Hi Guys, I've been following all the talk about "settings", and it's been so long, I had to check the DAC. As for the transport, I have always favored 24/356.8, or 8x's, and the DAC at 4x's. Filters are "FIR" and S Dly 2.
But, that was with the Dynaudio Temptations, and now I have the Legacy's in place, much more bottom end and ribbon tweeter, the sound may benefit from a different set-up. So, time for some changes? We shall see. |
FYI...learned yesterday that the driver for MacOSX is not yet up to working with v10.10 (Yosemite) of the O/S. Esoteric informed me that for now, we should utilize the non-async (HS-1) mode for USB input....they will notify as soon as the USB chipset vendor remedies this issue with the driver. Normal non-async playback should work as before with iTunes, JRiver, etc....I think this implies we have to hold off using HRAudioPlayer for now until the USB driver underlying that player is fixed. |
Guido, your welcome, they are good guys ! Tom |
Excellent info Tom... Thank you so much! G. |
Guido: I had a bit of ringing DLY1 but it was minor; major diffs were the more accurate and deeper soundstage (particularly depth here) that DLY2 gave. Also thought overall notes and colors were rounder and fuller without bass being bloated and while keep the very nice transients and "good stuff" in the upper frequencies. The combination of FIR on the P-02 with S_DLY2 on the D-02 seems to be the magic touch at least for now; I'm sure how I'm clocking figures in as well..... |
Scott Seftons official title at the time was marketing specialist, and his boss and truly the force that makes things move is Paul Wasek, national marketing manager. There emails are scott.sefton@us.onkyo.com and paul.wasek@us.onkyo.com, they were both very helpful with all things Esoteric back in August. |
Hy Zephyr, very interesting that your findings on filter selection for D02 are consistent with my preference on K-01... May I ask how S_DLY2 and S_DLY1 differ on D-02?
Saluti, G. |
All: Thank you for the help and advice from the K series and the 02; I've done a LOT of testing of permutations and track by track compare over the last couple of days with the various filter and upconversion & protocol options for PCM on the P02/D02 and this is where I think I'll stay for a while as it gives;
- the biggest, densest and deepest soundstage
- best imaging in all 3 dimensions for the 'crucible recordings' I've used for testing for years
- the deepest, most accurate bass without over-bloom/muddiness
- the most pleasing and roundest notes, best transients and overall musical experience thus far
Caveat: I've stayed away from PCM->DSD on purpose for now. Will test that later after I burn in pure DSD for SACD once the PCM circuits hit 500 hours each. Then we're on to more testing and then even more with the high-throughput USB options; should be done about this time next year at 500 hours per permutation !
Here's the config;
- up-conversion PCM->4Fs (176.4) on P-02, 48-bit ESL3 seems to be the silver bullet!
- digital filter set to On (P-02), resulted in slightly tighter bass, thought FIR on the transport and anything on the DAC would redundant but it really seems to do wonders so filter on P-02 is back on!
- P-02 set to output ESL3 protocol, 24-bit 352.8 is impressive but 48-bit ESL3 176.4 is the best thus far (note above,...skipping test of DSD for now). D-02 set to receive ELS3/176.4 so 48-bit input on dual AES
- up sampling set to 176.4 (D-02), ELS3 *dual XLR inputs", this is 48bit output!!!
- digital filter set to S_DLY2 (D-02), no ringing, all the right elements as highlighted in my opening passage, amazing filter, at least on this system
- clock frequency 22.5792MHz master clock output from D-02, P-02 clocked to D-02, still don't miss the G-03 given clocking improvements in D-02. 22.5792Mhz sounds better than 176.4, the 512x over 44.1 seems to really round things out nicely with the right combination of precision and musicality...
