Cool 2x6. I have been really happy with my MK III though I have not used it as a preamp. It has been very reliable. I have used the MK III for late night listening with headphones the past year, used almost everyday on average 2+ hours a night. Still on the original tubes! Very nice product and has excellent build quality.

I would recommend purchasing the MK III from the authorized dealer DavidZheZhe on ebay.

Good luck with your purchases.
