Tube sites/books, recommendations please

I would also agree with the Brent Jessie recommendation. He is very helpful and honest!

Lensteve - what's the rest of your setup like? (Sources, power amp, speakers, cables, room dimensions, etc.)

Also a note on McIntosh - While I like their products and believe they're built extremely well, it's next to impossible to find a truly good deal on anything they've made. I wouldn't try to build the entire setup around McIntosh gear unless you can just throw around thousands like it's pocket change. A good idea would be to try to find someone in your area who's got a tubed setup and get to know them. Out of my tiny audiophile circle, I'm the only "tube guy", but my dad had tons of Mc, CJ, Fisher, Dynaco, and some older Citation amps.

Currently my setup is as follows:
Sources-McIntosh MVP-871 and Oppo 83 Exemplar edition
Power Amp-McIntosh MC2255
Pre-Amp-Utilizing my NAD T-765 Receiver via preouts (hence me purchasing pre-amp)
Speakers-Golden Ear Triton Two
Interconnects and speaker wire-Paul Spietz anti products
room dimension is 15'W, 12'Deep, 10'H

You can probably get plenty of juice from a ~35 wpc tube amp. I still suggest getting used to the MC2255 and find some nearby audiophiles to let you check out other pre's in the meantime. How do you like the Triton Two's? I auditioned them a while back and was underwhelmed, but my dealer didn't take much time setting them up and I'd just finished listening to Magnepan 3.7's. I kinda think the setup and quick switch didn't do them justice.

I couldn't be happier with the Triton Twos. I've had them for over 6 months now and they still bring a huge smile to my face. It took me a little while to really dial in their positioning and the volume level of the dsp that controls the bass, but the soundstage is breathtaking and the detail is phenominal. The Maggie 1.7's was one of the many speakers I auditioned and it wasn't close for my ear. The 3.7's weren't in my tax bracket...lol
