I did get a visit about a year or so ago. I was considering a 7 channel but was holding off as he was working on a 9 channel (I run 5.1.4). As I'm mostly music now (vinyl particularly), I went the tube route for my front L & R (Rogue Magnum II - excellent amp). Currently using an Emotiva UPA7 for the rest, but thinking of a class D for heights, MRX720 for surrounds and center, and selling the UPA7.

Glad to see I’m not the only as my 5 year old amps runs warm to hot. Anyone know why this is ? Given it’s a class d type Maybe that’s why it sounds better than other class d amps I’ve heard

I wish D-Sonic had a legacy section on their website. Hard to get information from the old Magnum series.

He's great responding to emails and I live in New Zealand so probably wont call. However it would be nice to have that available on the website. None of their previous product information is available.

Dennis has been busy. But he generally responds to email by the next business day.

The lower powered amplifier modules are almost ready. My guess is ~ end of Q3/beginning of Q4. Email Dennis ([email protected]) for pre-order info.

This is late but I want to thanks Dennis for providing amps to drive our Selah Audio speakers at the recent LSAF in Dallas. The sound was great and we had plenty of power for bi-amping our Omaggio line arrays.

Have any third party tests been done on any of the D-sonic amps? It’s hard for me to imagine buying one of these blind without seeing the facts regarding performance. The power and price look very good.

I was in the same boat as you. I'm not a tight-wad, but I also don't like to waste money, I do like knowing what I'm buying up front for the most part. Looking, touching, testing - so I was reluctant to pull the trigger on my amp when I had some great choices (Anthem, Parasound, Classe, etc.) locally - but on a recommendation from a fellow forum member, I decided to investigate D-Sonic. Landed a lot of key features for me at a reasonable price that the others couldn't. But would it sound good? .......well, I've never looked back. With modern amps like this, even being a small company as Dennis is, I don't get too hung up on the "numbers". But I can appreciate people wanting to know of course.

I think the power choices available, low profile (if that matters), cooler running, rock solid build, and support than Dennis gives at this price point is a bargain. You can always in-home demo it and return it if you're not happy.

External amplification is something I have just started researching, but I'm starting to be more interested in having the extra power on tap for dynamic peaks. More and more I'm starting to think that the extra power, along with sensitive speakers that can handle the power, are what sets the really great systems apart. There is obviously a reason that some of the most knowledgeable members have 100dB+ sensitive speakers combined with 4-800+ watts on tap. It's still surprising how dynamic and powerful things are in person(without being uncomfortably loud) compared to how they sound played back on speakers at home.

A high quality external amp is also something that doesn't necessarily get outdated or need upgrading or replacing as AVR's or processors do over time.

I initially started looking at the XPA-3 and Monolith 3X(2-300w/ch @ 8r), but at that price point, I figure I might as well get even more dynamic reserves instead of just a modest increase as those two would offer. The power levels offered by the D-sonic amps are incredible and, compared to other brands, seems like the best value that I have seen.

There are much more detailed specs available on D-sonics website(didn't realize this at first) that come straight from the amp module manufacturer. A lot of them are still over my head as far as fully comprehending what is really important, but that just means its time to do more reading and research until it all clicks.

Although I'm not ready to pull the trigger on an amp yet, the M3a-1200-3 is my top contender at this point. I've ruled out Class D Audio, as, although their prices are quite low, they don't offer a 3-channel nor nearly as much power. Again, if I'm going to spend the money, might as well go to the top imo.

I'll be driving a pair of DIYSG HTM-8's and a Fusion 8 MTM center channel with a 10-12' listening distance.

From the little I've read up on the topic, the things that matter a lot are power output, distortion, frequency response, noise floor, SNR, IMD. Channel separation(not sure what this means). I'd be tempted to send one to Notnyt(if he were interested) for testing if I bought one just to see what he comes up with as I feel like he has a really solid grasp on electronics(certainly compared to me).

Anyone know if the 3 channels still come in the narrow chassis, or the regular multi channel chassis that is upgradeable?

Yep. The 3-channel can be had in that taller, "squishy" chassis that I don't too much care for because of the shape, or the "regular" chassis - but it is more expensive because the power jumps from 3 x 400w to 3 x 800w. You can also get 3 x 1500w in that regular chassis. I much prefer the later since it approaches a more standard component width, though the chubby chassis is not as deep (which could be an advantage in certain AV cabinets).

