I noticed a serious problem with MAYA U5, it also have other users. Maya from time to time for no reason generates a very loud noise, it can be hard to scare or damage hearing. The noise goes away when you change the sample rate or unlink card.
Most likely cause is underdeveloped drivers.
There is no good equalizer, it does not adjust low frequency 30-60Hz, 80-120Hz and higher> 8 kHz.
Addition, it is very sensitive to electrostatic discharge, sometimes you simply touch the wire and Maya off.
Maya-U5 is a good product (good sound), but needs updating.
