What going fully Class D has taught me.


Over the past year I’ve been working on a project to transform my main L and R 2-way speakers to active 3 way by adding a woofer tower with a 3-channel plate amp underneath.  This project is finally completed.  My Luxman integrated now sits dark and disconnected.  

The plate amps are made by Hypex, though I have previously used ICEpower based amps as well.  

What I can confidently say is that the old Class D memes have no reason to exist anymore.  I can also say I miss my Luxman sound for music.  

I’ve done this swap before.  I went from Parasound to ICEpower to Luxman, and while I really liked the Luxman sound I was still compelled to attempt a new speaker / amp project.  Many of my objectives have been met.  Very low distortion, high dynamic range, excellent off-axis response and seamless integration.  It sounds very transparent, and realistic for movies.  The low distortion makes high volume listening deceptive.  You don't realize how loud it is because there's absolutely no distortion.  Some of t

What am I missing?  The liquid smooth midrange, buttery treble of the Luxman, which was the main reason I went from Class-D to it in the first place.  What I don’t have is all the normal tropes that used to float around here about how bad Class D sounds.  It doesn’t, it actually sounds really good.  What I need now is a juicy smooth two preamp with HT bypass.

So it sounds like what you've accomplished is great for movies but only so-so for actual music? That would be a non-starter for me since I don't even have a TV of any kind in my listening room.

Class d is comming of age.marantz, audio research,emotiva,mcintosh,rowland  are all making it and many more. The gan has made them much better. They measure very well.there are some high end classical d amps that are impressive.keep an open mind.enjoy the music

You seem like a good guy @mark200mph , but every time I read your posts I think I'm having a seizure........laugh

I have never heard the Atma-sphere OTL preamp but did hear the Allnic OTL preamp at my home and that was so amazing and surprising. Being a tube preamp, I never expected it to have such detail along with the beautiful holographic tube sound.

My current and past gear has tended to be on the ultra-detail level. I never expected a tube preamp (and the Allnic DAC too) to be the most detailed gear I ever heard (but unfortunately not own).

I currently have a Benchmark HPA4 preamp, and I think the Allnic sounded more detailed. Definitely sounded nicer overall.

Must be my old ears, but my 58 lb Spectron musical MK lll class D amp designed by John Ulrich, it's output is 500watts@8ohm 650@4ohms and 1,200 watts@1ohm  sounds pretty fine to me, and brings my Maggie's to their knees I think my 30 year old ARC LS15 tube pre amp helps that i have mated to the Spectron I just love that unadulterated power
