Vouk, you know it is rather surprising that on my listening tests, I find NeroAACEnc marginally better than both Apple's CoreAudio aka QAAC and FDK on low bitrates such as HE-AACv2 with PS at 32kb, though the internet is full with QAAC better than FDK better than Nero reports.
Although my listening tests are done on a reference AKG-K702, but I easily hear that annoying 'warbling' effect in QAAC where as Nero just drops the sonics a little in favour of overall sound stability, in my ears opinion of course.
What are your thoughts and experiences on this?
