One can always program a Harmony remote.  They have the BDA-1 and BDA-2 in their database as well.

Phil I would think that should work unless there is something different about the codes from the BDA 1 & 2 vs the BDA-3, I wouldn't think so.

Remember that one must specify the input on the DAC and the BDA-3 has 4 HDMI inputs

I used a Harmony One when I had both the BCD-1 and BDA-1

The BDP-2 with the new IAD sound card outputs single rate DSD (DoP) over the AES and SPDIF outputs. Does the BDA-3 accept DoP via its AES and SPDIF inputs? I assume this is covered in the manual, but Bryston has not posted the BDA-3 manual on their website yet.

Hi

I have not tried that yet - just USB at this point.

Well, I hope you won't keep us in suspense too long.

Tried it with the BDP-2 and No the BDA 3 only decodes DSD on the USB input.  I was told this is the only way to do it legally?  I will try JRiver and Audiorvana as well.

Thanks James.

That's a shame because my DSD files sound better over the AES connection, SPDIF is second best, then USB. They are all close in sound quality though. The difference between AES (best), SPDIF (2nd) and USB (3rd) is much more pronounced when playing 44.1K FLAC files.

I was told this is the only way to do it legally?  I will try JRiver and Audiorvana as well.

I wouldn't think there would be any legal issues since dCS's Debussy DAC will decode DSD over PCM (DoP) through its AES and SPDIF inputs. DCS invented the DoP standard in 2011.

There are several DACs that can do DoP via SPDIF - there's a database here - https://docs.google.com/spreadsheet/ccc?key=0AgVhKcl_3lHfdFVyenBBNjNpQ2lieG81WGpqQTNfVUE#gid=0

The first of the BDA-3 DAC’s getting ready to leave the building !!!

+1 I Prefer Spdif over USB too.  No problems playing DoP via SPDif from my BDP2 to my Hugo and Esoteric DACs.
Seems odd to omit this  feature from the BDA3

Hi

In order to play DSD over SPDIF you would have to bypass the Sample Rate converter in the PCM circuit (which reduces jitter).  That's why our new BDA-3 DAC has a separte circuit path for DSD and PCM files.

Here is something I wrote a while ago which may help.

Hi folks

I have been asked a number of times by our customers our position on DSD so please find below our thoughts. DSD currently is available in a number of variations. Assuming you want to produce a product that can grow with time and market forces both hardware and software should to be considered.

DOP 64, 128, 256, 512 (last 2 are theoretical at this point) and DSD Native are the current options. Currently DSD is possible relatively easily with current software and hardware utilizing DOP 64 on current DAC’s and to some degree DOP 128

For example:
DOP-64 requires 176.4 capable DAC’s
DOP-128 requires 352.8 capable DAC’s
DSD Native 64 x 44.1 (standard 2.8224 MHz) (which is equivalent to 16 BIT 176.4 PCM) DAC’s.

Currently the majority of DSD capable products today are using DOP-64 architecture and some DOP-128 and DSD Native. There are also some manufacturers that have proprietary hardware and software which are capable of DOP-64, DOP-128 and Native DSD but proprietary software is not compatible with USB 2 drivers etc.

The other issue we are investigating has to do with the sample rate converters in DAC’s.  In order to activate DSD the sample rate converter on the DAC inut stage would have to be a custom piece because current sample rate converters are not equipped to handle DSD to the best of our knowledge?

So that means in a standard PCM converter like our BDA-2 you would have to bypass the sample rate converter which may cause more jitter because our current sample converters reduce jitter on the input.  So in Bryston’s case we definitely want the sample rate converter in the circuit for 44.1 to 192 PCM signals. Also some DAC’s we have looked at that are DSD capable convert all the incoming sample rates (44,48,88,96,176,192Hz) to a very high single sample rate ‘Asynchronously’ whereas our preference with our DAC’s is to maintain the ‘Native’ incoming sample rate throughout the conversion process with all PCM signals.  If we do up-sample we do it in a synchronous manner so (44.1 becomes 176.4 and 48 becomes 192) not asynchronous.

So before Bryston goes down the DSD road I want to make sure we are providing our customers with the full story and allowing for possible advancements in both hardware and software development as much as possible. Also please offer any info or input if you feel we are mistaken or misinformed.

Note- DOP – Stands for DSD over PCM

I believe there may be sample rate converters (for DSD) but they may be costly  - e.g. - http://vintageking.com/weiss-saracon-dsd

Hey Phil,


What about the Audirvana Plus Izotope converter? http://audirvana.com
has all the options:


  

seems best in class.... http://src.infinitewave.ca

(even has a promising remote app https://itunes.apple.com/app/a+-remote/id1008281758)

cheers,
Marius

Thanks for the info - I'm sure there are others.  I just play files in whatever format they are.  As consumers, we don't have a choice on what music is either recorded to or released in a particular format.