That's all for now, let the burn-in continue :-) !!! |
Hi Tom, This is good to know... does this mean that Scott is Esoteric Sales/Marketing/Operations manager for Esoteric at Integra? |
He was given the responsibilities of Tim Crable, as he retired. He told me that corporate was grooming his official fit in the there new program, but to contact him with anything I needed. I had an issue with my G-01 clock, it would not lock. The music would play, but the clock wouldn't stabilize. So after a lot of back and forth, and a call to the East Coast director of operations for Integra, they sent me a brand new clock, which was the right thing to do. After inserting the clock into the system I couldn't critically listen without it. Scott was a big part of the transaction. |
Hi Tom, what is Scott Sefton's function/position at Integra? |
On the AERIS, I spent a year tearing my brain apart over making the change from the purest analog chain (with digital source) I could put together at the time and the moving to a config that would insert an A-to-D-to-A processor into the circuit as well as demanding overall 3 more power cords and another set of interconnects. I did a lot of listening and commenting for AERIS prior to getting them on quite a few occasions, all at Legacy with Bill while he was going through the various post-intro changes that resulted in the final and current shipping config (ultimately many changes in the bass/sub-bass section were introduced, the passive radiator, upgrade in amount of amplification in each tower, etc...). I finally got past the whole "bringing new complexity to the rig" issue and am so glad that I did. I loved the FocusSE's, they punch far above their weight-class as the boxing term goes but what the AERIS bring in terms of increased presence and many other things with that open-air top-end is something special to say the least. No looking back now, the bar has definitely been raised. All this said knowing that I have not even tweaked the speaker with the XILICA proc; it's still using the "AERIS_Normal" curves that Bill ships with the speaker. I have a mic-kit, mic-preamp, etc...all ready to go. Next step now that the 02s are in, is the mic the system and work with Bill/team to get custom curves for my room and setup. FUN!!!
Footnote: The Kimber Y-cables that come with the AERIS are of extremely good quality; the Y cable is necessary to split the 2-channels into 2x2 so that there is a duplicate of both the L and R input analog signal. I did see a SUBSTANTIAL up-tick in performance, musicality, etc...by going with a custom-built Y-cable (thanks to David Elrod) to match my existing interconnects; it's something I would suggest to anyone who owns AERIS to match your interconnects.
As as aside, Bill told me he uses 4 instead of 2 inputs on the XILICA to allow him the greatest degrees of freedom for designing the curves on the AERIS (time, frequency-related, changes, etc...can be made separately on L and R input copies independent of each other, the XILICA then puts the next effect together for L and R and sends it out to the speakers. I heard it both ways (2 inputs versus 4 to the proc) and what is possible with duplicated inputs and separate tweaking on each is impressive.... |
Thanks...I have Cedric M.'s contact info and can share that in return; he is now the one and only Tech Support guy for Onkyo/Integra that tends to Esoteric. He's a great guy but I sense he is overloaded. Ping me on in-mail and I'll send you his email address and gladly take Scott's in return. I'd love to hit the lottery and go with the P1/D1 however I remember Gurvey telling me prior to the P02/D02 being released that something 'special' was coming and like the 03 generation at the time, that unless you can justify the extra expense for the 01s fully decked out to get that last .001%, that the step down would NOT disappoint in the least, particularly for SACD (he was right then, and I think he's right even after his departure on this point). He was actually the one who recommended checking out the G-03X to fill the gap after I sold off my G-0s clock; he told me that to his ears, the upgraded OCXO clock brought the right level of precision while still preserving musicality, etc....I love it when some of these manufacturers get candid and 'open the kimono' a bit to their own thoughts on the stretch-expense factor. Reminds me of a key conversion with Tom Maker from Edge; I was at a point where I could have gone with the NL Signature Monos (more pricey than what i have) but Tom told me he felt, his best and most current work was in the NL 12.1s and unless I was fixated on monos, that I should save some money and go with the NL 12.1s. When something like that happens, that persons gains a huge amount of respect in my book. Anyone willing to leave a good amount of $$$ on the table (particularly when the purchase is direct) by sharing an opinion like this is usually, if not 100% of the time, giving the best advice you can get.... |
Zephyr, Scott Sefton is the contact guy for Esoteric info. I have his e-mail and will pm it to you if you want, let me know!
Tom |
Hey Zephyr, I hear you, my wife was glad to see me sell some of the old stuff off. Need to be quick with resale, but the D-02/ P-02 are not coming down in value, still pretty strong, and like I say, they are still the best alternative to the D-1/P-1 Grandioso.
As for the Legacy Aeris, I am thinking of auditioning them, I have heard a lot of good things about them.... Great mid-bass and midrange, and of course the signature deep bass. Glad to hear you like your set up, since it would be similar to me if I go that way. |
Thank you all! I don't think setting PCM->4fs (or other setting) on the P-02 and also indicating this on the D-02 results in double-up on the up-conversion, more like telling the D-02 what's coming in with the exception setting PCM->DSD on the D-02. I'll have to chase this down with Esoteric to be certain. I would think that I should not set a filter on the P-02 and then have it on the D-02 any longer but I'll track that down with them as well. I'll report back what I find out and what I hear.
