The Truth about Modern Class D


All my amps right now are Class D. ICEpower in the living room, and NAD D 3020 in the bedroom.

I’ve had several audiophiles come to my home and not one has ever said "Oh, that sounds like Class D."

Having said this, if I could afford them AND had the room, I’d be tempted to switch for a pair of Ayre monoblocks or Conrad Johnson Premiere 12s and very little else.

I’m not religious about Class D. They sound great for me, low power, easy to hide, but if a lot of cash and the need to upgrade ever hits me, I could be persuaded.

The point: Good modern Class D amps just sound like really good amplifiers, with the usual speaker/source matching issues.

You don’t have to go that route, but it’s time we shrugged off the myths and descriptions of Class D that come right out of the 1980’s.

I'm new to digital music, but not analog.  I have a vintage McIntosh system that's been my main system for almost 20 years.

I started building a listening room digital system about 4 months ago.  I'm mostly-retired and didn't want to spend too much on it.  I got a good deal on a new NAD M12/M22 v2 combo, a used pair of Tannoy 8 dcti speakers; and a demo Innous Zenith MK2.  

At first, I was not very happy with my new purchases.  As the equipment has aged and I've bought better speaker wire, interconnects, and power cords, I've experienced a dramatic improvement in SQ - but at times, the highs are still too bright.  I plan to treat my room within the next 30 days, hoping that will help enough.  If not, I'll have some decisions to make.

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.

I use a NAD M12/M22 v2 combination and, overall, I'm very happy with the SQ.  I'm a bit new to digital equipment, and since this is my first digital system, I have nothing else to compare it to - other than auditioning components at a dealer.
