Esoteric DV-50: Tweaks, Up-sample settings, etc.


Hello All;
I would like to hear from DV-50 owners out there who have fine tuned their units with various powercords, isolation devices or stands, EMF/RFI tweeks, cables etc. Have you found an Up-sample setting that seems to work well, most of the time, with all discs? I have found that some older discs do not benifit from up-sampling. Are you using the single-ended or balanced outs?
I am currently using the XLR outs with HMS balanced cable, but the gain is super high.
What is the consensus on the ground wire hook-up?
Are most of you using it, and if so are you grounding to the pre-amp, amp or to the screw on the receptacle cover plate?
Leave the unit powered up all the time? Shut down occasionally?
I really appreciate, in advance, all of your input regrding these subjects.
Thanks; Tim

Kana813 has a good point. Shipped mine off to Great Northern Sound Co for them to play around with and mod... On its way out was around 60% on for redbook performance against my Spectral SDR 2000/3000 reference, came back and gave about 80%-90% depending on the disc. Add the fact that it plays SACD and DVD-A with stunning results, one great piece of equipment...
Talking about XLR interconnects, MGOTTLIEB, he mentioned HMS and Purist cables. It seems that HMS is hard to find and the Purist cables are quite expensive. Has anyone heard the Esoteric DV-50 with the Siltech SQ88s? Are there any other recommendation with cables to bring out the best of this unit?
Yep, I am.  Mine went back for a new drive not that long ago and it's STILL a killer player IMO.
