Hi Rez digital to Benchmark DAC?

I've used my Benchmark with a variety of transports, cheap DVD based, CD based, PC, PC toslink output, etc.

I think the problem will not be can it handle 24/196, but where to find a player that will OUTPUT 24/196. Is there any music available at that resolution? I think HD tracks dot com does 24/96. Either way, the DAC1 will resample ANY input to 100KHz if I remember correctly.

I'm feeding a Squeezebox 2 to my Benchmark DAC-1. With the latest firmware, the Classic Squeezebox and Duet models will handle 24/192 and 24/96 files by downsampling to 24/48, which, via the Benchmark, still sound significantly better than Redbook CD. Only the Slimdevices/Logitech Transporter, some Linn DS players, and ?? others, can natively handle 24/96 or 24/192 streams. I'm not sure which of those include digital outputs, but at their price points, it's would probably be moot to then feed those streams to a Benchmark, or another outboard DAC.

Interesting...
Better than redbook via what kind of playback? I still prefer the Ayre cx7e's redbook to wav files via the benchmark but I would love to assemble a computer based front end that would outclass it.

If you want to fed a 24/192 signal to your DAC, no transport I am aware of will do that. You have to use a server based system, with a really good audio card that offers digital out. see the lynx studio TWO card (google).
24/176.4 and 24/192 do sound noitceably better than 24/96, and way, way better than standard RBCD.

The SPDIF spec (RCA coax cable) was never intended to handle the ultra high res bit rates and sampling rates. You need AES/EBU double wire double speed for that (digital XLR cable).
