What's with BAT?

I love to roll tubes but 6H30 sounds excellent in my ARCs so I just enjoy the music.

My experience is similar to rlb61.  The 6H30 implementation that I've heard/owned in various preamps much too close to a transistor in terms of sound to justify the downsides of tube ownership, at least for me.

I got tired of worrying about putting hours on the tubes, etc.

The 6H30 certainly is in vogue however and there are many who love them, I simply wasn't one of them.  I guess I'm just a SS guy when it comes down to it.

What is THAT?

I'm currently auditioning a phono stage that is running (3) 6922s and has a switchable high output of 72db/MC stage.

Any recommendations for musical and quiet tubes? Any variant?

What is your source for the Seimens?

Hello, slaw- Generally speaking, it seems most that use the term, "musical", are referring to tubes that add warmth to their system. Siemens won’t. The early to mid 60’s, grey shield, internally date coded, CCa is a very neutral/clean tube, with beautiful extension(in both directions) and great sound stage. The later ones(CCa’s), with the silver shield, can be kinda zingy on top(for my tastes), but- most everything else is still there. Mullard and Ediswan made 7308/E188CC tubes that will probably fulfill your desires/tastes, if you’re looking for warmth.  Amperex, a bit less warmth than those two.  Just be certain to ask for tubes graded, "low noise". I bought a number of excellent Siemens tubes(mostly E188CC & CCa) from this guy, back when he had them: (http://www.ebay.com/usr/audiotubes_de?_trksid=p2053788.m1543.l2754) I haven’t bought any nine-pins in a few years(thankfully, given the current price of my preferences) and can’t find a link to the other sellers. One was in Argentina and it took the package of CCa’s 6 weeks to get to me. Yeah, I was sweating! Upscale Audio tests and grades their tubes for noise and a plethora of other parameters.
