Kschiu: Sorry about the jump in price on the 5751. That sometimes happens when there is a frenzy with auctions. If you can find a good deal on a GE or RCA pair, the triple mica might also work out well. I only compared the Sylvania and the JAN to the various 12ax7's I had and the Sylvania was significantly more full-bodied and clear compared to the JAN in the CAT JL-3 amps I was comparing them in.
Concerning the use of a tube line stage in "bypass" mode for movies, I am in full agreement.....it makes no sense unless you can do this with the line stage powered off. I contacted a few preamp companies about this exact feature and I got the same answer: their product needs to be powered on. The new Aria WV that I have had for two months is the first tube line stage that I am aware of that defaults to bypass mode when powered off.
