Amp for VR4SR

Thank you all.
Most of the audiophiles that I made contact with are sure of 2 "basic facts":
One - the VR4SR LOVE valve - as if they actually made for it.
Two - they do need power.

So it seems that I need to check and listen to either strong (and unfortunately expensive) valve amplification or the combination of a "gentle" solid state power amp(maybe Jeff Rowland? I wonder if pass labs will not be too "cold") with a valve pre-amp.

Using hybrid as an amp (with valve pre amp) sound very interesting although I must admit that I never heard about Moscode until this thread.

Since I am located about 10 hours flight from the US I assume that home trail will not be so simple to arrange....
and it seems there is no dealer around.

I also use the Spectron Musician III SE MkII with the VR4SR MkII's. Results are excellent. Albert recommended this amp when I purchased the speakers and I appreciate his solid recommendation. I have not identified any weaknesses with this amplifier, a first for me. The praise for the Spectron is well deserved from my perspective. Speaker cables are Acoustic Zen Double Barrel and IC's are balanced FMS Zero's. Preamp is Audio Research Reference 3.