Colekat: I moved to the Legacy AERIS a while ago and am extremely happy with what the new models bring. I still appreciate all the Legacy SE brought to the table; they were fantastic speakers. The AERIS however are amazing and I'm staying with them for quite some time. The new "V" sounds and looks amazing but I don't know if I can get it into the house, and if so, don't think I can get them past the boss for approval :-) they are massive and beautiful to be certain. |
Hey Zephyr, are you still using Legacy Focus SE's ? I have my Legacy's set-up with the main system and they sound great. No better bass for the money, smooth, coherent, powerful and forceful! I can feel the thump right in the center of my chest. The D-02/P-02 brings out the best in everything I set them up with. Just wondering, and if you are, I'm sure you are presently surprised. |
It's hard to believe these components are entering there fourth year. With Esoteric releasing the K-01X the D-02/P-02 combo may become somewhat scarce, with everyone opting for the K-01x. Esoteric has told me that there is no upgrade planned for the D-02 for DSD over USB, however, it is not ruled out. I think that will make the D-02 a bit of a novelty, although still a better sounding set up than all but perhaps the new D-1/P-1 Grandioso. The D-02 owners hopefully can stick together and help each other get the most out of this awesome combo... settings, preferences, cables, footers, etc. We are probably disc spinners, mostly SACDs, although the D-02 is great with computer and servers too, but without DSD, everyone is over looking these babies. Anyway hope to hear a lot of sharing info and swapping experiences, let's keep this thread rockin'. |
Zephyr if you do check with esoteric let us know what they say. I have also asked that question myself many times. You can do the up conversion either at P02 or D02. Or you can do it at both. I do it only at the P02 level and leave the D02 as ORG. Do not think doing it twice makes sense. Although it could be better to do it at the DAC. As for filter I use none, but if I decided to try some I would be also interested to know if better at transport of DAC.
Also check out the XLR gain at 0 or + 6db. It does change the sound. |
Hi Zephyr, I have no experience on the combo units at all... My findings are based on K01 only.... By logic only I imagine that if you set filters on D-02, no filters should be set on P-02... But it might be best for you to consult Integra/Esoteric tech support on this.
On K-01 I much prefered the resolution, spatiality and the overall musicality of 4X upsampling over 2X... And I preferred 2X over no upsampling at all. |
Thank you Guido...I will give it a try and burn it in for at least 2 weeks before judging. The big question is do you disable the digital filter on the P-02 as they could overlap in function and what up-conversion on the P-02 do you have set? I have heard thus far that 48-bit ESL3 4fs (to 176.4...) seems to be the best though I have not spent a ton of time with PCM-DSD as I found was the best on my P-03U/D-03. What is the complete set of options that you utilize across both transport and DAC? Thanks!
Eelii008: Thanks....don't know if it will help it move any faster though I am hoping! I'm really looking forward to the next few years with this rig and beyond! |
Hi Zephyr, my experience on K-01 first edition was that each filter variant required its own break in time of about 500 hours. For my own preferences, S_dly2 met the right balance of resolution and musicality.... S_dly1 was more tube-like, while DSD upsampling resulted in a highly resolving and snappy, but also "nervous", rendering that resulted in an edge-of-seat experience that I was not too fond of. FIR filters seemed to yield a bit of a two-dimensional stage with a touch of synthetic in their sound signature. |
Zephyr saw your add. Very well elaborated. Mine is a piece of c*** in comparation. Maybe I should edit.... ;-) |
Good to see you all again. Zephyr you sure are positioned to get great music time ahead. And when you get use to it, a few months in the future, do consider the clock.
I myself have the 02s listed for selling. Let's see if I can also get a good home for them. There are a couple listed lately. I would upgrade to the 01s, although the 02s are so good, that I think if I don't sell them I will hold on to them for a while still. |
Thank you...I'm sure I am and a hell of a good dose of burn-in on multiple paths and testing/re-testing/etc....! Let's keep this thread alive for sure...enjoy the game and happy llstening!!! |
Hey Zephyr, Congrats on the D-02/P-02 combo, you are in for treat, but you know that already. I was thinking of you this week, I sold my Dynaudio Temptations and set my Legacy Focus 20/20's with the main system until I make a decision on what my new speakers will be. Must say the Legacy's sound terrific with the Esoterics!
