Amp for VR4SR

Thank you Ejlif & Tvad.
Talking about power: did anyone try the VR4SR with a set of Jeff Rowland mono amps? In my experience (not with the VR) they have lots of power - very clean and accurate. I consider Valves because I love the warm sound, although like also lots of details and excellent sound stage. But if these pair need lots of power than maybe a set of Jeff Rowland as the power unit + a valve pre-amplifier (vac, cary, lamm ….?) will fit the most?

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.

Thank you Mdrummer01 and Mmcghee
since this is a class D Amp, Did you also checked nuforce and/ or CIA?
