super tweeter arrived yesterday. First order of business was to make sure they were in good working order. Hooking them up to the amp output and slowly turning up the volume, they began to sing but I heard nothing special or magical. Next, I added the Ohm 3000 with the O.H. super tweeter running in parallel. First impression was different than what I had expected. Having lived with the ribbon on my Dali Helicon 300 for many years, those Dali ribbons infuse dazzle and sparkle. The O.H. on the other hand are every bit as extended at the top end but are more polite and reserved than your traditional ribbon tweeters. I assume this has to do with the O.H. AMT tweeter's lower distortion figues. In any case, subjectively I chose to set the O.H. attenuation at 0 db. The O.H. are a definite improvement over the Ohm 3000 own built in dome super tweeters, which in comparison, I would describe as slow and dull.

I saved the best for last, because the biggest improvement was down in the midrange as others who have experimented with super tweeters have mentioned. The Ohm 3000 on their own do have a vagueness or slight diffuse center image. The O.H. adds midrange bloom and body which stabilizes vocals and helps to create that believable phantom center image. It's startling at times when the vocalist seemingly materializes in your listening room. The improved midrange also make it impossible to hear where the O.H. AMT's 7 KHz crossover kicks in. Both Ohm and AMT drivers are fast and worked together as one.

All listening was done using only CDs as a source. I'll try to get my daughter to help me put up a You Tube of the Ohm 3000 and Omni Harmonizer playing together soon.

Bondmanp, the Ohm walsh dome tweeters were never disconnected. And I had no issue walking around the room and still getting that huge stable soundstage Ohm walsh driver are famous for with the O.H. connected. The issue of the center image being slightly diffuse may be room dependent but I'm referring to the O.H. ability to give that image more weight and body.

The Omni Harmonizers were placed on the Ohm 3000 grills with no problems. The grills still leave some space between themselves and the top of the metal can that encloses the Ohm drivers. My understanding is that Ohm own dome supertweeter sit directly above the Walsh driver inside that can.

When I get home tonight, I can try moving the OHM/O.H. in and out away from the back wall to see if it's an issue with the supertweeter.

I want to take back my description of the O.H. as reserved on first listen, with about 15 hrs. breakin, they seem to have open up with more extension.

It's my understanding that the crossover on OHM own dome supertweeters kick in at 8 KHz but the walsh drivers themselves are allow to run full range, in which case they begin to roll off naturally above 8 KHz. The Omni Harmonizers which kicks in at 7 KHz seem to me like a natural close fit with the OHM walsh roll off.

Once I started moving my OHM/O.H. in and out between 1 to 3 feet from the back wall, the same old problem of room placement creeps up. At one foot from the back wall and the OHM/O.H. clearly want more room to breath. Three feet give more soundstage depth but at the expense of balance, the low end wanting some back wall reinforcement. What I'm trying to say is that speaker placement has more to do with the main speakers rather than the supertweeters. In my case, for my room, everything gels and falls into place at 20 inches from the back wall to the back of the OHM.

Dsremer, I'm eyeing the D-Sonic 600 w/ch stereo Class D amp for purchase next year. In your opinion, have these new Class D modules surpassed Class A/B and are approaching pure Class A amp, sound wise.

Which OEM provides the Class D modules for the AVM MA 3.2 MONOBLOCKS?

Thanks Dsremer, for your first hand account and opinion.

If you click several times on the open case D-Sonic M2 600 mono thumbnail, the print on the circuit clearly says Abletec Engineering. http://www.polkaudio.com/forums/showthread.php?142204-d-Sonic-M2-600M-monoblocks-amp-Pics.

Coot, is that Placette VCU a Placette Audio passive linestage preamp? If so, you might have an impedance mismatch with the D-Sonic M2 which I believe have an input impedance of only 10Kohm. Actually there some confusion, is the D-Sonic M2 input impedance 10Kohm or 60Kohm? At 10Kohm it will give trouble (roll off highs) to resistor type passive preamp and some tube preamps. If the input impedance 60Kohm, there should be no problem.

At D-Sonic website under the Product tab, the input impedance for the 600W and 1500W output M2 series are listed as 60Kohm. But I e-mailed Mr. Deacon last month asking him what is the input impedance of the M2-1200S and M2-3000S stereo amp. He replied 10Kohm. So I'm not sure, but 10Kohm should be fine for all solid state active preamps and most tube preamps.

You are right but Wyred 4 Sound and other manufacturers include a buffer stage ahead of the Class D amp for the simple reasoning of increasing the input impedance, making it an easier match for tube preamps. I personally would prefer not to have the extra circuitry dressing and go all natural.

Mapman, your ARC SP16 tube preamp has a output impedance of 260 ohms. Using the simple rule of thumb that the input impedance of your amp should have at least 10 times or more, the output impedance of your preamp, 260 ohms * 10 = 2.6Kohm. At 10Kohm for the D-Sonic M2, your ARC tube preamp would have no problems whatsoever.

Your B&k EX442 amp input impedance is 24Kohm and the Placette passive preamp is rather high at 2Kohm output impedance but both should work fine together. At 10kohm input impedance for D-Sonic M2 the high end will begin to roll off. Yes talk to Dennis when you are ready to make the purchase.

Coot, your Placette passive preamp is very highly regarded. You just need to be sure the amp you are getting has an input impedance higher than 20Kohm. Talk to Dennis, maybe his amps really are 60Kohm input impedance which would be perfect with your Placette passive preamp.

Why would Dennis Deacon risk hurting business sales by not releasing more info on his amps? It could be he is overly sensitive about disclosing proprietary information ever since getting Der Wienerschnitzeled by having his business model of selling inexpensive Ice amp on-line stolen by Wyred4Sound.

Early on Dennis DID offer, as an option, a buffer stage to increase the input impedance of his amps but later discontinue it as he found it make no difference sonically even when using tube preamps.

But I'm with you and others who wish D-Sonic would be more open about their amps.

Good news. Looks like D-Sonic has upgraded their amp lines to new M3 models.

At 100 wpc, the $1,500 Wyred4Sound mini integrated would be great with the Ohm Walsh Micro Talls.

I don't know. D-Sonic gives very little info. But I do trust and believe the company if they think M3 series is an improvement over M2.

Coot, I'm interested in anything you bring up on the D-Sonic M3-1500, no matter how trivial.

Coot, did the amp come with any documentation like an owner manual? Do you know the input impedance and the voltage input sensitivity for full output? At your normal listening level is the volume control on your preamp set a little higher, lower or about the same? Good write up, it's what I expected, a more control and tunefulness bottom end.

Coot, the PS Audio Power Plant Premier's maxium output is 1500W, make sure you are pluging the D-Sonic amps directly into a wall outlet. By the way, for break-in purposes the D-Sonic amps only need to be plugged in and turned on 24/7, no real need to play music for break-in.

Coot, thanks for your honest opinion. To hear shrillness coming from your Ohm speakers really did concern me because Ohms have a very mild manner tweeter. I'm shock but appreciate the heads up.

That was a very interesting post, Guido. I was also thinking D-Sonic maybe needed more break-in time by just leaving it on 24/7. You have restored my faith in class D amps. Thanks.

Many people are using the Mac mini(headless) as a music server and controlling itune with an apple remote app or using an apple remote desktop app, like Splashtop on there ipad, neat.