Anyway, hope this thread grows some legs again, look forward to hearing about your impressions of the D-02/P-02's.
And great to see Eelii again, talk to you guys later... Go Patriots, time for some football. |
Guido: Great to hear from you as always! I hope life and audio are treating you well! I have tried S_DLY1 and briefly S_DLY2; perhaps it's the fact I have alot of burn in to do on these permutations of settings the P-02 is nearly brand new and the D-02 has had about 1 good year of use.
What overall combination of settings beyond filter S_DLY2 did you find best? For example, are you using PCM->4fs or 8fs (or DSD)? Would you suggest I use no filter on the P-02 and S_DLY2 on the DAC?
Did you find every filter had to be burnt in separately or is there one common circuit path that does not necessitate the individual filters each need to receive 350+ hours?
Thanks or the help....I can tell this will be an even longer road to finding the optimum setting than the 03 generation; and then there's the USB input options,.....ah,...much more burn-in there too :-)
If anyone's interested in a P03U, D03 and G-03X package, I posted mine this morning and will love to find them a good home... |
Hi Zephyr, may I suggest to give S_dly2 a spin. On K-01 at least, I found it to be more extended than S_dly1, with greater staging/imaging, and equally musical.
G. |
Congrats. I play it with up sampling at ESL3 at transport, so 48/176.4. At DAC I leave up convert to ORG. In my case I do not use digital filters but have to say have not really tired extensively any of them.
Clock frequency as you, but with the G01. I think you are doing well by selling the G03. In my opinion you will get better results using the D02 alone. At some point in the future do try the G01.
Congrats |
I've done additional testing both with and without the G-03x and the master clock in the D-02 yields at least equal results to having the extra OCXO standalone clock (G-03X) in the system. I currently have pulled the G-03X out of the circuit and will now post it with the P-03U and D-03 when I offer them.
I've got the D-02 set to output a master word clock out at 512x44.1 (22.5792 MHz) to allow the full range of upconversion rates and DSD playback with the P-02 slaved to the D-02's master clock. Great results,...here is the current config;
- up-conversion PCM->4Fs (176.4) on P-02
- digital filter set to On (P-02)
- P-02 set to output ESL3 protocol
- up sampling set to 176.4 (D-02), ELS3 *dual XLR inputs", this is 48bit output!!!
- digital filter set to FIR1 (D-02)
- clock frequency 22.5792MHz master clock output from D-02, P-02 clocked to D-02 |
I was able to find another D-02 in 9/10 condition from an outstanding seller on Audiogon (see my most recent feedback, this guy is great to deal with) and solve my immediate issue; the D-02 has arrived and is up and running with the P-02 as a matching set thus replacing my tried and true 7 1/2 year old P-03U and D-03 which will get posted shortly.
All I can say is "WOW!" in terms of the improvements that the new 02 combo brings to the table; they extract so much more from anything I've thrown at them and provide a massive sound stage with incredible depth and great imaging while still providing a very organic and musical presentation. In addition, the frequency range and particularly deep bass resolution and extension of the new 02 combo is truly "off the charts!"
I've experimented with various settings in the first 24 hours and thus far I am tending towards burning in the following combination first;
- upconversion PCM->4Fs (176.4) on P-02
- digital filter set to On (P-02)
- P-02 set to output ESL3 protocol
- upsampling set to 176.4 (D-02), ELS3 *dual XLR inputs"
- digital filter set to FIR1 (D-02)
- clock frequency 176.4 with G-03x driving (will try D-02, no G-03x at some point)
I've read several reviewer/other posts and have tried S_DLY1 (apodizing) filter1 as well as NoFilter on the D02 and NoFilter on the P02. Thus far, the above seems to be the best overall settings for my ears and how the units sound now but we'll see how things burn it and how it turns out overall. I will also try up-converting to both PCM via Dual XLR at 352.8 and PCM->DSD up-conversion at some point though initial tests of each seemed to indicate the above list is where I am going to start.
There are so many options with how these can be configured (have not even gone near the USB input yet!) that I look forward to a long and happy set of experiments and alot of listening with these units.
