I will offer a somewhat divergent opinion regarding the Stratos. I had one with the cap upgrade for a year driving B&W's. The amp was fine until pushed, somewhat warm and pleasant, always ran cool. At fairly loud levels however, the amp would lose control of the woofers and they would "break free" and become unstable. I ran some side to side comparisons against my Hafler DH200, this amp never exhibited this behavior. FWIW.
Odyssey Stratos, McCormack DNA 225 or Bryston4BST?
What would you buy and why. On the used market the Stratos is about 1/2 the price yet continues to get wows from the audio community. Would I be disappointed with the Stratos compared to a Mccormack or Bryston. I listen to all types of music use an Audio Research SP16L preamp, Myryad MDP500 G6 processor, and Dynaudio Contour 1.3 MK II speakers. Cabling is Harmonic Tech ProSilways, Truthlinks, and a Magic Link. Thanks for your experiences and input. Dave.
