Which SS amp does sound the most warm of all?

You might try McIntosh, Sunfire, Blue Circle, Mark Levinson, Jeff Rowland Design, Conrad-Johnson, Clayton, and Meridian.

My short list includes: Mark Levinson 432, Conrad-Johnson Premier 350, McIntosh MC402, and Sunfire Signature Stereo Amplifier II.

Then you might want to use Cardas Golden Cross cabling to further warm up the sound.

You might also add Ayre to the list.

Good call Artar1. I've got Ayre's V-5x and it's smooth and warm .
Great sound. My dealer is suggesting I buy the new ayre phono stage , but it's a coupla g's and I'd rather spend that on a new tt.

Tube amp sound is not always 'warm'...

I like a good tubed amp because they tend to sound 'alive' and 'open', while SS usually sounds 'canned' and 'dead' to me in comparison. The music can just vibrantly burst forth from tubes, while transistors often seem to only grudgingly squeeze it out in a leaden sort of way. Just my general opinion (based on not nearly enough experience ;^), and not one to be applied to SOTA offerings I'm sure...

'Warmth' is a different question than tubes vs. SS, and too much warmth usually means a loss of transparency and speed no matter which gain strategy is employed. I'd stay away from either a tube amp or a SS amp that offers a sound too cool or too warm, but rather stick to pursuing a more neutral balance combined with high resolution and natural harmonic structure.

Plinius amps from SA 100Mkll to current SA 102 stereo amps. Hard to fault the tube like mids and highs.
