I'm going to a single ended setup and thus don't need this awesome balanced DAC. It's a fully balanced (i.e., dual mono) Opus DAC. It has all the input modules - USB, Toslink, SPDIF as well as the Ballsie. It has the Metronome ASRC Module and the OTTO 2:1 I2S Switch module. In a word, it's loaded.
It has both balanced and SE outputs. The case is 13x11.5x2 (approximate, in inches). The power switch is on the left and the selector switch is on the right, positions for the selector switch are: Optical (left), Coax (middle), and USB (right). I doubt you will ever blow the fuse that is currently installed but if you do you should use a 3 amp replacement fuse. The front plate hasn't been engraved, so you can add whatever you want to.
The translation for the switch settings in the metronome manual are
"+" = 1 or high
"O" = open
"-" = 0 or low
The + side is the only side that is labeled on the circuit board, the "middle" position is disabled so unless you wire in another switch you should prolly never use that position. The metronome is currently set to 192 khz.
This Opus was built in May 2008 by a friend, who is a semi-professional builder. It is very well built and very clean (see pics). The DAC chip is the older WM8740 (i think...). Sounds fantastic...it was mostly used via the USB module out of an iMac and fed a GS-X. The GS-X has since been sold...and I've slowly sold my balanced gear.
This is a great fully balanced DAC. Asking $550 shipped in the USA, which is less than what the parts alone cost. Will split shipping for international...PM me for shipping quotes. Paypal fine. Please feel free to PM with any questions. Thanks...
