I suppose the next thing to try would be 24/192 > iDevice > CCK > M8 > Balance Output @ line level > 4 pin XLR to dual 3 pin XLR cable > desktop rig balanced amp vs that same file played via iDevice > CCK > m8 > optical out > balanced desktop dac into same balanced desktop amp 0_o
The NFB-28 would be a good one to test as it is a balanced desktop amp/dac with analog inputs as well as digital so there would only be one piece of equipment and is priced around the same as a HiFi M8.
Since the M8 and iDevice is being used as transport in both scenarios, the signal path is the same and we can compare how the DAC and Amp sections perform against an equivalently priced,equivalently spec'd desktop setup.
Although, as far as I know, there isnt a way to feed an analog signal into the m8 from say the NFB-28 so it would actually be kind of difficult to compare the m8s amp with a DAC other than its own, so maybe we arent getting a full DAC test in this process. I think we would be getting a full amp test as m8 DAC could be used with both amp sections, however there may be synergys between the amp and DAC sections which would kind of make it crucial to be able to feed another DACs input into the m8s amp to get an accurate picture of things.
I realize we could feed it via optical on the LX version but that would relegate the feeding DAC into a mere transport since the m8s DAC would still be processing the digital signal unless Im missing something.
If anyone has got an idea of how to get another DAC's feed into the the m8 please share.
Also I believe if we did find a way to do this that to do the test properly we would need 2 HiFi m8s to do a fair comparison as the 2nd mate would have to serve as transport into the DAC feeding the first HiFi m8. Ugh...proper testing...
