I wonder what's happening in my implementation?
I have tried to elicit more information about the transport and dac I'm using, but to no avail. All I know is this:
The transport upsamples to 96kHz
The transport communicates with the dac via I2S
The dac, it's suggested, reclocks (is that needed with I2S?) and plugs straight into the 4x 1704U-K chips. Presumably, with the I2S delivery at 96kHz, not much digital filtering is needed? Output stage is FET-based, balanced, class A, no negative feedback and independently powered (as is the digital stage and transport).
There is a digital filter in the dac but the manufacturers have anonymised it. (Normally the DF1704 is used with these chips - is it something else?).
The resulting sound is tremendously engaging and, above all, noticeably 'muscular' and resolute. It feels like the sound is sculpted in space, with no loss of tonal shading or timbre subtlety. The icing on the cake is that I consider the overall cost for the sound I have, to be, frankly cheap.
I wish more on here could hear it.
