48K, 96K or 192K


Please excuse my ignorance on the subject...

I just bought an upconverting DVD player which will also play dvd-a discs. There is an option to set the SPDIF to either "Raw" or "PCM" (default is raw). The output frequency of the LPCM audio data can be set to 48K, 96K or 192K.

The front two channels of this device will be fed into a digital amplifier feeding a pair of NHT Xds. The remaining channels go into a B&K AVR305 av receiver.

What does all of this mean, and how should I set this puppy up?

Thanks in advance.

First, I do not think you can feed the front L/R directly to the xDs amp since you would not have a volume control for those channels.

Second, if you are using only the analog outs, the settings for S/PDIF (the digital output) are irrelevant.

Third, the best arrangement is to set the S/PDIF output to RAW (that will permit transmission of DD and DTS in addition to PCM output) and connect the digital output to the B&K digital input. Then, connect the front L/R preamp outputs of the B&K to the xDs.

Fourth, an alternative may be possible which is to connect the 6 analog outputs of the player to the B&K.

Jim, DVD-A is 48khz/24-bit, so I would say set your player to 48khz. 96khz and 192khz are upsampled options for experimentation, but 48khz is the straight-through setting.

BTW, DVD-A is stunning IMO. It has phenomenal resolution and maintains the drive of redbook that SACD lacks. Donald Fagen's "Nightfly" re-mastered and released on DVD-A is excellent.
DVD is up to 24/48. DVD-A can be anything up to 24/192, at least in 2 channels, and up to 24/96 in 5.1. So, set the output for 192kHz in order not to down-sample and mangle the best discs.

Perhaps the setting needs to be made on a disc-to-disc basis? My Donald Fagen disc specifically mentions 48khz/24bit. I don't own any other DVD-A discs to compare.

I personally prefer to not upsample.
Tvad...Right on about DVDA! For years I have argued that it is as good or better than SACD, but for some reason most of those audiophiles who will accept high resolution have been snowed by Sony propaganda about DSD.

All my DVDA are 96KHz, although the protocol does allow for 192KHz.
