6922 tube question

I have a preamp which uses two 6922 tubes, currently Sovtek. To my ears, the sound is overly warm and the bottom end sounds bloated. I'm wondering if anyone can suggest a tube, 6922 or otherwise, that will clean up the sound.

I'd like a crisper, more neutral sound while maintaining strong lows (though not bloated) and extended highs. Any thoughts are highly appreciated.

Also, how long is recommended for tube break-in?

I second the Siemens. Also an Amprex 7308 would get you what you want.

Of the dozen or so 6DJ8s I have personally experimented with in preamp application, the Siemens 7308s ae my favorites. But, for the price, the Siemens 6922s and Amperex 6922PQs are hard to beat. Joe's Tube Lore at AudioAsylum's FAQ is a good place to go for reviews of tubes of this size.

I basically agree that the problem you speak of is probably
not the fault of the Sovteks. Make no mistake that there
are better tubes out there. If you haven't spiked your
speakers or used some resonance control with your componets
you may find that doing some 'tweeking' may really help.

Before you experiment with tubes try a different (SS) preamp and see how your system sounds. The Sovteks do not in any way sound the way you've described. They are not warm! They're bright and harsh. There's more going on here than tubes.

For lots of detail with good to great bass go for NOS gold pin Seimens and for good detail with lush mids and great bass go for NOS Telefunkin Falcons! Can't go wrong with either tube, considered some of the best!
Happy Listening!
