I have a Yamaha RX-V1300 Receiver that says it has 192kHz/24-bit DACs. If I use a cd player as a transport and use the receivers DAC, is this equal to Upsampling? I was thinking of buying an upsampling cd player, but would I be wasting money on something that I already have? Thanks

The simple answer is no. 24/192khz dac are mainly used for DVD-A, redbook CD going through this DAC will still be 16/44.1khz, unless your player has a unsampling feature(pretty rare)

Hmm...while we're on this topic, this brings up a question I've had for awhile...I've heard different opinions as to the real world benefits of upsampling...are there real world benefits/detriments to upsampling?

Not that i've heard. It wouldnt sway me one way or another. Had it,tried it and never tried it again.

The only benefits to upsampling would be to move the anti aliasing filter from 22.050hz, up to a higher frequency, and out of the way of any high frequencies within the music. The sound is smoother, but not what you would get if you just recorded with a higher sample rate.

I have also heard that some upsampling algorythms actually introduce distortion doing the mathematical upsampling calculations. Aside from pushing the anti aliasing filters out of the way of the music, I see no real benefit from the practice.
