the best 'tubey amp - warm,smooth,liquid' ?

For those speakers and your goals, the bel canto ref1000m or 500m class d amps might work well. They are smooth and liquid sounding i would say though not inherently warm though results in that regard may vary depending on speaker and preamp used. I use an arc tube preamp with mine to very good effect in that regard.

Audiozen, please read my post more carefully.

I said you need NOT go to Canada.

Fact of the matter is, Trelja stocks Psvane and Shuguang tubes in the USA and ships from the USA.

You NEED NOT deal with Canada in any way, shape, or form.

Hope you now understand better.

Member Trelja is the premier vendor for Psvane tubes regarding price and service.

Don't put too much stock in what unreliable sources may say or write.

Audiofeil..my apologies..I stand corrected. "You need not deal with Canada in any way, shape or form?"..whats this?..Buy from America only? How racist!!..I'm certain that your Audio system has separates from Japan and Europe.
Besides, the Trelja website Trelja.net has no phone number listed and has no online order form and no product listings. Its just a blank white page with no descriptions whatsoever. Not very professional for a "premier vendor".

I'm sorry, but allow me to clarify, please. That is NOT my website. Not sure what that website is, other than to say it's not mine. I have no affiliation or relationship with any such site as Trelja.net, Trelja.com, or Trelja.anything.
