Yup.

You can try adding 75R resistors from + to GND for both inputs.

Got mine yesterday (Saturday morning in Melbourne, Australia).
Working by evening.
Toslink uses 2nd power rail.
Rails set to +15.000, -15.000, +6.000 (Digital), +6.000 (Toslink).
Brilliant, so far. Wife comments: "Warm & detailed at the same time. Stunning."
Brian, is there a particularly optimal value for Digital voltage? Or is 6.0v good enough?

there is still room for a hires USB board and the AC1.

Cheers

How would you compare the two? Are there improvements?

Congratulations!

I want to be careful with comparisons since I send 48V phantom power through my Buffalo/IVY combination. While the friendly folks at Twisted Pair helped me out with refitting the IVY for free something was giving me pretty high distortion levels after this unlucky accident.

Subjectively I would say it sounds a littler brighter but with even more clarity if that is at all possible.

I have been switching forth and back betwen my Lavry DA10 and the Buffalo32 and I have to say I like the Buffalo better. That is of course completely subjective. I hope I will get some measurements done next week to also get a comparison on that front.

Cheers

Thomas

5V is the recommended value for VD on the 32S.

I recall reading a post by Russ about it at the TP support forum.
