Seowfun,
Now it all makes sense - thought that I recognized your name. So glad to be of help.
The Bello stand is really is "Bella" (nice in italian) - it's rare to see wood and metal so nicely intergrated. Going to have to check that out some more. Looking at the pictures again, it's clear you took a lot of care to match the looks with the sonics and it really shows. The V4M CC is really rather tasty too. A little hard to tell from the lighting - is the finish Rosewood or Maple?
Back to tubes . . . Sounds like the MF tube buffer is a good place to start. You may want also want to check out the Eastern Electric BBA - my sources tell me that it is quite a good product and you can order it from the HK distributor (the HK Vaccuum Tube Club on Pottinger Street in Central). Pricing will likely be very good given the proximatey to the factory just over the border in ZhuHai. Check it out here: http://www.eeaudio.com/eeaudio_009.htm
Right now I am using the Primaluna Prologue 2 and the ACs sound very nice indeed.
If you ever get a chance go back to HiFi Tone, ask to hear the V3Ms with the Raysonic CD-128 and the MingDa 300B monoblocks - just lovely. Just when I thought it couldn't get better, they dropped in a matched pair of Shuguang 300Bs and it was sheer magic. I'm still drooling thinking about it :)! If I didn't already have far more equipment than necessary, I would have bought them (the MingDas w/ Shuguangs) on the spot.
Good luck and all the best.
Cheers,
Garry
