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

If you want the system to work well with tubes, the first thing is to sort out if the speaker is OK with that. Take a look at

If your speaker is designed to work with amps that are voltage sources (Voltage Paradigm) you will do a lot of struggling to find a tube amp that will work with it.

Good Luck!

You need not go to Canada for Psvane & Shuguang tubes.

*actually i have a difficulty to match speaker systems with*

Well, what ARE your speakers? That'd help a great deal to make a recommendation. But in general, for "lush" sounding tube amps, I'd say start with Cary, &/or VTL....."vintage" means something too, sometimes older tube gear sounds more "tubey"......

thanks for many tips and knowings, everybody.

my speaker system is 'dali hellicon 800' - 4ohm needed 400watt amp power.
power amp is 'mcintosh 275'
preamp is 'jeff rowland synergy'
source is 'dynaco pro'

some said 300b amp will be the best for 'warmth'
but i'm afraid that it won't be enough to drive power hungry speakers like dali800 or b$w 802.

anybody objection to use chinese shuguang kt88 tubes for better warm sound?

thanks again

Your speakers aren't a good match for a 300B SET amp.
