Thank you Amirm! I didn't plan to have matching components it just ended up that way over time. Before the Sunfire preamp I had a Counterpoint SA-5000 and before the Carver cd player I had a Denon, a Sony and a Adcom. Now for Tom's question about tubes I have three Amperex PQ 6922's in the linestage, 2 Telefunken 12AX7 smooth plate and 1 Amperex Bugle Boy 6DJ8 in the moving magnet section of the phonstage and 3 Sovtek 6922 in the moving coil section (just to fill the sockets my Grado Reference Master 1 cartridge is moving magnet). My cd player uses two Amperex orange globe 6DJ8's. As for nirvana yes I am quite pleased. In my phonostage though I am split between the Telefunkens and the Sylvania triple mica black plate 5751's (thanks again Tom). They both offer something different but very pleasing.
