Can the BIIISE controller work with a BII for volume control? I have two use cases, first for a four channel setup and second for a dual mono setup? If I had a multichannel I2S source like the exadevices USB or eventual Twisted Pear USB board, would there be any complications using these two different version together for either use case? I am considering an upgrade or addition and am trying to figure out whether to keep the BII and add a BIISE or whether it would be better to use only the BIII products together.
 
I'm very interested, but I have some dumb questions :
SPDIF input, can I simply connect it to a BNC/RCA connector to be connected by coax to CD player ?
For SPDIF/I2S input switch, what type : momentary or non momentary ?
Can it accept I2S from CM6631 USB interface like this one :CM6631 24bit 192kHz USB to Coaxial and Optical Fiber Board New Version | eBay

I all the above are yes, so what I need :
Buffalo III board with trident regs
IVY / Legato or other balanced to unbalanced converter
regulated power supply to power Buffalo III board

Am I correct ?

In order:
- yes
- non-momentary: you need to pull the contact to ground for the other input to work
- likely, but do remember there are many variables in I2S signal configuration. Fi. in some cases you might need a microcontroller to change the alignment.
- You need to add a bi-polar PSU for the I/V stage.

Thanks Leon. I already have John Broskie's BCF. As Buffalo III SE can be configured as Vout, I don't need other analog output stage, right ? I just want to re-use what I already have.

How about this USB interface : http://www.ebay.com/itm/24bit-192kH...mplifier_Parts_Components&hash=item4d0644e5ae
(there's a spec of it's I2S output on the bottom of the page)

You would want to control them separately. The best way would be custom firmware.
 
Hi, I just ordered the Buffalo III SE with regs for use with Amenero usb to I2s converter. I don't have much experience with digital - build valve amps and horns. I am interested how best to interface the Buff III with a valve input stage. I modded a TDA1541 based Sony337 CDP by just wiring the (dual) chip up to a 20 Ohm resistor on the tube grid (d3a) for I/V (a la Lampizator) and like the results.

I understand the Buff III is selectable for either V or I out. AC coupling the V out would indicate a transformer perhaps? If so what kind of spec is needed?. If using I out, would a simple low R on the 1st tube stage do it OK? What is the standard way - is this an external function? Sorry if not up to speed. Grateful for any advice.

Hi Truetone. Check out the thread Buffalo and Transformers. There is a lot of good information in that thread that should answer all your questions.
 
I noticed you're accepting pre-orders, but there's no "add to cart" button beside the BIIISE kits. Is there another procedure for pre orders or did I just miss out?

I opened the pre-orders up for a limited number of units so I would not be completely overwhelmed. I will have plenty in stock, and they will be available in a few days.
 
For complete the buffalo dac IIISE with 2 s/pdif input . I will need the following modules ?:
-Buffalo-IIISE 2-Channel DAC $379 USD
-Legato v3.1 Kit for Buffalo-II $115.00 USD
-Placid HD Power Supply Kit $60.00 USD
-Placid HD Bipolar Power Supply Kit $90.00 USD
-15V+15V (30VA) Power Transformer $25.00 USD
-9V+9V (15VA) Power Transformer $23.00 USD

The S/PDIF transceiver module is required for buffalo III SE?.
