i had a pair of arc classic 150 monos for quite a few years before getting a pair of vpa. 50 watts is not an issue as they seem to have as much as the classic 150 monos, they are vastly superior in every way mine are driving apogee stages with ease, replacing jm lab mezzos. What has just made a worthwile improvement was using a shunyata hydra 2 with audience powerchord. the vpa are special and may be the last you buy.
