That is certainly sound, not to mention practical, advice. Having read a lot of threads in the past few days, as well as the helpful responses to my own, I think what truly intrigues me the most right now is trying out a good tube pre-amp. It seems that the Joule is in my price range, and I have yet to read a bad word about it. Unfortunately, none are available in the used market currently. In the meantime, I can certainly play around with a new amp, using my integrated as the pre, as you suggest, until I find a good deal on the Joule or some other tube pre-amp. I wish I were as patient as I expect everyone else to be with my "novice" questions.
Thanks again.
