New BitPerfect user here and just wanted to thank agentsim for making this wonderful app. It has definitely made a difference to my system.
I've been using 0.30 onwards on my hifi rig (Mac Mini 2011 Lion -> Weiss DAC202).
Since updating to 0.31, i've noticed a slightly worser sound, a bit of loss of definition and slam to bass notes particularly. I've A/Bed the two versions i have and can pick out it out everytime. Your release notes didn't really mention any significant changes so i'm not sure why it's happening.
I've made sure the settings are the same - no upsampling, no integer mode (my dac doesn't support it anyway). I've checked "use maximum device buffer size" which does improve the sound on my dac. When i check the device information (whilst playing) in each version, it is identical.
Any suggestions? The difference is small, but obviously i don't want newer versions having worse sound.
As for other problems, i have occasional stuttering at the beginning and end of playlists but it's not a big deal to me.
