First, I can echo everything said thus far. Jolida is built rock solid. Over-engineered is the thought that comes to mind.
I was about to buy one of their hybrids (as the 1501 RC is) and had a long talk with Mike Allen. I am lucky enough to live about 5 minutes from Jolida's headquarters.
Mike told me that while you do get some of the smoothness of tubes with the hybrid (tube pre's and MOSFET outputs), it is just not quite the same as a full tube amp. I decided to go for the low-powered 102b (full tube - $580.00) amp. I am IN LOVE with it. I will NEVER go back.
If you are into rock, for instance, you might like the 1501 just fine. Lotsa power and punch. But if you are going for the pure, secuctive valve experience, give special consideration to the Jolida 302b (for just $200 more than the 1501rc) which will give you the power and full tube bliss.
Actually, for the same money, I would go for the 202a over the 1501rc. Don't be scared by the lower watts output. Tube watts really are different. If you have 88-90db speakers (moderate efficiency) you will be fine.
Basically, you are giving up better sound for remote control for the same money. How could you sleep at night? :)
At least audition the 202a (and the 302b) before purchasing the 1501rc. After hearing the "half-way there" tubiness of the 1501 vs the full deal, you just might kick yourself for not going all the way.
Big picture, tho, you can't go wrong with Jolida. I congratulate myself for going "out on a limb" (at that time) and making the jump to tubes every time I listen to it. I will never buy another solid state amp again.
