Thanks to those that inquired - I am holding on to this amp as a benchmark for any potential replacement. If the new ones do better I keep them, otherwise this one stays. Looking at Krell, Aragon and, yes, Emotiva (spare me the hate for including the E brand here, but I like 'em). If I could find a pair of 600x2s that would be the ticket, but they do not pop up that often. Also considering a set of tube HF set with SS for LF. So a pair of Hurricanes would be of interest. If you happen to see something for sale that may fit the bill let me know. Thanks!
