Top Ten Tube PreAmp of all time?

I agree with Sedond, this is silly. Due to system surenergy. Why this is so, you ask or don't ask. But the Bat 3i sounds great in my system, but for some unknown reason the Bat 50se doesn't.

Reprince is right. So far as the differences between the SP-10 and SP-11, certainly the 10 euphonized the sound more than the 11 which was more transparent and probably closer to neutral across the board (hybrid). The 10 with all tube power supply has the ability to make more music sound live without any loss of musical information, an ever lovin bloomer. It just pulls you into the music, you really don't care if it's ultimately accurate or not. Interestingly enough I have just done an extended listen with the 10 Mk2 in my system and with an upgrade in caps, wires and resistors it just might hold its own against the top tube pre-amps out there.

Tubegroover: I would not doubt it; my JP80 is a pretty old design as well, and I'm not selling it soon (I heard somewhere it was similar in circuitry to the ARC SP6, but with a much better power supply and point-to-point wiring). A friend of mine redid his SP-10 with silver wiring and had a great-sounding pre (don't know if he still has it). Not a bad product to buy used and try a few upgrades on.

I have owned an ARC SP10Mk2 for many years. It's wonderful, but it could use a bit more clarity. I've thought about upgrading the internal parts, but I would hate to destroy the original voicing, and also the resale value. I know Great Northern Sound Company can do extensive mods, but for the price, I could buy something state of the art used! Do you guys have any suggestions? Thanks.
