Supratek..Cabernet 6SN7 or Cabernet DHT

I am currently using a BHK Pre with the FW SIT-3 and wondering if anyone has compared the Supratek to the BHK ? Anyone paired the Supretek with the FW amps and can tell how they match up ? The SIT-3 due to its low gain need a bit more drive. 

Made the order, a DHT/6SN7 Cabernet will be joining my system in 3 months time, really looking forward to it. 

Just hooked up my DHT/6SN preamp.  Listening thru the 300B tubes now.  Not even warmed up straight out of the box it sounds good.  It is larger than i thought with a separate power supply.  Definitely a nice looking preamp. Have about 2 hours of listening on it.  I have been listening to Don Sachs preamp.  

Will report back after about 300 hours of play time.  Gonna have to alternate with the 6SN output.  

I'll be very interested to read your thoughts on this preamp. Also curious about any experience you have rolling 300b tubes. 

Sent Mick a mail inquiring about my pre and if he had started on it yet, unfortunately there are many costumers in front of me, so this will take a while, he is doing his best to clear orders, but he had no time frame on when my pre would be finished.
Hopefully I will get it for Christmas....
