Hi.
The USB section of the Bryston manual is a little unclear, so I’m hoping someone can confirm some details for me.

I work from my music software on a 2015 Thunderbolt MacBook Pro. Generally, I will be in 24bit/48Khz.
A have an Apple Superdrive which I use to play CD’s, which I presume sits at 16bit/44.1Khz.

The Bryston manual only specifies 16bit for USB.
My question is - is that the limit of bit-rate for USB on the BDA?
Would I need to convert the USB to Spdif or optical to use a BDA in 24bit, or will it happily support 24bit through USB - automatically sensing and switching up when prompted?
I’m not bothered by the No upsampling on USB.

Clarification and advice on suitable DAC’s much appreciated.
I can’t really afford a BDA-3, otherwise I would use HDMI of course.
There are of course HDMI to Spdif converters, and this might be the best option for me?
I looked at the RME API-2fs, but I’d really like a Bryston BDA-2 if possible.
Many thanks.

  I don't know the answer to your question but when I select dvd quality from my computer settings I can hear more space between notes but it is subtle difference. I know Joe Satriani live in San Francisco is 24 bit but I'm not aware off hand of other recordings.
 I use the BDA-1, the BDA-2 from what a friend said is more laid back. Haven't heard a BDA-3 knowingly, the Dealer may have had a BDA-3, anyway someone said the the BDA-3 is comparable to the BCD-3 which I own and its the most refined sound I have heard and IMO bettered the Dealers more expensive Bryston system.

Interesting on my old computer I could adjust the sound level of the BDA-1, which by default was set at 80%. When adjusted lower it had a much different sound output.

From High Fidelity website:

Published: 2. March 2013, No. 106


Peterborough, Ontario, November 14th, 2012 – Bryston LTD (Bryston Limited: Music for a Generation), builders of the world’s finest audio electronics and celebrating 50 years in 2012, has announced the introduction of the BDA-2 outboard digital to analog converter (DAC).

Bold words, indeed. But then, they come from no less an authority than Canadian Bryston, one of the better-known audio brands both in the world of consumer as well as professional audio. Similarly to such British manufacturers as ATC, Harbeth, Tannoy, PMC, dCS, or Dynaudio from Denmark, Bryston Limited is a company equally at home on both sides of the “glass”. It is also one of the few successful manufacturers of electronics; almost all the others, apart from dCS, mainly offer speakers.
Recording studio provenance of audio equipment usually guarantees one thing, in addition to its user friendliness: high manufacturing quality and thus long equipment life. Satisfied owners of twenty years old or older Bryston amplifiers will be happy to confirm that. But what about Bryston DAC owners? Well – they have not yet had enough time to find it out as the BDA-2 predecessor, the BDA-1, was actually the first DAC offered by the manufacturer since 2010.
The new BDA-2 is not meant to be its direct replacement but rather a product line supplement. The immediate reason for its launch was the need to upgrade the USB interface, previously limited to 16-bit, 48 kHz signal. With the new model we get an advanced, modern solution based on an XMOS chip, offering asynchronous transmission of signal up to 24-bit, 192 kHz resolution. USB is the domain of computers and thus difficult to manage. The BDA-2 arrives with its own driver on a flash drive in the shape of a key. During the review, however, it did not yet support Windows 8 that I use. Usually, Windows based computers limit playback to signals to 24/96 without a dedicated driver. Here it is different – the input is completely inactive until we install an appropriate driver from Bryston. Thus, I had no means to test the DAC's USB interface.

Sorry, I meant to highlight the following sentence:

That’s great info Barry. Thanks so much.
I assume that drivers aren’t needed for MacBook operation, only for Windows.
Anyway, nice to know I can ignore the BDA-1, and wait for a BDA-2 bargain when it comes up.
Cheers.

Check out the following:

This fellow also has some great kit as well.  Plus, CAD$ is much in your favour.

Ciao

Thanks Barry.
I’m looking for a UK 230 volt model.
Sorry I didn’t make that clear.
USA trending price is $800, so I’m hoping to snag one here for £800 in the next few months.
Fingers crossed.
Cheers.

   My sound setup on my secondary computer used for headphones.
As I mentioned Joe Satriani San Francisco is 24 bit. Played back at 16 bit, sounds a bit distorted. Played back in 24 bit the sound just opens up. :drool:
