I just bought this from a local and paired it with my Bose 901's, Series V - wow, just wow. Wagner's Ride of the Valkeries is just fantastic, as is George Harrson, Jimi Hendrix, et al. Greast amp, just now need tp figure out the purpose of the various cut outs - although my ear is workng the best for that.
