Class D is just Dandy!

@eric_squires

Thinking of buying the d3020 for my daughter's room and pairing with a pair of epos els3.
Sources would be a tt as I see the v2 now has a mm phono input and a PS3 via toslink.

Do you have the v2?

I do not. I have the v1 which has a USB input instead. 

Best,

Well I bought a NAD D3020V2 and have to say pretty darn impressed for the money.

Great features include a built in MM phono stage, an additional analog input,a toslink input and a spdif input. Another nice touch is a subwoofer output. Add all that to its tiny form factor, if you cannot find room for this then there is something wrong!

Sure 30wpc is not going to rattle the roof beams but paired with Epos ELS3 speakers it plays louder than I need it to.
Oh headphone output as well so very hard to criticize for a bedroom unit or third system which is where it now resides.

$300 shipped as a factory NAD refurbished unit with full warranty.

So, with all of this Class D talk, where to the new ATI 52X and 54X rate in the scheme of sound quality?  How do they compare to the D-Sonic and their Pascal modules?

jwincville22,

You’re likely getting no responses to your request for sound quality reports on the 2 newer 52X and 54X ATI class D amps because you’re only reaching members who own one of these specific amps AND happen to still be following this long running thread. You may get more responses by starting a new separate thread.

Sorry, I’ve never auditioned any ATI class D amps but I can verify that the D-Sonic M3-600-M class D mono-blocks I own are excellent amps.
However, I bought mine about 4 years ago when they utilized Anaview/Abletec ALC1000-1300 class D amp modules. Anaview discontinued the ALC100-1300 modules in 2014 and I believe the current D-Sonic M3-600-A monos utilize the newer Anaview AMS-1000-2600 modules. I think D-Sonic only uses Pascal modules in their top of the line M-1500 mono-blocks.
Both Anaview and Pascal are Scandinavian companies and their class D modules differ from most by combining the amp section and the switch mode power supply (SMPS) on the same board. Most other class D module design/manufacturing companies, such as Hypex-Ncore and B&O-Ice, offer the amp sections and SMPS as separate products on separate boards.

I asked D-Sonic’s owner, Dennis Deacon, back in 2014 about the sonic differences he noticed between the Anaview ALC-1000-1300 and AMS-1000-2600 modules and here was his response:

" Tim,

I have been shipping amplifiers with the new AMS1000-2600 modules. The sonic differences with the previous ALC1000-1300 are very subtle with most source material. They do have a more natural resolution of detail and a more natural impact in the upper bass to lower midrange area. This is where most big dynamics are heard such as percussion, cellos, baritone and bass horns."

Here’s the name of that thread that you might find useful and interesting:
