Hi Mboldda1, did you ditch your Consonance cybers? Curious what tube amps people have tried successfully with the 6381's, as they are either a hard load or just voiced for SS amps (or both). I haven't yet demo'd any tube amps, mostly because of the above assertion by Usher, and that realistically powerful tube amps are pricey and I don't have the kind of cash to buy a "demo" (no dealers around here either).
I use a Shindo Aurieges L preamp, a very good pre in its own right so I don't have a desire to try other pre's besides the P307 WITH the r-1.5.
