To play SPDIF in asynchronous mode, I'm considering using a switch on the 3.3v input to VDD_XO Trident. This adds about 6" of wire. Would it be advisable to add a bit of capacitance at the Trident input? If so, how much? TIA!

What do you use for source? The XMOS chips support SPDIF input and can feed the Buffalo MCLK for synchronous operation.

Thanks for the tip. I was thinking of direct toslink to B3Pro, but perhaps another option is available.

The default firmware could be altered to allow for that - then you could have 2 SPDIF sources (one consumer level coax, and one TTL/CMOS) without needing any external switching. If anyone is interested I can create a branch that does that.

Hi,

I would like this firmware branch to use two spdif inputs.
Where to find it?

Is anybody else getting frequency response changes due to OSF enabled at all?

Never heard of this... The OSF is enabled by default (register 37) and the default filter type is 'fast roll-off, minimum phase' (register 7). How are you controlling the DAC?

Hello
I have seen that the B3se Combo Kit now includes the PSU Centaur and no longer Placid-HD.
This is due to higher current needed by the ES9038 board, true ?
Without using 384fs a Pacid-HD would be sufficient ?
Centaur is not that low-noise - is there any noticeable effect in sound quality ?

Yes, the Centaur is for providing higher current, and ease of setup.

All critical sections of the Buffalo are powered by Tridents (or the reg of your choice), which dominate noise performance. They are very low noise, making the pre-regulator noise less of an issue.

While the M350 is not considered "low noise" by today's standards, it is also not "noisy" by any means.
