What is the best solid state amplifier you have ever heard?

Most of us will never know how good (or poorly) our amp sounds because of the components that send signal to it

I have Audio Alchemy DPA-1 which receives signal from my Oppo 105 with upgraded LPM, an Audio Alchemy DDP-1 + PS 5 outboard power supply, connected via top quality Coax. Speakers are Emerald Physics KCIIs, open baffle. It is quite an enjoyable system 

A friend brought over his laptop with a few demo quality recordings and a TOL cable.  This configuration bypasses the 105 and the preamp/dac. My jaw dropped. It was no contest. The resultant music was stripped of all artifacts, transporting me extremely close to the recording. 

Huge fan of the Mola Mola mono blocks!!!! Super transparent.

I think that my 2 McIntosh MC2300's have the best sound that I have heard.

I built a Hafler 500 in 1977, I think.  Still running strong!

Cheers!

My Merrill Audio Veritas monos hit all the high marks for me...love them!!!
