@mapman - I have owned and liked an Odyssey Audio Stratos HT3 (with cap upgrade) - a three channel amp for the front channels of my combo HT/2-channel system since 2006.
Last September, the amp suffered a capacitor failure. So I sent (all 64 lbs. of) it in for repair and possible upgrade to Odyssey. For $900, I had the left & right chanels upgraded to full Kismet status, Odyssey's top line of amps. Sadly, UPS damaged the amp on the way back. Once that was fixed, I had issues getting my Vandersteen 2Wq subs with M5-HP crossovers to work together with the amp, which has a higher input impedance than the original Stratos. Apparently, an Audiogoner sold me a pair of the M5-HP crossovers which were custom made (without bothering to tell me this), and so they require different settings than do the standard M5-HPs. I have been working with both Vandersteen (Richard and Ray in the service department) and John Rutan of Audio Connection in Verona, NJ, to sort it all out, make sure the M5-HPs are working properly and properly set them for use in my system. They are on the way back from Hanford now. With a bit of luck, everything will be right as rain by the first weekend in June.
