In my deal, the BC DAC3 restructured the sound stage, to a more intuitive one, established far better bass impact, added that higher resolution you mentioned, and gained me more venue ambience and more 'you're there & they're here' events.
No question it's a highly resolving piece, but bright was not my take and I'm quite sensitive to that and reject it outright.
The BNC SPDIF, & AES inputs exceed the optical input by a pretty good ways.
Even when I play the D3 with the HT rig, there's no hint of brightness, etching, glare, etc. Merely not enough texture & immediacy as the (I suspect) lower echelon build of the Onkyo receiver. Those notes account for use with several amps too.
the mix is the deal... as always.
THX for the notes on the Berkley DAC.
I'm thinking of it yet probably will mod/upgrade the BC D3 instead, given the Berkely's price tag.
