Direct Stream DAC decoding ('playing') DXD 352 Khz


#1

Am I wrong to ‘assume’ that the DSD will play DXD 352? DXD is PCM so it should right? I want to download this great recording this morning but I wasn’t sure if I needed to go with the PCM 192, or if it’s fine to go with the DXD 352. . .??

Thanks.

The DS does 352.8k PCM / DXD over USB and I2S (but not the bridge, S/PDIF, AES/EBU or TOSLink.)


#3

Thank you Ted. I always thought the Bridge / Bridge-II (was) an I2S interface??


#4

Yep, the bridge to FPGA interface is I2S which does support higher sample rates, but it’s the CPU on the bridge that’s the bottleneck.


#5

Ah. You learn something new every day!! Might that ‘bottleneck’ be the limiting factor that prevents the Bridge from supporting “double DSD?” I wonder if PSA has any plans to address this Bridge/CPU bottleneck. . .

Thanks again Ted. I appreciate all your feedback on the forum. Cheers.

We do, in a Bridge III but work on that has yet to even begin. Lots of planning and thinking but no actual work.


#7

Yike. I hope the people that pay me do not come to realize thinking and planning is not actual work.


#8

Elk, I think there are a lot of people that fall in that category!

Paul, will Bridge III still be a slide-in module like Bridge I & II? I know at one time you were thinking of a separate box.

I hope Biii has galvanic isolation and FPGA so it can be updated as new formats come out.
