Thanks everyone for your comments and suggestions. I recently purchased a used Coda Model 10 amp. It offers true balanced input, which matches well with my new Balanced Audio Technology VK3i. And the tech support from Coda is awesome. I recommend to anyone who is looking for a extremely well-built solid state amp at a reasonable price to look at their line, at http://www.coda-continuum.com/ I haven't had it in the system long enough to compare to my previous amp, Counterpoint SA-100. Hope to post some notes in the near future. Next issue is whether power cords or bi-wiring will make a big difference. Any thoughts?
