Whatever 12B4A's are in the Dodd are what Gary shipped it with. (I'm guessing your 12BH4 reference is a typo?) Yes, I'm sure my source has something to do with the sonic signature of my system, but then again... EVERY component in any system has a sonic signature! If you think about it, anything from a pair of I/C's to a Power Cord to a component can be considered a tone control. As always, it comes down to the ONE most important word in audio - SYNERGY. I wouldn't argue with anyone if they said the Dodd is actually a better Pre-amp than the Primaluna, but in my system, for my ears and taste, I prefer the Primaluna.
As far as the Rogue goes, there's not enough power for my Vons. Even though they are supposedly now 91db efficient (up from 89db before the upgrade) my VR-4 Gen.III's love the 300WPC giddy-up that my Moscode 600 provides. (You can even ask "rpf" Rob. He even said it about my Moscode.)
No doubt, active cross-overs are the better way to go in Bi-amping, but I didm't want to get that complicated with it. You know that I respect your opinion, but I don't feel that my QED speaker cables are suspect at all. (BTW - They are Silver clad copper, not all silver $$$) In the 2010 meeting at my place, the QED's weren't available because I broke a connector the day before the meeting, so we could only compare JPS Superconductor "Q"'s, Monster cable "home-brews", Audio Art SC-5SE's and Harmonic Technology Pro 11's. The following week once Scott fixed my connectors, I did a speaker cable shootout here again with Bob M and Tommy Mag (I think?) with my QED's "in the mix". Regardless of price, my QED's sounded the best.
I'd love to try VS speaker cable, but their cable would cost me more that the complete speaker overhaul that Albert did for me in 2012. (Not happening unless I sell a dozen houses this week!) TWL is my next planned comparison if I can get Pete to make me up a set!?!
Bottom line is just what you said... if I like it, that's what counts.

P.S. - I'll take Chianti!
