Questions about tubes and gear that glows. FAQ

RE: I voted for Neutrality.

I went through all the tubes everyone mentioned in listening tests over many weeks, using my Cary preamp as the 6sn7 test bed. It is a simple and good linestage preamp with upgraded parts to maximize its sonics. And after going thru the best samples from my collection of hundreds of 6sn7 types I felt that the most neutral sounding tube should be declared the winner. My reasoning was that if a tube highlighted some aspect of the recording in terms of better bass or better mids or treble, that should be considered a frequency anomaly, which is not what one wants in their amplification device. Consideration was given to dynamics, soundstage, and frequency response, and balance between all those points given the highest regard. And after going thru at least 25 pairs of various 6sn7 types and brands, in my system the RCA RED BASE 5692 was the winner at that time.
