I recently took delivery of a Raptor and it sounds great. I know this is not the first thread of this kind but there must be some new users/info out there. What tubes are you using and what headphones seem to have synergy with your tube choices?

I have a Raptor and what I have been told is the 12AU7 should be a Telefunken while the 5687 should be Tungsol. I have found the Telefunken but haven't been able to find the Tungsols.

Tung-sol 5687's are very readily available on EBay, and are not hideously expensive, with a matched pair going for $25-30.

I bought a pair of Tung Sol 5687s on ebay for about 25 bucks and also some RCAs. I have an RCA 12AU7 as well. Can you tell us how the Tung Sol Drivers sounds as compaired to the stock tubes? Also, what headphones are you using?

 

[GordonFreeman]

Surely there must be some folks out there who own a Raptor and tried some tube rolling.

Tungsol 5687 are the best for Raptor. I also liked Mullard 12AU7 (CV4003) - really gave a nice euphonic sound as the Raptor is not very "tubey" to begin with.

Which cans did you make those conclusions with?
