I've owned a pair of Studio 60's for over a year now. They have been driven by a Denon receiver, a NAD 2400 power amp, and B&K AV6000 multi-channel power amp. With the separates I used both a Rotel and a B&K A/V preamp. I wanted something that was involving and enjoyable to listen to on a variety of material (from classical and jazz to rock). Ultimately, I found the B&K pre- and power amps to be the best match for the Sudio 60's. Although I haven't auditioned them, I would suggest that you listen to the Odyssey Audio Stratos power amp. And, as I always do, I encourage you to audition several pre- and power amps before making a decision.
