Glenn, I have two 5687 adapters that came with one of my SP's but never got to try them yet.

 

I don't think 9pins can beat the 6SN7/6F8G's.

 

BTW I like the way you and xcalibur are making my tube addiction even worst!

I guess we will have to Waite till xcalibur does some more listening on this tube. I will have to look through my junk and see

if I have another 5687 tube.

I think you are right about the 9 pin not being able to best the octals at this point I don't even use octals anymore all UX4

tubes for me.

Best Power tubes are UX4/B4 I think.

 

The bottomless pit of tube addiction is becoming an abyss now!

I agree most of the 9-pins are nothing special.  The reason I was interested in trying it was because this particular tube is from a family of space age tubes designed for military and NASA use.  They are used in some very nice amps and seem to have come from a totally different engineering background than the commercial audio 9-pins like the 12AX7 and their lot.

 

From what I heard last night, I don't think it beats a good Tung-Sol, but I can think of a lot of other 6SN7 tubes I have listened to that the 5687 does beat.  If I had to bottom line it straight against another tube I would say it matches up to the Hytron 6SN7GT in overall ability except it has way better bass than the Hytron does.  Pricewise they seem like good value for the dollar to me.

I would have to say if there is a weak spot in the 5687 it would be dynamics.  Not in the note attack, that is not bad, but rather the actual contrast between loud and quiet notes feels diminished somewhat.  It sort of softens the whole presentation some which hurts realism a bit.

 

The tube is opening up a bit in today's listen.  The bass slam is reduced now but it became tauter in exchange.  I really like the tube's tonal balance, kind of a mix of Sylvania and Hytron sound even though this is a Tung Sol tube.  It doesn't sound rolled off anywhere but is balanced and mellow.
