Marvda1,
I won't be able to offer any comparisons, but if all goes as planned, I'll be listening to the Response 3205 through my 86db 4-7 Ohm Vandersteen 2ceSigs on Tuesday. If you think it would be any help, I can let you know how the 3205 managed them when I get back from Endicott (home of Response Audio).
