For the gentleman who said “sounds like stock tubes to me” I am using some Nos Telefunken 12au7’s from the early 1960’s that transformed the preamp and made a huge improvement. I fully realize the benefits of good, nos vintage tubes from the 40’s, 50’s & 60’s and maybe even the 70’s. What concerns me about the Supratek preamps is the return policy. I’ve read Suprateks return policy and understand it’s a 3 day return and the customer pays the return shipping ($200.00 in my case) and you get your money back only after he sells it. I doubt if he sends you a fully broken in preamp which makes the 3 day return policy basically worthless. I don’t doubt you’ll eventually get your money back, everything I’ve read about Mick says he’s a very reliable and trustworthy person, it’s the amount of time you may have to wait that is a little concerning. It may take a week or two, it may take a month or two. Compare that to the linear Tube Audio’s return policy, first of all they fully break in all their products before they ship them, they give you a 14 day, no questions asked and they even pay the return shipping. What more could you ask for? The biggest and most important question though isn’t about a return policy, it’s about sound quality in your system and synergy with one’s equipment. Not an easy decision.
