Hi Dennis,

Would like to know if you'd be interested in making 7x200W multi-channel amp for Atmos/Auro3D pre/pro/receivers that need +11 amp channels to drive all those speakers?

Also, do you have a silver color option available?

Rumor:

D-Sonic is working on a new case option for this amplifier that has a low-profile height and rack-accommodating width.

Looking forward to it. On the fence, but this could help.

I've joined the D-Sonic family. I picked up the 7-2800. Very nice looking amp and can't wait to get it all hooked up!

Was there ever any discussion in this thread addressing whether DSONIC modifies the newer modules and or has a custom input stage?

I'm another one on the fence between Ws4 and d sonic

Peter,


I use ICEpower im the M2-1500-3 only. All other models use different technology, not Hypex.

I don't know what W4S currently uses, but if they're still using ICE modules then I believe they're different.

Dennis uses Pascal and Anaview core amplifiers. The Anaview amps are designated with -A. If I am not mistaken, Dennis modifies the input stages for the Pascals but not for the Anaview amplifiers. In any case, Dennis can confirm that for you one way or the other. I own 3 M3-600M-A (Anaview) amps for my LCR (Danley SM60Fs), a M3-2800-7 (Pascal) and M3-2000-5 (Pascal) for 12 surrounds (Reaction Audio CX-8 Be).

I am looking to replace my Krell Showcase amp with the same 7-2800 you have. Would love to know what you think. Especially compared to NAD M-27

I have zero experience with NAD but I've been pleased with the DSonic. I had a couple of B&K amps in the past and actually just ran my receiver for a bit since my speakers are so efficient. I also had the Sherbourn 7-350 for a short period and I feel this is a much better built amp than that. What complicates things sonically is that I'm driving new speakers as well.

There are a few people on here that have had their amps longer than me and hopefully they'll chime in as well.

I've been thinking about selling my Emotiva XPR-5 and trying a D-Sonic M3-4000-7, but I'm not sure whether it would be an upgrade or not considering the non-ICE modules. Mainly need a 7 channel amp that delivers power in a compact form as rack space is limited.

The d-sonic amps aren't necessarily small, but I guess it's smaller than adding another amp to your rack. From everything I've heard the new amps are better than the ICE modules, but I can't speak from first hand experience as I own one of the ICE module amps. The XPR -5 is a nice amp from what I've heard. I have an Adcom 7707, which is a very nice amp, but I like the D-Sonic amp more and that is pure unprofessional bias.

It looks like, at least to me, that the D-Sonic amps aren't as tall or deep as the XPR-5. The XPR-5 is 9.5" tall and weighs over 100 pounds. Since the amp section in the Denon X7200 is so anemic, I was looking at either getting a 7-channel amp that has a similar footprint of the XPR-5 or possibly adding the D-Sonic 3-channel M3-1200-3 to give me 8 channels of amplification at 400 watts. Since the M3-1200-3 is $2K, I was thinking, might as well spring for 800w x 3 + 400w x 4 and sell the XPR-5, which would pay for half of the M3-4000-7.

I liked the sound of the ICE modules but not sure about the Pascal ones.

You'll gain an inch and a quarter in height, 18.25”W x 15.6”D x 8.25”H, from D-Sonic's website. They're definitely lighter: 50 – 58 lbs.

I have the ICE models in mine, though not in use, but I'm very curious about the newer amps.

The newer Pascal and Anaview models are supposed be significant upgrade over older ICE modues.

Hello All-i Recently replaced my Bryston with a three channel Dsonic amp. I now am a getting some hum which sounds (although im not sure) like a ground loop. No other changes were made to the system. I have tried the standard diagnosis of plugging and unplugging power to other components to see if one of them will stop the hum. No changes were heard with the unplugging of any other component.

Anyone have any ideas (its also not the subwoofer) as to the cause of this- or if its something particular to the dsonic amp? Any suggestions are welcome.....as said before. no other changes made except swapping the amp.

There is a thread on resolving ground loop hums. Are all the components on the same circuit?

Pulled the trigger on the M3-2800-7 and am glad i did. Much more head room than my Krell. This might be because of the power difference. I dont feel like i lost anything in the switch, a definite positive. Asked Dennis what amps are used and he replied i have all Pascal. The amp is much larger than i thought it would be. Only thing that threw me off was the switch for XLR or Low Level on each channel. Never had to do that before. I plan on keeping my D-Sonic for many years to come, dont see how i can improve on it at this point.

Bought M3-1200S-A this week from Dennis after harassing him with incessant questions about the amp, but I though that was necessary since I could not hear the amp before buying it. Dennis was very patient in answering all my questions. I had already replaced my Outlaw-770 with a used D-sonic Magnum-3500. The older D-sonic has older ASP modules.

Someone had asked a question earlier in the thread about newer modules. All I can say is, do not give it a second thought and if you are in the market for an amp, give M3 amps a shot. I have not listened to other M3 models, but M3-1200S-A is a winner. This is without much of a burn in. People say they get better with burn-in, I'm not sure how much, but I can be perfectly happy with its current performance.
They are more dynamic than older ICE modules and top end is more airier than older ASP modules. Dennis described them to me very accurately when he said they sound like listening to live music. I could hear nuances in Ry Cooders guitar for the first time in "A meeting by the River". The amp brings out details from the music. Bass was also spectacular, but I was kind of expecting that:-) I'll post something later if I think they got better with burn in.

I would like to get another M3-600-A for my center channel when the budget allows.
In the meantime, I'm trying to figure out a way to use those 2 unused modules in magnum 3500. If someone can pull those out an put them in a nice case, I can have a good amp for a second bedroom/office system.
