'outboard' high end dac's


Can anyone recommend an 'outboard' dac to be used in conjunction with an Oppo 105d (sabre 9018 chip), which might improve on the somewhat thin sound of the Oppo, improve on the (decreased relative to the Oppo) clarity noted when a Denon 1713ud (BB chip) was A/B'd with the Oppo, and decodes DSD and PCM formats?
Thanks

Not sure what the above gent means.....I have a Bryston BDA-3 and you can send DSD via SACD or files via the Oppo 105
Ben,
You are correct, via HDMI, as discussed in this month's Stereophile
review of the BDA-3.
