The Truth about Modern Class D

I have owned PS Audio GCC 250w amp since new (still in my TV system), several W4S amps; mono & multi-channel, Emerald Physics 100.2SE monos (much better with special fuses, but still bright). I was about to pull the trigger on a Nord Two (newest Ice tech) when I got a great deal on a Audio Alchemy Stereo amp, and a month later I replaced my Hattor XLR (impedance mismatch) with a AA Dac/Pre. The combination is revelatory. Don't believe me? Search The Absolute Sound March 2016 review. That COMBINATION  produces a natural sound that defies its price point : The combination MSRP is a mere $4000, including a kickass dac

The gamut M250i monos are greath! My friend have those. These are forever.
off course Gryphon is very good! (Diablo)

@georgehif - You should start your own magazine, because even though you don't like Class D you are in every single discussion about it. Call it: 

"Why I can't move past 30 year old arguments." 

Best,

Old school, get professional help from GIK

and don't neglect the flooring, between and behind the speakers. Try using pillows and blankets to test with for free. :)

Erik, thanks much for the advice.  I have throw rugs, over a tile floor, in front of the speakers.  I'm going to try pillow and blankets today!  I saw another suggestion on agon about hanging towels behind the speaker as a test.  I've got plenty of towels and nothing to loose.

The dealer who sold me the Zenith came to my house with an assortment of demo diffusers, absorbers, and bass traps.  I could have purchased them at a good price, but the colors did not fit my taste or room, and some panels looked worn.  But, I will say, the SQ improved with them.  

I'm educating myself on DIY acoustic treatment and have been corresponding with RealTraps.  This past week, I began researching GIK products.  I plan to call GIK after the holidays, send pictures of my setup, and go from there. 

Regarding Class D amps, the NAD M22 v2 uses Hypex nCore technology; and overall I'm quite happy with M12/M22 combo//Zenith MK2.  The sound and SQ is different than that produced by my 90's era McIntosh C31v pre and MC2600 PA; and my 80's era SoundCraftsman SP4001 EQ/pre and Pioneer SPEC-4 PA.  Since the source material, technologies, and speakers are different with each setup, I think that should be expected.  I use each system different.  My vintage analog gear is in a rather large basement bar/sitting/pool room area; the digital gear in my basement listening room. 

If I can warm the listening room sound a bit and reduce the echo chamber effect with the right room treatment (and may different cables, cords, and interconnects), I'll be a happier camper.

About a 18 months ago I got my first class-d amp from Nuprime. They use a proprietary module. 

The price/performance ratio is outstanding with my IDA-16. Completly happy with every aspect of its performance.

Cheers,

Scott
