Vac Phi 200 vs. Audio Research Reference 75

Hello all,
My Lectron JH-50 (EL-34 tube amp) may be dying and if I have to replace it, VAC Phi 200 and Audio Research Reference 75 will be at the top of my list. I plan to check the Reference 75, but I have no ways of getting even close to Phi 200. The speakers are Pro Ac Response 3.8, the pre-amps are Klyne 7 and NAT Audio Plasma. I listen to everything but hip hop and modern country music. Acoustic guitar, piano, violin, woodwinds, and voices are my favorite instruments. I do play Black Sabbath once in awhile (and I am going to get their new CD). Please, reply if you have heard both of them or anything else that should be in the competition.
Thanks to everyone who replies.
