If I plug my DAC in RCA on my A90d =>low volume + lot of distortion
If I plug my DAC in XLR on my A90d => windows volume at 100%, DAC @0db (2db is max), gain in high, volume at 90 is ok on my Stealth. But even at +2 at 99 (all max) it's not super loud... sometimes it's even say it's barely an average volume.
I tried a sonometre app of my phone put on the speaker : strangely the stealth outputs more db than my bluetooth B&W PX7.... but I would swear at ear the B&W (60db) was at least 2 times louder... impossible to keep the headphone on whereas the Stealth felt at a moderate volume (62db).
I don't get it.
