High end Class D amps?

tvad:" @noble100, what module is used in the D-Sonic amps? Do you know? I went to the site, and did a quick internet search and could not fine the info. Apparently in the top of the line model it’s not an ICE module."   

Hello tvad,

     My D-Sonic M3-600-M monoblocks are over 6 years old now and are their previous model.  Mine use Abletec/Anaview class D modules.  Their latest M3a-600-M monoblocks are the same price but use Pascal Pro2 modules, that have switch mode power supplies incorporated into the module.  I believe these are the same modules that Rowland utilizes in their Continuum S2 integrated amp.
     D-Sonic's owner, Dennis Deacon, told me when the M3a-600-M monos first came out that he thought the Pascal Pro2 modules subtly outperformed the Abletec/Anaview modules in my M3-600-M amps.
     I know D-Sonic's top of the line monoblocks have gone through several upgrades and corresponding model number changes over the past about 6 years since I've been aware of them; from the M2-1500-M to the M3-1500-M to the current M3a-1500-M models. 
    Sorry, I'm not certain about the specific modules they used in each but I do believe they haven't used Ice modules in their top of the line monos for at least 6 years, if ever.  I'm fairly certain, however, that Dennis Deacon would give you the details if you called and asked him: 800-862-7998.

The Lyngdorf TDAI 3400 is the best amp I’ve heard for the money, with Room Correction built in too. Truly superb.

I’m currently running an Aavik U-380 integrated. It replaced a great set of A/B mono blocks because it has all the warmth of the A/Bs coupled with all of the previously mentioned Class D benefits too. Class D has clearly turned the corner in my opinion. 

Fellow Aavik user here. A really articulate and rich sound. The DAC and Phono stage are stunning too. Ditched my £6000 phono stage as the Aavik was clearly better.

I’m in the amps sound similar camp, especially after doing my own blind testing (which was a revelation).  I think the Ncores and Purifis have essentially solved any deficiencies.  But one thing I will certainly concede: an underpowered class D amp is a horror show, and you probably need more rated power (since the D amps are not rated on continuous power like AB).  But these more recent modules have plenty.  I use an NCore module design with my Harbeths and it works beautifully.

One thing I find reprehensible is the way the big names have added all kinds of tweaks to Putzeys’ design (op-amps, power supplies) that are completely unnecessary, or even cause spec deterioration, so they can charge more.  Even his own Mola Mola seems gratuitous.   A clean custom-build, like March Audio, is much cheaper and arguably better-performing than the more expensive name brand versions.  Of course you give up the credit behind the warranty (Alan March is a one-man band), but you could get twice as much amp for the money, and Alan’s been around a while.
