I have the Jolida 502 and it drives my Ushers effortlessly. Has a nice smooth mid range that was a must for me. When I seperated my 2 channel from my home theater system, I needed something on the 2 channel side in a amp/pre combo or an integrated. Started checking and I realized that I could get a nice tube setup. Now I'm thinking about getting some nice floorstanders as my next upgrade.
