RE: usb to spdif with BNC-Yes

Hi,

> Yes the Musiland quoted by Thorsten has a 50R BNC!

Precisely.

And it has about 2" worth of appx. 300 Ohm effective impedance wiring connecting it to the PCB, 90 Ohm source impedance before the transformer, incorrect levels and a transformer that is rated only for 7MHz and where no steps have been taken to adjust the circuit to allow wider bandwidth and thus horrible SWR at higher frequencies.

I included that one for several reasons:

1) To illustrate that the presence or absence of BNC connectors is meaningless as an indication of quality of the converter design.

2) To see if anyone was paying a minimal amount of attention.

3) To see if anyone would claim that changing the connectors on this "broken by design" piece of device produced marvellous improvements in sound quality.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
