Thanks Iloydelee21. Got it! I wish Conrad Johnson still made a SS amp under its own label, a true CJ. The ET-250s definitely has a tube signature to me. It's a fine amp, but it did not work that well with my Harbeths, which are laid back enough as is. I see McCormack as more of a great home theater amp, so effortlessly powerful and fast, but lacking that last bit of 'audiophile' resolution and definition. A marvelous amp in the right place. But no 350 substitute.Hi bgiliberti, sorry for lack of clarity. i meant to say that people who have heard McCormacks have agreed with what you said about them. This includes one dealer who had a pair of McCormack 750 monos that i was inquiring about buying, and he said 350SA was much better in exactly that area of midrange and clarity (and he did NOT have a 350SA to sell). Essentially, he lost a sale by encouraging me to look at the 350sa or beyond...and i thought that was a very good proxy, particularly as i have known this dealer for over a dozen years, and he has always seemed very forthright in all the years of business i have done with him.
PS: What are speaker cable jumpers (discussed above)?
