I see no eeprom on the new Buffalo 32 circuit board, only an empty socket? Just wondering, what is the reason.
Regards René.

Because its being controlled by a volumite. :)

Hi Russ,
I need a little clarification on volumite:
1. I always thought that digital control of volume within the DACis not as good external passive types. Has Buffalo32/ess9018 got any special features that makes it different?
2. Does the default (2 chnl stereo) configuration for the ess9018 allows it to run without an external micro. In other words can i run Buffalo32S without volumite or on board micro/firmware
Also:
1. what is the clock frequency of the crystek oscillator for Buffalo32S?
Thank you.
acko

1) This may be true for some DACs, but the Buffalo has a 32bit data path, and the attenuation has better performance both in terms of dynamic range and channel matching than you could achieve in an analog solution. That said if you prefer analog there is always Joshua Tree. I find both volume solutions very pleasant.
2) No, You will need a micro controller no matter what as some internal channel remapping must occur because of our allowing DSD input along with SPDIF and PCM. The Volumite is a controller. I simply put the necessary firmware in it. :)
1B) 80Mhz. This easily accommodates 192khz 24bit input via SPDIF.
Cheers!
Russ

Hi Russ,
Further question on external micro/firmware:
Since Buffalo32S control firmware lives on the external Volumite does that mean Volumite has to be ordered together with Buffalo32S. What if I want to use an eternal passive vol control only? Will you then provide the micro on the socket of the Buffalo32S board?
Please advise.
Regards,
acko

acko, I used volumite to fill the role of the on-board controller as well as control the volume. We will ship the board with an on-board controller. I found that it makes more sense when using Volumite to dispense with the on-board controller.

Thx, Lennert Well technically you probably could, but we found some things about the way the ES9018 resets that makes it safer for us to develop new firmware. So as Brian said, no I would not recommend using the old Buffalo firmware. Cheers! Russ

I was referring to using the Volumite to control the Buffalo setup as well as volume.
To be clear, though, the Volumite hardware has not changed at all, just the firmware.
