I just scored a set of 1983 Cornwalls on Craiglist for $150. I have been looking for a pair of these locally for years. I like to listen to a variety of music from Classical to Hard Rock. Right now I have a MAC 1700 hooked up to them and they sound pretty good. I plan on rebuilding the crossovers soon because they are original. I have a Marantz 2245 that needs recaped (does not work yet)and I have enough parts to build a tube amp. I was wondering if the tube amp would be able to give the "punch" that the hard rock needs to sound good. I don't hear of many people listening to such music with tube amps. I have a set of Heresy's that I did try a tube amp on, and the sound lacked "that punch". Please excuse my inexperience. What direction should I go.
