Hi James,

I found a link to the attached brochure of BDA-2:

http://www.audioaficionado.org/attachments/bryston-audio/20152d1349055019-bryston-introduces-bda-2-bdp-2-bryston_bda2.pdf

In the brochure it says:

The Bryston BDA-2 is a State-of-the-Art external Stereo D to A converter using fully discrete analog Class-A proprietary Bryston analog circuits, two independent analog and digital linear power supplies and dual AKM 32bit DAC’s.

The BDA-2 also utilizes a new asynchronous USB input capable of 192/24bit resolution.

Is this a 192/24bit or 192/32bit resolution DAC?

The new BDA-2 has Dual 32Bit AKM, does asynchronous USB 192/24 (or is this USB 192/32??) and pending software upgrade to enable DSD - are these the only differences? Also I read that it has 2db lower noise floor? I would assume both BDA-1 and BDA-2 has independent power supply and has transformer coupled SPDIF and AES EBU Digital inputs??

I have lots of question trying to figure out if its time to move on to BDA-2

  Wondering if the new version would comply as well as the BDA1 with the BCD1 being the chips don't match.

The AKM DAC chip is 192/32 bit.

The USB input is 192/24

Yes the SPDIF and AES Digital inputs are transformer coupled.

  So the bda1 is a better match with my cd1?

[golfugh]

The BCD-1 has nothing to do with it, if you send digital out to either the BDA-1 or 2 you are feeding the digital signal to the DAC of choice, the sonic signature will be based on the DAC chip and most importantly the analog stage of whichever DAC you choose.  The source is irrelevant.

[spinner]

  I thought that the timing was matched with the bda1. to the cd1

[golfugh]

Timing is in the feed from the BCD-1 to the DAC chip, ergo if you like the sonic signature of the BDA-2 due to the DAC and analog stage, you'll like the sonic signature of the BCD-1 through the BDA-2.

The AKM DAC chip is 192/32 bit.

The USB input is 192/24

Yes the SPDIF and AES Digital inputs are transformer coupled.

Is that true for BDA-1 too?

Thanks.

Thanks.

Hi - yes
