    Default 6sn7 tube

    Looking to upgrade my Cary SLP98 preamp stock tubes (EH 6sn7). The EH 6sn7 sounds a bit edgy for my taste.

    Do you guys think the price is good?

    Thanks!

    I put a pair of these (http://www.ebay.com/itm/VINTAGE-USED...item4d08fffbb7) that I picked up NOS from a local collector and have no desire to change until their toast! I paid 150$ and unfortunately that was the only pair he had. He has since liquidated on epay!

    Thanks. What improvements did you get over the replaced tubes?

    To clarify, I'm looking for something sound open and transparent without being harsh

    +1 for the RCA VT231 (6SN7) gray glass for a nice warm sound.

    I tried the RCA VT231 last night but they are a but too warm for my cary slp 98. Any recommendation for other 6sn7, beside the Treasure CV-181, that are more neutral and transparent ? Thanks.

    I put a some NOS Telefunkens in my amps. Very quite, open, warm, detailed, etc. In fact, I'd say they're dead silent as input stage tubes. I bought them based on a review of 6SN7s I found that rated them the top 6SN7 in all categories. Not sure if the Treasures where included in that though.

    I have a pair of Black Treasures that I bought from Grant Fidelity for my Rogue 99 super magnum, but they dont fit under the lid (bottle is too tall) So I can sell them to you if interested for $125 shipped. They are premium tubes and come in the premium boxed case.

    They are a great, transparent, warm sounding tube. I had a pair in the same Wright wla 12a pre as THSMITH and they are worth the coin.
    PS: I'm still kinda new in the hobby, but my wallet has been around the block a couple of times.

    Hi Brian,
    Just about all the old 6SN7 I tried are warmer sounding than current offerings. I tried some old Tung Sol that were pretty neutral. The EH is the most neutral one for me so far but it does have a bit of an edge on some systems. The standard Shuguang metal base might be worth a try (cheap too). It's slightly warmer than EH but it's much smoother without the edge.

    Sorry, made a mistake. The Shuguang are regular base (maybe red, I think). I had the visuals mixed up with some Russian military 6SN7.
    Hope you enjoy them as much as I do. Give them about 25-50hrs break in. Keep in mind though that they are slightly warmer than EH.
