Once and while, yes. But since 2007 I stepped into class D for curiosity.

Listening is definitely the key question to decide about liking or disliking HiFi equipment.
But as always when you learned about the insights of a technology, judgement will also take into account the technical beauty or uglyness.

I can't find where Courtice is. Google puts it as a street.

But I will have my TPA3116 at the Toronto diy meet tomorrow.

If you are interested and can spare the time post here to get on the list:

Greater Toronto Area DIY meetup

I was running it last night and had enough punch on the bass and enough "air".

It seemed to depend on source material. Bring your own ipod or equivalent and see how it sounds to you.

Call me crazy but I like Transistor Class AB Amps. There are some great low noise parts out there now and Audio OpAmps have matured. (And Class A when I feel like heating up the house and running up the Electric Bill.) Ha! Ha! To me, big Mosfets are slow switches which are better utilized in power supplies. The Switching Mode Welding Community is still undecided on FETs and Transistors, too; yet a linear transformer still yields the smoothest weld. I'm currently working on a SMPS for a Tube Amp, which will have the "Glass Community" up in arms but I think it's a great application for those those Mosfets that were originally designed and gated to handle current in power supplies with little Drain / Source Resistance; that is where they really shine. I think it's neat that we have so many choices and combinations to play with. What saddens me is the slow vaporization of "Through Hole" parts for us who like to tinker with electrons.

If any amp I've ever had actually had "Air", I'm not missing it.

If I'm missing something important, then how about posting some sound samples so I know what I'm missing?

Does anyone know of a place to upload audio files? I can upload something and people can listen to it as an example.

My favorite sounding SS amp is Accuphase E202.. Is it partly sound of transistors.. I dont know but would love this integrated DIY new built with out bass treble and all other switches on the front other than volume and I'd be in Solid State Heaven..

Hearing class D is on the agenda for this year..
