The main speakers I use w/ my 502A is a pair of Tannoy DMT10 Mk2 studio monitors. These are 94dB efficient thereby making the 60W/ch (I'm using KT88 right now) plenty. In this setup I'm using the 502A as an integrated amp i.e. CD to amp, amp to speakers.
I've also used my 502A with my Green Mountain Audio C1.5i floor-standers to very good effect. The C1.5i are 89dB efficient but the 60W/ch seems to be plenty in this case as well. I ran the 502A thru a preamp in this setup.
