My take on it was that you guys did something that was of value to the audio community, and that it must have been as fun as it was informative. Additionally, I didn’t find the minor criticisms of methodology and cabling to temper the credibility of your work, especially considering the constraints of time and format.
I actually ended up buying the Black Ice Glass FX DAC and thought it sounded great. Curious what your personal thoughts on that DAC are.
Incidentally, I’m currently using an SMSL M400, which I found to be a cooler sound and slightly more detailed, but loses out to the Glass FX in terms of imaging/spatial cues. In my warm-ish system this was a trade off I was willing to make. Balanced outputs and MQA decoding also sweetened the deal. Still have the FX DAC, I’m having a hard time convincing myself to sell it.
Anyhow, I was going to advise the OP to avail himself of your invitation, but it sounds like he’s got it all figured out. Don’t mind hijacking this thread; he’s obviously no longer using it.
