I would have liked to test different filters, but just like the fixed/variable setting, you have to put/pull jumpers inside... Even better, pins are inaccessible to me, being below the USB board. Am I supposed to remove the latter first? Since this is not my unit, that isn't going to happen.
Not the first time that the manufacturer published great measurements that cannot be repeated by 3rd parties. Either he is measuring a prototype not representative of a production unit, or he cherry picked a good unit, or there is a lot of variation in production runs, or he is lying (hopefully not). Still all options are bad. The consumers should be able to get his numbers too with their units, not just an isolated good case in the factory.AG publish their own measurements with an AP-2722 and the 2nd and 3rd harmonics seem a lot lower.
Here:
It appears that temporarily removing the usb board is very easy - just two small external screws on the back panel. You don't have to put any tools inside the unit.
It is not coming from my rig, actually. All measurements are done with a battery-powered laptop on purpose. I've got other products pending for testing which don't have this issue whatsoever with either USB or Coax. And more importantly, that having both S/PDIF inputs performing the same, as they should.Something has to be going on with the grounding for the USB and coax to be that dirty in comparison to Toslink.
I first asked Audiophonics to loan me some DACs for reviews. It was one of them. They agreed. That's it.Was the unit asked for it did Audiophonics volunteer it?
I honestly don't care if it is easy or not. You agree that it is complete nonsense from a consumer point of view.It appears that temporarily removing the usb board is very easy - just two small external screws on the back panel. You don't have to put any tools inside the unit.
Because it's a DAC/pre/headamp for under €500.I first asked Audiophonics to loan me some DACs for reviews. It was one of them. They agreed. That's it.

Seriously, how is that could even be a thing? Having to open a piece of gear, then remove a board, in order to play with jumpers to set filters? When others have the possibility to do it with a single button on a remote?
Because the idea, to me at least, would be to determine if the "Issues" are clearly audible, OR, merely measurements that are mediocre and do not affect the final sound in any true way.Why spend money on gear with clear issues if you can just get something that doesn't have them?
@beagleman 'Most' people here on ASR do not care (or lower on their priority list) how an Unit sounds to one's ears in one's listening room as a link in one's audio chain. (If anyone takes offense thats own them) 'Most' Readers here are about Objective Measurements
There are tons of sites on the 'net where one can get Subjective Opinions on audio equipment
no, like does the actual sound output seem degraded when listened to or not.How does it sound.
You mean like clinical, analytical, warm, air - like more or less...?