Keep us posted on your "amplifier journey"!

I'll have to ask Dennis if the 3x400 can be done in the wider regular chassis for a similar cost. Not close enough to a purchase yet to bother him about it though as I'm probably six months out from saving enough. I have myself on a pretty strict budget for home theater at the moment. Even the 3x400 is more power than I need and I would consider somewhat of a future proof purchase with room for unforeseen upgrades in speakers etc. The narrow chassis isn't a deal breaker for me, but I'm assuming the wide chassis can be upgraded to more channels in the future.

I'd think the 3 x 400w could be done in the regular chassis? I mean, I've got the 7x400 in that chassis, so why not? But maybe something is going on inside that I don't realize that makes it easier said than done. Heck, even though you're not ready to buy just yet, send Dennis an email! Then at least you'll have that knowledge up front to chew on.

All looking for some information about D-Sonic vs PS Audio M700 Class D. I have been testing the M700 and they have been good but want to know will the Pascal Class D be better than IcePower when it comes to the lows at low volume. The M700 have been good but don't know if I am getting the lower extension and dynamic range I want.. Focal Electra Speakers 1028be towers.

Appreciate the feedback.

Zero likely difference in your scenario. For lower extension you need a subwoofer (or two) or towers with lower extension.

The M-700's are rated +/- 0.5 dB 10Hz to 20 KHz. So unless you are concerned with below 10 Hz from your speakers, it would seem as though they are sending a pretty accurate signal.

However, their website certainly lays on some mighty flowery drivel about the "sonic signature" which, in my book, disqualifies it from being an accurate amp:

"The design closely mirrors the sonic characteristics of a vacuum tube and allows Myers the freedom to voice the amplifier as he sees fit. Long hours of listening and tuning sessions in Music Room One, shared by PS Audio founder Paul McGowan and Darren Myers, resulted in a sonic signature that honors the music and never draws attention to itself.

The listening experience with the M700 starts feet tapping and smiles breaking out. The M700 presents music without a hint of glare. Listeners are constantly surprised at the width and depth of the M700’s soundstage; its preservation of the smallest details in reverb, room acoustics, musical overtones; its commanding presence without intrusion; it’s delicate handling of subtle shadings; its authority as it grabs hold of the loudspeaker and breezes through even the most complex musical passages."

Thanks for pointing out this review. I'm considering the D-Sonic M3a-2800-7 and I haven't been able to find many recent reviews of D-Sonic amps.

There are not a ton of reviews out there, but I think Dennis is O.K. with that. He gets good business by word of mouth. And you have my word, these are awesome amps. And Dennis is fantastic for taking care of his customers. I have the M3a-2800-7, and I love it. Low profile, but do note that is does have some length (depth) to it, so make sure you've got enough front to back clearance, factoring in connectors.

Not the end-all of reviewers by any means, I jumped into separates a few months ago including the M3a-2800-7 (connected to Marantz AV7705). The combo replaced a Pioneer Elite integrated receiver (rated at 135W/ch).

Well, so happy to have moved into separates, and I love the "headroom" of the D-Sonic...definitely hear more dynamic range from the speakers as the amp is not straining (currently 5.1 system, but evident in all modes). Definitely get more volume, especially listening to 5.1 music, but without distortion...the integrated amp definitely projected the "loud because of distortion" sound, while the D-Sonic has more power than my speakers could handle at max volume...in other words, I can listen loud without distortion now.

FWIW, two thumbs up here for the D-Sonic.

Main: Marantz AV7705, D-Sonic M3a-2800-7, Oppo BDP-105D, Sony UBP-X700, DirecTV, LG C8 OLED TV; L/R: Ascend Sierria 2s; C/SL/SR/SW: older Energy series speakers (EC-200/RVSSx2/ES-12)
Headphone Only: Desktop-->Teac UD-301 DAC -->Schiit Mjolinir Amp-->Sennheiser HD800

If you are trying to make a well informed buying decision, the extremely detailed specs available on D-sonics website for its amplifiers will tell you more than a subjective review using flowery audiophile verbiage. Just my opinion, but thought I'd make sure you knew the facts are available. Power, distortion, IMD, SNR, frequency response, etc.
