BDP-2 Digital Player

Thats a complicated question as there are many issues to consider.

For example - in our DAC's the sample rate converter on the input is used with all PCM digital signals and it reduces jitter quite effectively. So you are faced with having DSD capability in your DAC but degrading PCM performance because you have to bypass the sample rate converter. Plus we have found that most DSD circuits upsample all the PCM digital signals coming in and do not play the file in its Native resolution.

Given that most digital music is PCM and will continue to be so you are almost faced with the dilemma of requiring two different types of circuit paths in one DAC or two separate DAC's that optimizes both PCM and DSD options independently.

Will one of the USB input be used as output?

Hi

USB connections are 2Way so any connection can be used.

Makes sense James

ah, you could always just design a small under $500 DSD only dac.

I currently have a USB stick connected to one of the front USB ports on my BDP-2 player and the main folder is called Music.

If I connect a second USB stick to the other front USB port of my BDP-2 player, can it be the same make/model and size as my existing USB stick and can the main folder also be called Music?

If not, how do I handle this?

If so, how do I differentiate one USB stick from the other in MPad (iPad Mini)?

Great to see you are improving all aspects of your products. This is excellent documentation that is easy to follow (and answered a few of my questions about the BDP-2's capabilities).

Nicely done!

Hi Guys,

Some customer within the last week have been having difficulties upgrading there firmware, I have written an article on an alternative method for upgrading the firmware and troubleshooting the issue.

Do you recommend this new firmware for BDP-1?

Yes it can be used on the BDP-1 as well.

James, regarding DSD,

it might be worth taking a look at the PS Audio DirectStream DAC. It converts all input data, either DSD or PCM, into 10x the rate of standard DSD. It then applies a filter in the output to convert the signal to analog. No IC DACs are used.

DSD is a matter of advertisement. It is important to have the feature but what good does it really bring apart from sheer compatibility with but a handful of music albums? Isn't it apparent that problems regarding DSD aren't associated just with the wide acceptance factor for masses? The problems are of a mechanical nature and this is the main reason why very few are using it. Editing DSD files is difficult to say the least. Workstations that can handle real-time editing apart from cut, move, delete etc. are few, not to mention those that can apply different effects. This is the reason why most DSD files are basically DSD-PCM-DSD files. Meaning the event was captured in DSD but was then transcoded to PCM for editing and was then again transcoded to DSD to be played in DSD-capable machines. Isn't that a bit nutty? Can we honestly say that this is better than pure PCM?

I am glad that Bryston is taking the time to think about it and not just „surfing the waves“. I can see that Berkeley design is doing the same thing. For those who want DSD, a PC application is supplied to convert DSD to PCM to be used with their Alpha DAC. But hey, if Bryston decides to make a DSD-only DAC, then it might be a welcome addition.

Cheers!

Hi Antun

I agree that this is an exercise in marketing and we are not going to rush into it.

We have looked at the PS Audio idea which is an option but just do not like the idea of up-sampling PCM or DSD as opposed to playing the Native file as is.
