What is a reasonable cabinet size for a Buffalo II DAC consisting of the Buffalo II, IVY III, Placid + Placid BP P.S, Volumite, and two transformers? - I was thinking of something on the order of 12" w x 8" d x 3" h. (12" x 12" x 3" better? - or too large?).
Any benefits of compartmentalizing enclosure to separate transformers and power supplies from rest of circuitry?
What is a good source for small quantities of miniature shielded coax for use from SPDIF to Buffalo II?
OK to use unshielded twisted wire from IVYIII to balanced outputs?
What wire is best to use from IVYIII to SE (RCA) outputs?
Is there any benefit to using a filtered IEC connector in this application?
Many thanks,
Allen C. /

A larger cabinet would give you the benefit of larger distance between the transformers and the audio circuitry. If you use toroids that shouldn´t be an issue. Place the transformers in the front and the DAC in the back, and you should be OK. I personally dont think there is any benefit in compartmentalizing the cabinet. Just keep the wireing tidy. No crossing wires. Keep AC wires separated (shielded) from the rest. And as mentioned, transformers and DAC at opposite sides of the cabinet. If you have some SCART or VGA cables to spare you will find lots of thin coax inside those. Twisted wire should be OK to use on outputs, both balanced and SE. Could also use shielded wire but probably no issue. I use some shielded microphone wire. On my Buffalo 32S I had some problems with small dips on AC mains causing the DAC to loose lock. Adding a small simple filter (0,1 uF X1 capacitor and a 1M resistor) across the AC mains input fixed that. So a filtered IEC might be a good idea, or you can DIY the filter and save some money.

You are right. We Norwegians are very fortunate indeed. Far from any earthquake areas, no nuclear powerplants etc, etc...
Good luck on your build!
Stein
