classic. in its day it was the consesnus best preamp.Not likely that it could compete with todays preamps. I think you should keep it un-modified. You have got a piece of audiophile history. Mate it with an ARC D79 and say a pair of quad esl 63 and entec subs.
Is Audio Research SP-6 considered a good model?
I'm trying to decide on how to replace my Plinius 9200 with separates. I have a 70's era SP-6 and I'm wondering if it's worth servicing and keeping, or are there other tube pre amps (Audio Research or otherwise) worth looking for used (1-2K range). Also have a AR D52B that I will definitely be replacing.
