Thank you MR. Smith! I can always count on you! In the middle of the night yet.
I have successfully cut it before with the DS Senior. I switched to new cables and isolators. I asked you because cutting it is like micro surgery. Very difficult and one false move ruined equipment. It has worked in the past. However I was never able to cut the ground. If I cut the ground the streamer will not see the DS. This is not only the DS either. It is every high end DAC I have. Plus the Ground is what really contaminates the signal AFAIK. I would have to think the isolators lift the Streamers USB power. Since for one thing it would then be additive to +10V. I am hoping/guessing they use the linear power in lieu of the streamers power. I mean I am hoping these things do not let the ground and power rail contaminate the signal. Since that is their big selling point. Plus to begin with streamer is not filthy PC. You know what though, it sounds fine to me.
The DS Senior is in my “little” system. Which is by no means little cost. It sounds great. The Select DAC II is in my reference system. I sincerely hope you outdo it with the TSS. For 30 Grand or so. That will be some feat indeed. It is possible since you and PSA cut all the fat. I will try it for 30 days when I can get it. If it beats the MSB I keep it and kick myself for spending Six figures on a DAC then. Although until TSS nothing could beat it.
Thank you again MR. Smith!
