So, what other amps sound like the First Watt SIT-3?

I'd like to see your recommendations.

I have and love my SIT-3 amps. Just wonderful. My speakers are Avantgarde Duo XD and love the warm/sweet/3D laid back sound.

I was just wondering if anything else comes close.

Thank you so much!

Thank you for the link.

Any idea how available and how much those B-1a amps cost? Very interesting.  

2 ideas: 47 Labs Gaincard, Lavardin


if you say j kimura's 47 gaincard, i say peter daniel’s audiosector patek (which i have and adore)

brothers from overseas mothers :)
Thank you for your responses so far.
