Ozzy,why not just sell the BDP-2 and buy a Bridge II ?
Sorry if it was mentioned above, but does it work if you connect via COAX?
The IAD board is why I did not upgrade from the BDP1 to the BDP2.
Somewhere I recall reading when the IAD update card came out, that the PSA DS did not harmonize with the output of the updated BDP2s.
Thank you for the help thus far.
Both the RCA and the XLR will not play 24-192hz files from the Bryston to the PS DS.
With the Bridge 2, wouldnât my 6TB Hard Dive still need to be connected to a computer for access? With the Bryston the Hard drive connects in the back. Then with an Bryston app I can select music anywhere in the house via laptop, I pad, etc.
The new Bryston IAD board probably is the culprit, but it still seems this should have been addressed and resolved by now.
Bryston claims the problem is with the PS DS they say it is out of standard spec.

Ozzy,
Just FYI, my BDP2 to DSSenior via Land Rover and Belden Gold outperforms any other connection/cable I have tried. Hope you solve your dilemma.

jedi1,
Have you ever tried running the Bryston direct to the PS DSS via the Digital @ 24-192hz?

Iâm going to go in the lab tomorrow morning and test a DSD. Iâve always been an exclusive USB, Bridge, and I2S user so I donât actually have first hand experience listening to 24/192 files through the DAC via COAX or balanced. Standby.
jamesh,
Thanks but, DSD seems to work fine. The problem is with PCM 24-192hz.
I hope you can still try that out.
ozzy
Sorry if I wasnât clear. I know DSD is working, Iâm going to test a DS DAC here to see if 24/192 is working right.
Ok, thank you! Does the Bryston have the new IAD board?

I had a BDP-2 (with new board) and a Directstream Dac. I had the same problem on 24/192 files.
I tried multiple BDP-2âs and multiple Directstream dacs and they all had the same problem. I also tested USB using WW Platinum 7 USB cable and while it played 24/192 it did not sound as good as using COAX (WW Gold 7 SPDIF cable). This was due to the BDP-2 USB output vs the SPDIF output, the BDP-2 USB just does not sound good to me. I have tested on a few different dacs plus the WW Platinum USB cable sounds great on other streamers so I think it is the BDP USB.
Eventually I replaced the BDP-2 with a different streamer after hearing others having the same issue. Problem fixed.
So I just tested it in the lab. 192/24, WAV/FLAC, COAX/Balanced⌠All work as expected. Sounded great. A few of the guys downstairs mentioned they remember this coming up a few years ago and they concluded it was something with the BDP and DSD not jiving. Iâm never one to blame another company, so I donât want to say itâs their fault. It might simply be an incompatibility between the Bryston and DSD.

kaarmstrong,
I was hoping that wasnât the final solution. Bryston blames PS Audio, PS Audio does not seem willing or capable to help.
jamesh,
I take it you did not try the PS dac with the Bryston BDP, that combo is the problem.

Weâre looking into it and I have asked Ted to chime in. Brystonâs saying itâs our DAC that is âslightly offâ which is strange since our DAC works with every other device I know of on the market - and it has a wide enough acceptance range that even if itâs a
bit off it shouldnât matter. In any case, I hope Ted can help understand.
The real problem here is that in the end, our customer is struggling and thatâs whatâs not right. We will do everything in our power to help - though, that said, if thereâs a problem from Bryston weâre not going to be able to redesign the DAC
to fix it.
I hope there is a simpler answer.
Finger pointing doesnât get the customerâs problem fixed which is all that matters.
Thanks Paul for your comments. For what its worth the Bryston has worked with all other dacs that I have tried.

When this first came up neither Bryston nor the customer that had the problem would let PS Audio borrow a device to test with. Nor would Bryston provide a scope shot of their output waveform or a description of what they changed that stopped the connection to the DS from working. We suggested some experiments that might make a difference or at least rule some things out. I never heard back and I donât know if PS Audio did either. Two of the people at PS Audio that were working on the problem are no longer there. If I had a device or perhaps if I had a good scope trace of the waveform I might be able to narrow it down.
For the next release of the DS software I intend to try to raise the frequency of the clock used to process inputs (for multiple reasons.) Thereâs a chance that if the incompatibility with Bryston is electrical that that might fix it.
Thanks, James. Iâve done the testing more than a few times and itâs only a problem with the BDp2.
Thanks Ted, and Paul and it is only with PCM higher than 24-96hz using the XLR/RCA digital output/input.
And⌠if you need a guinea pig, I guessâŚgulp I could send my Bryston to you Ted.
ozzy
I understand that itâs only 24/192. Because of that I always suspected that it wasnât a protocol problem so itâs always seemed that it had to be something that changed the waveform output (either level or timing) in the Bryston update. Iâm busy at the moment but Iâll have more time in a week or so. We could either ship some hardware around or see if the software change works first. Iâm guessing that after I start it would take anywhere from a few days then to a week to write and test the software change.
Ted,
Ok, just let me know when or how I can help.
