Hey Balmer, I have two Cary CAD300se amps running my Khorns. I've run them with an Anthem pre2L preamp (low price-good value) for 2 channel. I have a sunfire tgpII for HT that sounds really, really good in 2channel and in 5.1. I have tried them with a Rotel SS preamp also. All three preamps have a different sound, but none of them are "in your face". I have the alk universal network, but am running everything else stock. I have run the khorns with a Bryston 4bst (a very good amp) and a Rotel 1080 (?) amp both around 200+ wpc. They both sounded pretty good as well but I did get that annoying intensity (best I can describe it) from them at high volumes.
With the Cary SET amps it sounds so much better. Hard for me to verbalize, but just more enjoyable to hear. When the beer gets to flowing and a good song (AC/DC live at Donnington castle-DVD, to name a few ) I have been known to turn them to full volume and they sound just as good, and very, very loud. Dont want to do that for too long (HUH!!!), but you can! Anyway I am by no means done experimenting but really got lucky with the cary amps. Got both for 2 grand. I did try an anthem amp 1 with them but like the cary's better, although the anthem sounds better than SS amps. Hope this helps.
