I would have to agree with Rgd on the Sonic Frontiers SFL-1 or SFL-1 Signature. After owning one of these gems and putting a good tube in it they are very hard to beat for the money. I have to admit that it had an amazing soundsatge , good depth , and very very nice tonal balance. For the used price in $550.00 to $700.00 range this is, as it was called back in it's day "A Giant Killer". Excellent bass signal and very natural highs when matched to the right amp. You can buy it and re-sell it for the same money if you don't like it. They stay at the same price and are always looked for by others......Good Luck !
Best Used Tube Preamp (under $750)?
I need a used tube preamp under $750, and am having trouble deciding which. I have yet to listen to these, but the price has determined these suggestions. Audio Research LS7, Sunfire Classic Tube Preamp, Rogue Audio 66, and that's all I've found so far. If you have an opinion of one of these, or a unit I haven't mentioned, PLEASE post a follow-up. Thanks all.
