Sure...

I have downloaded a few DSD files in .dff format. Is it possible to feed these to my Buffalo II? Thanks.

If you can find an interface which will get the dff files out of computer and to the B-II. I do not know of any currently, but I do know there at least a couple of chips out there which support DSD output from a USB input. It would be very cool if TPA someday made a USB interface which supported DSD.
 
Yeah...

Duffy, that is a little different. The Foobar DSD thingie just converts DSD to PCM on the fly. Pure Music can do this as well (although this is a new feature which is presently a little buggy).
It would be much nicer to be able to take advantage of the B-II (and B-III)'s ability to play DSD natively, rather than having software convert it to PCM.
 
Duffy...

Understood. One would probably get better sound by using a sample rate converter program to convert dff files to PCM not during playback. Converting the files on the fly, during playback, is likely to use a relatively simple (and not necessarily good sounding) SRC code, and the extra processor overhead may also effect computer playback sonic performance.

Hello Russ or Brian,

Can your new S-PDIF and Sidecar accessory switching modules be adapted to B2? I am particularly interested in switching between I2S and S-PDIF inputs into my existing dual-mono B2.

Have the same question, but with other DACs.

I have the same question with BII, I want to connect the laptop Sony Vaio & a CD transport so I need switchable between I2S & S/PDIF input into my existing BII DAC.

The B-III's S/PDIF input module does not perform any switching... at all. It simply converts up to 4-channels of consumer-level S/PDIF (or AES/EBU) to TTL level. All source selection is done on the B-III. We include the switch with the module because it makes sense, knowing the user will be switching between multiple S/PDIF sources.

The Sidecar is basically a new version of the OTTO, but designed to mate up with the B-III's input header. You could certainly use it for other DACs, such as the B-II. You would just need to wire the appropriate pins in the headers.

If I understood well I need the two accesories: S/PDIF input module (to switch) & Sidecar (to switch S/PDIF inputs & PCM (I2S) or DSD inputs.

I have to connect first the S/PDIF input & after the Sidecar & after the BII, that's correct?

As I read I need 5VDC reg for Sidecar, but I don't know if needs other power supply for the S/PDIF input module?
 
So without employing the new S/PDIF card, can Sidecar accept and switch between one S/PDIF input and one I2S input, while outputing these two sources into B2? This gets complicated conceptually, as with dual mono B2 the S/PDIF input goes into S/PDIF and GND pins of first B2, then daisies over to second B2 from D1 to D1 and GND to GND. I'm thinking that to map I2S into first B2, one would need to go from Sidecar I2S output to first B2 GND(common to SPDIF), DSK (bitclock), D1 (wordclock), and D2 (data). So D1 would be used two ways: (1) for daisying S/PDIF between the dual mono B2 modules, and (2) for I2S.

IF this works, then in addition to Sidecar, to switch over from S/PDIF to I2S you would need to turn the S/PDIF switch off on first B2. (In dual mono the second B2 S/PDIF dip switch is always set to off.)

Am I confused?

Will not work with BII because you need to enable the comparator (to boost the signal to ttl level) with SPDIF and disable the comparator with I2S (to avoid mixing the signals coming out of the comparator -if there is no signal in the comparator, it will output low).

For dual mono, once the signal is in TTL level then you just share the signal with the other DAC
