Best tubes for ARC LS16 preamp

The LS16 uses four 6922 Sovtek tubes when originally shipped from the factory. This is one of my least favorite tubes among the 6DJ8 / 6922/ 7308 variety.

What type of sound are you looking for? Do you like the tonal balance of your unit with the Sovtek tubes, or would you prefer a more linear, low distortion sound?
Or maybe warmer and more romantic. You could also have very fast with an extended and greater detailed top end.

NOS tubes are capable of providing all of these personalities. Vote on which appeals to you and I will give you suggestions to try out.

Hey Albert, while your at it how about listing some for my LS-15. I'd go with fast, clean top end. I like mostly rock music. Thanks in advance for any advice you can give.

THANKS FO RTHE RESPONSE,I PREFER A VERY DETAILED HIGH END,LOW DISTORTION WITH A SOUND LEANING TOWARD THE WARM SIDE.HONESTLY DON'T KNOW WHAT YOU MEAN BY LINEAR ,I'VE HEARD THE TERM BEFORE ...THANKS
