James from your posts in the other thread.  This should answer many questions.

"New BDA-2 (BDA-1 stays in the line)


$2395 List USA

james"

"The Chip set in the BDA2 is capable of DSD but the software is not done yet.

james"


"Hi Ron,

No CD transport planned at this point.  We are looking at adding a CD optical drive to be used with our BDP-2 Digital player.

james"

"Hi Bob,

The new AKM chips preform at about the same level but 32 bits seems to be the new direction so we feel it is the better option going forward.

The prices are close ($200) but my intention is to leave the BDA-1 in the line because unless you want to use your laptop computer into the BDA (because the new USB has asynchronous 192/24 capability) there is no need to spend the extra money.  Also if you are using the BDA-1 with our BDP digital player there is no need for the BDA 2.

As well we will be releasing a USB Interface for BDA-1 owners which will allow them to use the new USB 192/24 feature with their BDA-1.

MEMO: To all Bryston Customers
SUBJECT: New BDA-2 DAC and BDP-2 Digital Player


October 2012


It is always difficult when you introduce a new product as someone has just purchased the current version of said product.

The BDP-2 Digital Player was designed for those customers that felt the BDP -1 did not have enough features - more drives , larger library capability, esata internal harddrive capability, increase speed with load times etc,  Lack of these features was what prevented some customers from considering the BDP-1 in their systems.

Remember the BDP-2 is not replacing the BDP-1 it is an additional product choice.

The "purist" can stay with the BDP-1 and those requiring additional features can go to the BDP-2. Also the BDP-2 is 1/3 more money than the BDP-1.

As for the BDA-2 external DAC the main reason for the BDA-2 was to add Asynchronous USB 192/24 capability.  DSD capability is also possible with the AKM chips so we are looking at that going forward (software). 

We will also be offering a USB Interface as well for those folks that currently own a BDA-1 which can be used with the BDA-1 and allow for 192/24 USB capability. 

Hope this helps.

Hi James,

What exactly do you mean with this? Bypass Loop Output...?
Wouldn't be an optional double balanced output, to go into the BP26 and the BHA1?
Which would be kind of wonderful.

Marius


Digital inputs.
• SPDIF COAX Bypass Loop Output

Could be wrong but believe it means that if you use the DAC with a HT Receiver and a DVD Player, for example, you can put the output of the DVD Player into the DAC and loop it out for the HT Receiver to decode

Great,

including native hardware DSD support! http://www.akm.com/datasheets/ak4399_f03e.pdf

Didn't you state you would have to rely on software DSD decoding James? If so, why not use the Hardware decoding options of this chip?

I would say give it 60-90 days as the orders are piling up already.

James,

Is the design already definitive? Otherwise I would beg you to have a second balanced and rca out, to feed both the BDA and the BHA simultaneoulsy with the same and undivided output, thus preventing the hassle with cable splitters and diminished sound quality because of that.
