in my search for an affordable, quality power amp to run my old yorkville YSM1s i have narrowed down to the Hafler p-1500 (or maybe the p-1000) and the ART SLA-1. The SLA-1 is the recommended match for the YSM1s (made by the same company, duh). both have had good reviews. any suggestions either way? i might also try to repair this old bryton 3b up for sale in my area. anyway, help is always appreciated. thanks. -matt btw, still got an eye out for the Crown d-150 suggested to me in my last (deleted) thread.
