Here are my thoughts on group 2. Sorry for the delay. I'm currently abroad, luckily I managed to listen in the studio just before I left. Hope I didn't miss anybody.
In general: I think the biggest problem by far was the extremely harsh hi-hat that made it almost impossible to listen to the original loud. I confirmed this by checking on multiple home systems and asking several jane and john doe's that have no expertise in the audio field. Nearly everybody commented on the harsh highs. Some couldn't say what exactly was the cause but most said the highs were nearly unbearable at louder listening levels. Which makes it so surprising that very few actually addressed the problem. Some of you even boosted the highs! So, with this in mind, here are my comments:
Slip (my own master): I went perhaps a bit overboard with the hi-hat taming. Using a complex process of de-essing/ducking the exact frequency range of the hi-hats high frequency content. Thus my master sounds duller and has less air than several others. However, I feel this compromise was necessary and actually quite like my own master, it is my favourite of the bunch. Selfish? Perhaps.
