SPDIF to USB converter???

Thanks Al, I'm actually on the verge of buying an inexpensive bluray player, likely Panasonic DMP-BD60 which appears to be an overachiever in terms of picture but (unavoidably) has a mediocre sound. I would integrate this in my purely 2ch system that contains the AMR CD77. Now, the CD77 has digital IN but quite unusually only USB. I could of course buy a DAC such as a used MF V-DAC to upgrade the bluray, but before I spend half the price of the bluray on that, I'm exploring possibilities to go through the DAC in the CD77 after all.

Hi Karel,

Unfortunately, the short answer appears to be "no." You'll find a couple of good explanations in this thread:

My most profound apologies. I managed to get that the other way round.

They exist in the pro audio world, but they are not necessarily audiophile quality. Try the Edirol brand (made by Roland). They used to have a really cheap cable product called the Edirol UA1D, with a little D/D converter which did SPDIF I/O for both Toslink and coax, and plugged into your USB port at the other end (I think it was OK in all directions - like a universal digital adapter of sorts but it was meant to plug SPDIF output things into your PC. They probably make a new version now but most of recent audio interface tools tend to have toslink-in, not coax. The UA1D can probably be found used. Otherwise, if you really want to have coax-in USB-out, you might try one of the $200-300 range converters (which tend to have more bells and whistles), or you could go real low-tech and do a SPDIF coax --> MIDI converter, and then add a MIDI-->USB converter cable to the back end... not pretty but...

The USB input is 16/48 only which defeats the purpose of feeding it hi-res formats.

The UA-1D appears to be discontinued, but there's a UA-1D on ebay with a Buy-It-Now at $50 and topdjgear.com appears to have them NOS for $90.
Disclosure: never tried one and I'm not the seller.
