Mr. P

Sorry I have been away a bit and just noticed your post.
I have 2 sets of Heresy's the Hersey I's are the fronts of my HT system powered by my Pioneer VSX-815. While I do listen to them at times for music I am not sure there would much point in Bi-amping them though I have thought about using the pre-outs on the Pioneer to add an amp just to see if it adds a little oomph to the system.

My Heresy II's are currently hooked up to my Fischer X-100-C tube amp. I am not if I should/could use the tube amp to bi-amp them. The other option would be to put them back with my Adcom system. The 545II is the main amp there but I have a 535L that is sitting with a minor problem. I think that would be a real possibility though I am a bit ignorant on how exactly I would biamp this set up. My pre-amp is an Adcom 555 if that helps.
