Bryston BDA-3

I think it depends on how much body you're looking for. Depending on what you're looking for when you say that, you may want to consider DACs other than the BDA-3. Although I think you will have to give up some cleanliness of sound and detail retrieval in exchange.

That being said, Dirac Live RCS might give you what you're looking for with your existing BDP-105D, or a new DAC like the BDA-3. I find it brings back some of the life-like quality to music that can be otherwise lost, without changing the overall sound signature of the rest of your gear.

Dirac offers a two week free trial period for their computer-based software. It's also available in a standalone box from miniDSP so you can use it with all your sources.

I'm located in San Jose, California. We carry Bryston and are a sales affiliate for Dirac so we can demo both of those. We also have some other DACs here that we do not sell but also highly recommend.

Nekoaudio, thanks again for your response.
I am considering the Luxman DA-06, the Bryston BDA-3, the Auralic, and am less enthusiastic about the Hegel  HD30 and the Wadia di322...of course this ranking could be far from the mark.  Considerations include compatibility with the Oppo 105D which thus far seems to do a phenomenal job with high resolution DSD files.  The OPPO will not output un-decoded SACD, which is not an issue since I possess very few such recordings.  As I mentioned it does wonderfully with hi res DSD files....possibly the audio is a bit thin....and less than optimally with CD's.  As I increasingly appreciate, the quality of the recording itself, CD or DSD, is all-important.  That said, the Oppo is wonderful but nonetheless perhaps the weak link in my otherwise high end system, so that improving on its audio output....CD's foremost, DSD's possibly, DVD audio (including blu-ray)....is worth some effort and expense.
Further thoughts and recommendations are of course appreciated.

Well, the BDA-3 is probably going to be the most functional of the bunch, considering you want to feed it DSD from your BDP-105D. I recommend you audition the Auralic Vega though, even if it won't be as functional as the BDA-3. Also, I personally find it a little harder to navigate through the Auralic UI instead of just having buttons for everything like on the BDA-3.

Thanks, Bill K.  Unfortunately neither reviewer comments on the HDMI input
