Hi there! It’s me and my long-ass titles again.
I've had this question on my mind for a while, when I decided to use the Qudelix-5K not only as a BT dongle, but as a solution for all my needs (including desktop DAC) thanks to their DSP capabilities.
As some may know, the SINAD of the Qudelix-5K it's around 80-85 dB, nothing special but fine for their intended portable use, I suppose.
The problem comes when it's time to equalize and apply large negative pre-gain values to avoid clipping, just like in the case of the HD660S I bought a couple of days ago, I need exactly -14.5 dB of pre-gain to avoid clipping in the sub-bass region. Amir states in this post that a lower SINAD to begin with could be detrimental at an audible level after applying this type of aggressive EQ, to the point of being able to lose sound information within the 16-bit range.
I don't have any problem with the sound of the Qudelix, especially after equalizing, it's just a matter of peace of mind and knowing if I can improve my audio chain a bit, since I haven't had a DAC with SINAD higher than 100 dB for a long time to do a proper blind test and compare for myself.
Can someone elaborate more on this?
