Smitty

So, I have Klipshorn's purchased in 2000. I have a Marantz 2380 (I think) integrated amp from the 70's working fine. I have that feeding my Marantz 108 (I think) power amp. Its sounds great. I have a large room, 40X25 with pine floors and wonderful corners for the KHORNS. However, I have read tones on getting tube amps because they sound richer and warmer (as I am told) But a McIntosh 275 casts 7-8 thousand dollars. Lately I have been reading a lot about Decware Zen single ended triodes. They are supposed to sound great on an efficient speaker. The Khorns have a 105 db. But then I get to reading in forums all this other stuff and other opinions and technical stuff and I get lost and confused. I just want to get tube amp that I can afford and is rated to sound excellent on my KHorns. Can anyone give me some easy to under stand advice?