As for that seller of the first D02, a legal demand letter has been issued late last week, and the hunt will continue with the appropriate outside agencies if the DL is not responded to per its terms. If anyone's been through anything like this and can provide feedback/additional ideas please let me know through 1:1 private in-mail. Thank you! |
Happy New Year to all of you...hope you are all still enjoying your Esoteric gear! I would love to be able to move up to the Grandioso P1/D1 level but that is just not in the cards as they say....
I'm in the middle of what will be a hard-fought upgrade transaction with a very difficult seller (have 40+ pages of email and other comms, glad to provide details on this challenge and the seller so people can avoid him,....communicate with me on in-mail) and after a month, finally have a P-02 installed in the system in place of my 7 1/2 tried and true P-03U Transport. The D-02 is still outstanding and will likely become a 'longer story' with a potentially legally troublesome ending (for the Valley Stream & Lynbrook NY-based seller in question) so the P-02 is feeding my existing D-03 Dual Mono DAC with incredible results.
The holy grail of this hobby so to speak, is to be able to achieve very detailed and accurate playback with all possible inner detail retrieved from the recorded medium while also having organic, musical and non-fatiguing playback. As much as I love the P-03U/D-03 combo all these years, it's hard to put into words what additionally the P-02 brings to the table. The difference and upgrade in all these key areas is not subtle and is incredibly impressive! I'm extremely happy with the P-02 after only 2-3 days and cannot wait for the D-02 to arrive! |
The new Esoteric D1 is truly wonderful sounding on my system. It has taken me almost 1 month to run it in. If you have a chance you must listen to it. My CDs have never sounded so beautiful. It is a open and lush. Of course, high-res material sound wonderful as well. It must be heard with a very good USB cable. By the way, Esoteric has a free music player on their website for both Windows and Mac which can be used on their DACs. It can play back native DSD and can also load the music directly into RAM. I had decided not to go with the G1 and use computer playback entirely. |
Hey Pharma, How's everything, well I hope! Just wondering if you have any news on the sounds of the new Grandioso's. I'm not sure they can even be purchased in the States, but if so, I hoping you got your hands on them and have a few words on there performance. Anyhow, hope this gets this thread fired up again. |
I am waiting to hear the new Esoteric D1 Grandioso converter that is replacing d01vuk. I will compare it to d02, d03 and I will try to hear dCS Puccini one more time.
D02 still sounds a bit forward and dry for my taste. According to some European reviews K series players roll off treble a bit earlier than previous players with SACD. I still like SACDs better on D03(more fluent and musical if not as detailed) than D02.
D01vuk and even D03 sounds more laidback. There is definitely old and new sound of Esoteric.
I am hoping that the new D1 Grandioso will offer best of both worlds. |
Hey everyone, Where have you all been. I just set up my new Ypsilon Aleius Amps. They are Hybrid tube input stage, solid state output stage, zero negitive feedback. The D-02/P-02 is already more relaxed and these amps have only hours on them.
Do any of you have any experience with the Esoterics with tubes in the chain. Hope to get this thread fired up again. Hope all is well
Tom |
Hey Opera Lover, Spent better part of yesterday doing a Ypsilon DAC 100 Esoteric D-02 comparison. I've had my D-02 a year now, and would say it is as broken in, settled in, etc. anyway it is "in". The D-02 is by far the best Esoteric I've have heard, and I had the X-01/D2 and the K-01 after that, I still have the X-01/D2 for that matter.
The Esoteric sound as a whole is extremely detailed with incredible resolution, sounds are easy to deliniate and are very well sorted. That hasn't changed from the X-01 to the K-01 to the D-02/P-02, the progression has just gotten easier to listen too. No doubt the current Esoteric stuff is the best so far.
But, if I had it all over to do again, I would have paid better attention to the Hybrid stuff that is out there. After the Ypsilon DAC100 A/B with the D-02, I would not hesitate to move to the Ypsilon. And I love the Esoteric D-02/P-02, but overall, there is a general lack of musicality to the overall sound that was easily noticed in the Ypsilon. Now the Ypsilon has a tube in the output stage and does not upsample at all. In fact it only plays Redbook, and does so at a State of the Art playback. The listening was a pleasure . Now not to throw the D-02 out the window, I am still very pleased with the D-02, it does most things at a very high level, it just lacks a relaxedness to the overall presentation.
So I can see why you would be attracted to the D-01 Vuk, as it surely the most relaxed sound Esoteric has to date. |
Before I decided to give up D-02 (sold already), it continued to run day and night until around 800 hr.
