I am unable to persuade the BDP-2 to play DSD128.

Has anyone had success with this?

It was tested with a PS Audio DAC and BDA-3

Yes, no problem (over USB) to Chord Hugo.

Does the BDP-2 support gigabit ethernet or just 10/100Mbit?

I just transferred about 10 CDs (ripped to FLAC via dbPoweramp) from my Windows desktop computer to the OCZ Vector-4 solid state internal drive on my BDP-2, and then transferred the same files to my server (which has a regular Western Digital "red" HDD). Both the BDP-2 and server and desktop are all connected via Cat-6 cable, Netgear gigabit switches and a Netgear R7000 router, all supporting gigabit speeds.

The transfer speed to the BDP-2 was about 17MB/sec (megabytes). The transfer of the same files to the server was about 80MB/sec.

At the end of the day, I don't transfer files to the BDP-2 very often, so it's not problematic. But I was wondering if there's anything I can do to speed up the data transfer speed?

According to the BDP-2 Owner's Manual it states that it does have Gigabit Ethernet.

"The BDP-1 and BDP-2 include Ethernet network interfaces capable of 100 megabits per second (100 mbps) and 1 gigabit per second (1000 mbps) respectively. Real world network conditions make it unlikely that these maximum speeds will ever be realized, but only 3 megabytes (24 megabits) per second are required for high resolution music playback."

Your 80MB/s transfer rate seems like a reasonable real world gigabit speed, not sure why your BDP-2 is only just over a fifth of that.

Must have something to do with the SSD and SATA interface.

Yeah, the SSDs in both my desktop and the BDA-2 are capable of the 80MB/sec transfer rate. The even an older SATA bus would support that too. My best guess is the SATA driver in the BDA-2 isn't optimized for that (since that data rate isn't necessary for playing music). If not, I was hoping that perhaps a different brand of drive might fix it.

MEMO: To All Bryston Customers
SUBJECT: Announcing Bryston Integrated Audio Device Card

May, 2015

Hi Folks,

We have been working on a Bryston proprietary “Integrated Audio Device” card with much improved specifications to replace the current two-piece ‘Soundcard’ and ‘SPDIF interface module’ (AES/BNC) utilized in our current BDP-2 Digital Player.

I am happy to report that an all new integrated version of the BDP-2 audio card is now going into production and should be available in a few weeks from now. All BDP-2’s currently on order will be fitted with the new Bryston integrated audio card.

Any current BDP-2 owners may have their units upgraded if desired.

That's interesting James. I'm an existing owner in the UK. What will the charge be for the upgrade and does it have to go back to a dealer or could you trust owners to fit?

A competent company like PMC could do the swap. I am still pricing the parts but I would say around $500 US.

So does this affect the BDP-2's price? I plan on ordering mine mid-June and the dealer wants a 50% deposit.

Rod_S · « **Reply #909 on:** 1 May 2015, 02:48 pm »

So what are the better specs?

We are going to leave the price the same for now.

Below the threshold of our AP. Will put something together once we have production versions.

Will the BDP-1 be upgradable or only the BDP-2.

Hi Haxter

Just the BDP-2.

What do you mean by "Below the threshold of our AP"?

We use very sophisticated analyzers and below threshold means it is below what the measuring gear can measure.

Here's an example of what I mean from a reviewer measuring the BUC-1 - http://www.hometheaterhifi.com/dacs/dacs-reviews/bryston-buc-1-usb-converter/page-4-on-the-bench.html

Hi James,

How does a new audio card handles sample rate switching? Currently BDP-2 with BDA-2 fades about 500ms of track when sample rate changes on AES/EBU output. I had a long email conversation with Chris on this issue and he told me that this is shortcoming of SPDIF protocol. Are there any improvements in new device?

Hi

I can't say I have had that problem - the new one seems instantaneous.
