The following is an update to my 901 review, it has been placed on the original post for this thread and in the amp review section.
Here are some updates as of 6-24-02:
The switches on the 901 are not absolutely silent all the time, I sometimes hear a very slight transient when engaging or disengaging the digital/analog, high/low switch, or operating the volume control, still quite acceptable.
So far I can get the 901 to sync at 96kHz with DAD discs (DVD-V) only (thanks to Dusty Chalk for the DAD's info!). I have a Bucky Pizzarelli DVD-A put out by Chesky that on the DVD menu you can select 2 channel 24 bit/96kHz output, the DV47-A displays DVD-A V, but it still only outputs 48kHz to the digital out. In my 901 review I stated that the 901 DAC sounded better to me in all cases, I am now finding that on DVD-A discs I like the DV47A DAC better. Somehow I think the DV47A is artificially crippling the digital out down to 48kHz on DVD-A discs but the internal DAC is operating at 96kHz.
Based on some interconnect education I received at this very site I have changed my digital connection between the DV47A and the 901 from TOS LINK (optical) to Coax.
