My mac mini (mid 2010) is connected to an XDA-1 via USB (I am using Amarra HiFi coupled to iTunes). My hi rez files are downconverted to 44.1 kHz/16 bit, and I am unable to obtain any higher resolution. Looking to send higher rez files to the XDA-1.
Can someone give me a clue as to what I am missing? Do I need to upgrade hardware?
Many thanks,
Dave

The XDA-1 only does upto a maximum of 48khz via USB. So 44.1 would be the accurate figure.
If you want to go higher, the xda-1 does hi res on all the other inputs. So you would need a USB to SPDIF (RCA or coax) converter that is capable of
1. 24/192 khz.
2. Mac compatible.
Having said that....I noticed you have an XSP-1. The DC-1 is a FANTASTIC upgrade to the XDA-1 f you were wondering.

Thanks folks, I really appreciate your help. So my version of the Mac Mini at the optical out is limited to 24/96kHz (I think) which the XDA-1 should handle, and the XDA-1 USB is limited at 16/48kHz. While the DC-1 may solve both of those limits, is another (less expensive) option to go with an XDA-2 or an XDA-2 Gen2?
So the max rez I can do with this hardware is 24/96kHz via SPDIF between the Mac and the XDA-1. If I want more rez, I need to go to either an XDA-2 or DC-1. Do I have that right?
Again, many thanks.

Not really. With what you currently have your limited to 24/96 with your MAC TOSLINK optical out. But get yourself a USB to SPDIF adapter (RCA) you can get 192 khz. You just have to make sure the adapter really can do 192 khz, it's RCA(or coax), and it's mac comaptible. They aren't too expensive. Unfortunately the ones that are 192 khz are hard to find and some can be pricey.

Just curious, why DC-1 and not XDA-2 Gen2? Would I not get the same result over USB at less cost?

Everyone will receive different results as our ears and rooms are all different, I myself never noticed enough of an improvement using the DC-1 over my PT-7030, but that could be just my ears or my taste in sound, but the PT-7030 is that good IMO, ask anyone who owns one  , you could buy both and test it out yourself in your room and return or sell which ever one you don't want to keep, Emotiva offers the 30 day trial for a reason. Just my .02  Chad |

You never mentioned what the original resolution of your 'hi-rez' files is? Are they actually 192/24 or is this a theoretical exercise? I've never heard any difference above 96/24 so that's what I buy. As for the XDA-2 vs DC-1 there are a variety of opinions, I think they're both good, but you'll have to judge for yourself.

Fiddled with DVD-A for a while and SACD, tended to hear some differences with DVD-A.
I only have one 192/24 file on hand as a trial, just dipping my toe in the pool, tying to see if I hear a difference. Realize no need to go crazy with rez (also takes a lot more space to store), but have heard enough at shows like AXPONA to get me interested, they have had nice seminars to help understand the limitations of older recordings and provenance.
Perhaps I will switch back to optical and 96/24 for now, and give that another whirl with my XDA-1.
