I've been listening to the Plixir Elite BDC powering my Chord Qutest since Wed at noon (my time).
If anything, you have undersold the improvement this brings to one's system! Wow!
* Deeper, wider, and taller sound stage. A more cohesive sound stage, as well.
* Spatial resolution is heightened, with more clearly delineated musicians present in the soundstage. But in an incredibly natural way.
* Low level detail retrieval is now outstanding, but without sounding analytical or dry.
* Tone color and tambre are vivid and also nuanced.
* The noise floor is, as you stated, so low that it appears to simply not exist; music just emanates from the blackness. And, I suspect as a direct result of that, the sense of scale and envelopment is vastly enhanced.
* Bass dynamics, texture, and overall information is increased. But also better control and nuance.
I have owned my Qutest for over a year and yet feel like I am just now hearing it for the first time.
I'm taken aback that a power supply could make these obvious, stark differences possible. And I was already using an Allo Shanti! The above observations are compared to that... and the Shanti is clearly better than the stock SMPS from Chord!!
Well, thank you very much for designing this. My musical enjoyment has increased greatly!
Anyways, thank you very much, James! You clearly know what you are doing.
