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

I’ve only owned 4 or 5 ss amps (and heard a couple others in my system)...but my current Wells Audio Innamorata Signature has worked and won out for 3 different speakers. I’ve always thought that must something. Cleanest most natural of the rest. 

Vitus SIA-025. An integrated amp too. So incredible that I had to purchase it despite it being 100% over my budget. 

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.
