McIntosh MC2102 owners past and present

I've got the itch to make a move and am interested to hear from past and present MC2102 owners on the following:
- How many years or months did you keep the amp?
- What speakers did you use it with... anyone try Harbeth?
- Did tube rolling pay benefits and which tubes made the biggest impact?
- How does the MC2102 compare to other comparably priced / powered tube amps?
- Did anyone try running their source directly into the amp and how did it work out for you (I have a cdp with volume control).
- Would you recommend this amp?

Thanks,
Paul
