24 bit 96khz. whats the deal?


do you only get the full benifit of 24/96 with 24/96 recorded discs. will it make any difference with normal CD's and DVD's.

Upsampling is what really makes the difference. If you ever look at test bench measurements, the best quality dual differential 20 bit DACS still have a definite performance advantage over affordable non-upsampling 24/96 DACs like the standard MSB link (when playing CD's). BUT WITH UPSAMPLING, THE ADVANTAGE GOES DEFINITELY TOWARDS THE UPSAMPLING CONVERTER/DAC COMBO, whether it's relatively cheap or not. MAKE NO MISTAKE, the dCS combos still beat everything else by a landslide! And as for affordable upsampling, the Bel Canto DAC-1 soundly beats the MSB Link with upsampling option...for now anyway.
By "full capability", it just means it has an internal 24/96 DAC that can play 24/96 audio DVD's. WHAT'S MORE IMPROTANT IS: CAN IT OUTPUT 24/96 THRU THE COAXIAL (or Toslink) DIGITAL OUTPUT? If so, you can get a better external DAC later, and use the DVD player as the transport.
It's a line level analog signal when sent to your amp (unless it's a digital amp, or has the DAC built in like the Wadia PowerDAC). A CD has nothing to do with 24/96, unless there is upsampling before the DAC (many feel that a 24/96 DAC in general is best for playing non-upsampled CD's, BUT THEY ARE ACTUALLY NO BETTER THAN A DUAL DIFFERENTIAL 20 BIT DAC DESIGN). DAC stands for Digital to Analog Converter. When we refer to a DVD player or transport outputting 24/96, we are speaking of a digital signal through a digital ouptut connector like toslink optical, or RCA 75 ohm coaxial. Both of those are called "S/PDIF", for Sony/Philips Digital Interface. A balanced 110 ohm line level digital connection is called AES/EBU, for Audio Engineering Society/European Broadcast Union. It uses a 3 pin XLR connection. It usually has less induced word clock jitter than the S/PDIF. The best connection is called I2S plus, but few manufacturers use it. There's also AT&T glass fiber optical, which has similar performance to AES/EBU. You might want to peruse "The Complete Guide to Highend Audio" sometime.
