Tubes - Top hats, and Tube socks

Top hats are very effective, but that does not mean it will sound better. In preamp tubes a smidge of microphony can lead to a sense of "air" and with dampers the midband can harden up. So try it both ways as every tube and every situation is different. Don't assume anything. We go naked here.

Thanks for the input. Are there multiple types of top hats or only one for each tube size/type?

I should add that this is for an ARC LS-7 with Amperex 7308's.

Miketw-only one size for all the small tube types. Kevin Deal is right--that's the leanness I mentioned. See if they offer a money back guarantee.

Thanks Rcprince for the input. Keven at Upscale is right. A tweak doesn't necessarily make it better, just modifies the sound. Whether it's an improvement is a matter of preference. I've been playing with all kinds of isolation devices, power cords, cones, and other kinds of tweaks. Today I put something under everything, and the sound was too analytical. More detail, yes, but less musical. So go slow and don't assume more is more.
