Replacing The Stock EH 6SN7 Tubes For Cary SLP 05


Hi

I run a Cary SLP 05 in the following setup

Cary Audio SLP-05 Preamp > Krell FPB 200 c Power Amp > Dynaudio Contour S3.4 Speakers

The Cary SLP 05 gives me that "live" atmosphere and soundstaging but I find that brass and horn instruments are still on the bright and harsh side with the stock tubes. It could be the Krell power amp. As such I thought of tube rolling and trying out some 6SN7's to hopefully give me more warmth and I guess a more euphonic and traditional tube sound. I will look towards replacing Tube Nos. 3 and 6 or the balanced buffer tubes first, retaining the stock EH 6SN7's elsewhere.

My shortlist follows below. Your opinions on how these tubes may sound in the Cary SLP 05 vis-a-vis each other is much appreciated.

I don't have a Cary SLP 05 but have found RCA GT Gray glass from the 40's have a very rich midrange and well balanced from top to bottom. So far they are my favorite 6SN7.
I think the Sylvania will provide a ton of clarity which might not be what you need. I had them in my Rogue and took them out fairly quickly as they had too much energy. Your mileage may vary. The Sylvania GTB of mid 50's vintage may work better.
