SF upgrade of SFD 2 to Mark III status

Sonic Frontiers will still upgrade their older SFD2 to the newer Mark III for $1300. SF says it sounds better as well as having better current capabilities. Has anyone actually had this upgrade done and care to try to describe the improvement. I also understand that the upsampler that they recommended is no longer available. Any ideas.
Hi Denny,

Had My SFD2 Series 1 updated to Series 3 almost a year ago. Well worth the dough! Many moons ago, I auditioned a Series 2 Dac against my piece and found that the principal change (addition of HDCD capability) was not to my liking. Yeah, it sounded better playing the few HDCDs in my collection but worse on everything else. Word has it that those first generation PMD filter chips, through which all signals were routed, really weren't all that great sounding. Well the latest PMD filters work just fine thank you. Principal differences seem to be a sweeter top end and a further reduction in sonic grit from the Series 1 Dac. The already quiet noise floor is quieter still. Sonic Frontiers has also incorporated some cool user cofigurable hotrod features. You are able to alter the degree of dithering and you can overide the HDCD mandated 6db reduction in level of non-HDCD material. The latter trick improves the Dac's dynamics on said material. As far as the Upsampler goes, I have one but don't use it all the time. If you wanted an upsampler, I may be able to help. I think I can get my hands on one. Highly recomended. Even with the used market as it is you couldn't score this level of sound for that small an upgrade investment to your existing piece. Let me know if you'd like some help aquiring an upsampler.
Better hurry SF is going out of high end 2 channel biz and concentrating on Anthem HT. Too bad Paradigm bought the company so they could sell more mass market spkrs to all the Vidiots out there.
Had the upgrade about a year ago. The cost is $1300 but you need the D2D-1 (700) and the cable ($50) also to get the full impact. The upgrade made a substantial improvement in high and low end. Better definition, better detail, and better micro dynamics. Upsampling really works.
