Hello
@Ron Resnick. Actually, I think my power started out pretty good, with about 10 homes on this leg from the trans. and 200 amp service in copper to my panel.
And got better: I pulled a dedicated 10ga. run of THHN in conduit. A TT7 is plugged into a Shunyata Z1 outlet via a Sablon King pc. Everything goes into the TT7.
Due to a combination of laziness and a bum knee, I have not yet pulled the 6ga copper cable I have for a dedicated run for the audio system. That would significantly lower the impedance of that run. At 35' the benefit to voltage drop would be minimal, IMO.
In short, I have no power concerns and the system sounds great. That said, anything worth doing in audio, is worth over doing, in all likelihood.
The concept of being off-the-grid is appealing theoretically, and I would like to see if it is in practice, ergo the consideration of the baby Stromtank.
Since I would only put the front-end on battery power, I would target the smaller 1000 unit, and probably want to put the MSB dac on that.
To your specific question, I have no idea how the MSB Reference would be on battery. I have posed that to MSB, but have not yet heard back. I expect their answer would only apply to MSB and we would have to test the other dacs...but why wouldn't it help any dac? Seems like it would, but it requires validation, IMO.
I am wondering about the potential power "improvement" to SQ by adding the Stromtank vs. the DD. Depending on the Stromtank model vs. the Reference DD price, the Stromtank could be cheaper. Funny that the Stromtank might actually be a bargain.
I expect, and with no hocus-pocus logic at all, that MSB would still tout the benefits of the new FPGA processing as being a net-plus to SQ even *if* the power aspect was a draw.
I think given these multiple variables, an in situ demo would be the only way to possibly draw a practical conclusion for my (or any) use case, regardless of the theoretical expectations. In any case, it would be a fun experiment. I can follow-up if an MSB reply is useful to the community.
We *need* more details on the DD configurations and usage, that's for sure. And I need to get that cable run!
