Which Receivers/Pre-Pros Boast End to End Analog?

    I posted a somewhat related question in the Audio/Video forum, but didn't really get anywhere with it. Thought this might be a more relevant forum.

    Which pre/pros/receivers and receivers offer full analog handling from analog inputs right through to pre-outs/speaker terminals? You see, it's my suspicion that nearly all but the most high end equipment have digitally implemented volume controls, and that even for the 6 channel direct inputs, most of us end up with an A-D/attenuation/D-A conversion for each channel.

    Thoughts?

    I'll start by pointing out that the Bryston SP1.7 boasts a full analog mode including volume control for stereo only - not 6 channel direct.

    Thanks!
    Martin.

    ^^ yes, but when you turn on Direct or Pure Direct it bypasses that.

    I don't know about volume control. Denon's direct modes are supposed to be all analog.

    Michael,

    Very good! That's exactly the kind of info I was looking for. Thanks!

    Incidently, I emailed the Outlaws, and within half an hour I received an answer - sounds like that (or something like it) is what they do.

    Now I can sleep easier at night... [​IMG]

    The next question which comes to mind is, how transparent is it? Most DIY types (the tubeheads, anyway) will attempt to keep at most one resistor in the signal path for attenuation. The ladder approach will mean that at some settings, multiple resistors will be used in serial (or parallel). Is this the sort of thing that does "justice" to SACD and DVD-A? Perhaps it's time to build a nice 6 channel tube preamp with a $400 ganged stepped attenuator... [​IMG]

    Martin.

    Digital potenitometers (digipots) process the signal in the analog domain. They differ from reqular potentiometers in that instead of steppped attenuators they use a microprocessor to choose the apropriate tap. Think of digpots as potentionmeters with a brain.

    I suspect the answer to the posters orignal question is 'NONE', or at least none that I know of.
