Just got my replacement in, thankfully a great unit with no imperfections!
Found my old Apple remote and I agree on the Apodizing filter being the best of the bunch; the IIR filter adds a little bit of treble bite which is not unpleasant actually - I wouldn't say that is a bad thing but I still like the roundness of the Apodizing filter.
Feeding into a Parasound D/AC-2000 and a/b-ing both doing my best to level match, I find that the Para has a smidgen more detail and larger presence to the sound. The Concero as a dac-only is by no means thin sounding but in comparison to the Parasound it falters a teeny bit here. It truly is vey close, not even a stone's throw away. The Concero has an amazing noise floor and has a noticeably blacker background than the Parasound, I found the same to be true with the Stello DA 100 signature not surprisingly. It must be whatever Resonessence did with their power section/filtration is amazing; bear in mind I'm using a freebie printer usb cable with no extra usb power cleaning devices like iUSB with a Macbook plugged into the AC adapter.
Now the bad: feeding into the old Parasound I also cannot seem to use the filters which is a small bummer, only stock setting will output sound. This is likely because the DAC handles at max 48khz. Maybe I can downsample somehow in software?
The remote also works seemingly sporadically, not sure what the deal is here. The Concero registers the button press but it doesn't skip songs or pause half the time when I am in Audirvana.
The Concero being a device that you can simply just listen to and enjoy even if it isn't the best seems to absolutely be my experience as well. Wins a "not crap" award from me ;)
Just a quick thing, i had issues with my Concero when i actually changed my Windows Audio settings to 24bit/192khz. The filters automatically upsample so you dont need to change the settings within Windows. Once i changed the Windows settings back to 16bit/44.1, i was able to set the filters again.
Could this be a similar issue your having with your Mac..??
Oh wait, yeah your parasound only supports upto 48khz..? Hmmm could definitely be the issue there.
