Here's my claim: most people who have an SACD or DVD-A player connected to their receiver or pre/pro using the typical 6 channel analog inputs are losing resolution. That is, unless they have the right Lexicon or equivalent cost pre/pro.
It's my supposition that most receivers and separate pre/pros do their volume control in the digital domain; there is necessarily a conversion from A-D, volume attenuation, and then back from D-A. This is true even with all the tone controls and BM bypassed. There never seems to be any info published by the hardware manufacturers addressing resolution of such volume controls. For all we know, many volume control systems might be CD quality PCM, or at best, 96KHz. Conversely, if the attenuation is done in the analog domain, how do they maintain good transparency? Hell, a high quality 6 channel mechanical stepped attenuator part will run many hundreds of dollars.
I've read many posts in these forums, and it's clear that people strive to solve their BM issues using analog systems. The Outlaw 950 has analog BM for the 6ch inputs, and the ICBM is a very popular BM solution. Nobody wants to compromise their sound by converting the data to digital for BM, and the back to analog.
Why aren't we all as freaked about volume controls?
If the content has to be converted to digital for the volume control, why not do BM while its here? The loss has already occurred. Why don't manufacturers make the best of it? Maybe I'm missing something.
Comments? Contraditions?
Cheers!
