Eric, Have you looked at the chip amps. They are getting quite rave reviews (see below for one) They list for $39 but can be picked up for $20-25. You could bi-amp your system for around $100. There are also tons of mods on the net that really do make this a "giant killer."I had the pleasure of listening to Ron's Norh last Friday. For $400 this is a nice tube. I have a Cayin TA-30 that was a steal at $550, but I don't think it's available anymore.....Colin