Until the point I thought why I needed to spend several thousands hours just to break in D-02, with unknown result?
On the other hand, second-hand D-01 VUK is readily available with well broken-in.
So D-02 was sold, D-01 was sold, and now D-01 VUK is in home; very relax, with good details at the same time. |
Hi Operalover, at 500 hours D-02 was unlikely to be broken in.... In addition to the basic 500 hours breakin, D-02 likely requires another 500 hours on each targeted filter+upsampling value. Before the machine has settled completely, D-02 is likely to exhibit some residual aggression. On the other hand, an exhuberant stage/imaging may exists by design.
A D-01 unit would have had time to settle down for quite a spell... D-02 at 500 hours is a mere youngling DAC, with all the emotional problems of a tempestuous adolescence.
On the other hand, I freely admit that I am extrapolating from my experience with single box X-01 and K-01, which is a somewhat risky logical proposition... Pharma should comment, having had significant direct experience with most Esoteric front ends.
G. |
comparison done after 500 hours break-in D-02.
tried several upsampling/filtering.
in fact, any upsmapling/filtering setting did not change the fundamental character. (upsampling/filtering only adjusted to the taste preference, not the fundamental character)For example, the exaggerate soundstage, and pushy character.
My friends are amateur concert musicians and conductors. My better-half pointed out the locations of instruments were too far apart compared with those in real concerts.
And more importantly, we were feeling tired after an hour or so of listening. (For example, during the day, we turned on the tuner all the time. We could do so using D-01. But for D-02, we turned it off after an hour or so.) |
Hi Operalover, how many hours of break-in did D-02 have... and what upsampling / filtering settings had been applied on the two units? G. |
while it depends on individual taste, but once people compare D-02 with D-01, you will find D-01 is more relax, comfortable, not pushy, than D-02. (D-01 VUK is even better.)
Might be the technical spec of D-02 is better, but unfortunately audio is not only "made" by engineering, otherwise people do not need to "trust your ears".
Nowadays second hand price of P-01/D-01 is the same as new P-02/D-02, we have one more option.
I have A/B compared D-01 and D-02. Similar comments given by my better-half, and other friends who like music/concerts (but do not know audio) in various occasions.
|
It hasnt been broken in yet with just an hour, and it sounded less noisy, eliminated the least bit of digital haze from DACs made vocals better, made the music flowing effortlessly as a whole. What can I say, it is a steal for this price. The only area that Esoteric 7300 is slightly better is the bass depth, but like I said it is not broken in yet. I can easily say that this is the best $1k pc cable I have heard challenging more expensive cables. |
I agree it made the sound of both D02 and D03 dacs more refined, smooth and lowered the noise plus it is just under $1K. I recommend at least hearing it. They have also Alpha HC for amplifiers and conditioners, Alpha Analog for pre and turntables. If I am not mistaken this Alpha Digital may also work with class D amps. I am not sure if it would work with SMPS tough, probably HC version is the right choice for the amps. |
And the remarkable thing is that the Shunyata Alpha Digital PC is conservatevely priced at $999. |
As for the power cords, or pcs I didnt hear 9500 yet. But the new Shunyata Zitron Digital alpha sounded much better than 7300 in terms of soundstage, openness, noise, etc. I am considering selling my 7300 now. |
6300s are great when used as aes/ebu. There are better interconnects than 6300. They are not the most refined, and they can be interpreted as bright sometimes since they are really extended as an interconnect. I prefer Tara 0.8, or the new more expensive Valhalla 2. A friend of mine likes Gutwire top model which costs around 3.5k over 6300s. I didnt hear it myself. |
Hi Guys, Its been awhile! Just checking in on your thoughts.... I have a chance to buy a pair of Acrolink 6300s, not the new series II, they are the originals. I wonder if I should pass on them, and go for the newest ones!
Let me know what you think!
Eelii, how are the PCs? |
Hi Pharma... I'll drink to that!
Guido |
Hi Guido,
Thank you for excellent info. Looks like there will be more high end brands adopting SMPS to be used with conventional amp. stages.
The SMPS upgraded 700 delivers 600w in 8ohms, and 1200w in 4 ohms continuously versus the regular 700 that delivers 430/860w. Also the THD and IM is lower on the upgraded one.
Thanks again. |
