hey guys, i am looking at getting the Proton USB dac and i will be mainly listening to rock music like Grand Funk, Yes, Deep Purple, now i was wondering if anyone has any experience using this dac with this king of genre? I actually went to listen to it in one of the stores here, but they have a jazz optimized room and equipment there with tube preamps etc, which didn't really produce much of a heavy sound on my type of music, I just want to know if this will be a good choice? Thanks
