Cary slp-05 tubes rumor or fact?

If the openings on the SLP-05 for the 6SN7 tubes are as I would suspect the same as on an SLP-98P they will not fit. No more than a 1/16 of an inch clearance for a standard tube base. Cary designed them for estetics so the tube is seen not the base. The sockets can be swapped out (and upraded at the same time) to be flush with the top of the pre so you could use the black treasure tubes but if you cant perform it yourself it would make trying the tubes more costly. I doubt very much if its a matter of removing the stand offs in between the socket and the top of the pre without actually changing the socket for its different mounting design.

You could try to purchase an "Octal saver" which is an adapter that would raise the height of the socket. Not sure how deep Cary's sockets are so you might not be able to easily retrieve the adapter once you put it in place. Good luck.

The spacers may give you the ability to try the tubes but how would you ever know the real gain of them by adding another large connection that surely would have some negative effect.

Has2be has a point BUT I'm betting you will know if the tubes are better or not even with the extra connection.
Tyi them with the sockets. If it indeed sounds better, you could consider something more drastic as Has2be suggests also.
If they don't sound better, don't even think about if it's JUST because of the sockets (it won't be), sell the tubes and move on.

I'm curious as to why you are so anxious to try new production 6SN7's given that the 6SN7 is one of the few tubes for which there are still tons and tons of excellent new-old-stock available at reasonable prices. The better production out of Shuguang is indeed good stuff - I'm not trying to diss the Black Treasure tubes - but it hardly seems necessary.
