++1 for Terry's heads up on the updated CODA S5.5, should've named the S5.6 to mark the improvements. I purchased without hearing it, though I also got confirmation from Mike Kay at Audio Archon who is an excellent dealer.
The S5.5 is simply the best solid state amplifier I've ever heard with gear that I know. It's 50 WPC class A (more in A/B), very high current, and to my ears near perfect. I think Terry is a straight shooter, means to do well, and likes to share gear he is excited about.......I respect that.
