Tube for BAT Pre-amp


Hi, I just got a BAT Pre VK-30 go with my Classe amp. How long does it take to break-in? What am I going to expect after it breaking in it is pretty warm right now and also laid back and the high is not extened enough midrange and bass is very good so far? Is this going to be the sound even after breaking? If it does is there upgrade tube I need to replace from stock so it does make the sound come forward and high extened more. Thanks for any info.

Tube roll that baby! I have a VK30 too, and found the best results with Amperex tubes. Let me know if you want to try some, I have a bunch for sale. (Bugle Boy 6DJ8s from the 1950s). I think you find much better and more dramtic results with tube rolling than with any cable swapping, IMNSHO.

Skip all the above and start saving for the SE upgrade. You will not believe the difference! The SE upgrade will transform and make a huge change to the sound.
Can any one tell me how to set-up home-theater loop pass through in the bat pre-amp? thanks
