What's the "best" tubes for a cal alpha 24/96dac?

I'm running sovtek lps tubes right now and am thinking of changing tubes in lieu of buying a new player if I can avoid it.

There was a period where the Brimar CV4004 was hot, but both are great. The Brimar are warmer on top slightly.

I'm using them in my Norh CD-1 and have had great results - more relaxed sound, less high frequency grain, better detail. These effects are subtle, but definitely there. Check out Joe's Tube Lore on the Audio Asylum FAQ section for more info and specific tube recommendations. Beez
