Tubes for Audio Research LS-15

I recently bought a used Audio Research LS-15. I love the unit, but I am interested in upgrading the tubes. Any suggestions?

You can contact Upscale Audio (website is upscaleaudio.com) or thetubestore.com for recommendations and purchases. Also, there is currently an auction of some good 6922s on Audiogon, I think they are Siemens too. How do you like your preamp?
