Supratek or Don Sachs - which way to go?

I have one of Don Sachs first preamps, since fully upgraded, but I decided to buy his new preamp, which accommodates the new WE6SN7 tubes that Don prefers and which has several enhancements over his current preamp.  His current preamp is far and away the best preamp I have ever owned (after CJ, HK, Berning, Modwright, Belles, McCormack and others I now forget), and the new preamp will no doubt be even better.  

Like Don, I think there is magic in using 6SN7 tubes in preamps and Don has it all figured out.  Same with the fine Supratek preamp.  

Greetings whitestix...and congrats on your new DS preamp...I am the proud owner of a New gen 3 Supratek Chardonnay pre...my Qusetion to you is how do you like the new  Shuguang WE6SN7 tubes?...I replaced the stock russian 6sn7 in my Chardonnay with the  Shuguang WE6SN7 and really like them ALOT....i went thru about 4 to 5 different combo's of NOS 6sn7 and foud the new  Shuguang WE6SN7  were more to my liking (although it was VERY close on 2 nos pairs In my system and with MY audio preference and ears)....just curious what you felt about the  Shuguang WE6SN7?...Did you try any other combo's? once again congrats on your new pre...which i was going to buy and it was a coin toss and sum ears i trusted to move the needle to Supratek(still may buy one to compare in my system...we now have 2 great pre's under $2500!!TRUTH)

@audio123 I bought a pair of the Shuguang WE6SN7 Plus tubes for my DS pre.  They are very clear and nicely extended.  Unfortunately I'm always trying to tame my accuton tweeters and they made me grate my teeth a bit.  I'm currently running Raytheon JAN's with copper support rods in the driver stage and RCA Grey Glass VT-231s in the buffer stage.  I could see how the WE6SN7's would be great if you didn't have the tweeter issues I've got.

Thanks cal3713 for a unbiased opinion on the  Shuguang WE6SN7..i was thinking about buying the latest DS pre to compare it to my new gen 3 chardonnay pre...well i am going to pull thr trigger in mid to late  november,,,,should be f---ing cool to have both and compare the 2 with my audio club...stay tuned...more chites and audio giggles coming

 Hey,  audio123, 
Please refresh my memory about what amp and speakers you are driving? Also, your digital side.  I know you went with the Tubador DAC. Did you consider the MHDT Orchid?
