the last setup worked out pretty nice with the Sony zx-507. i suppose of course things work out with batteries being the way they are so as much as they have power, considerably you can make more ideal changes in listening experience in the window setup for flac formats. i put the high gain option for stereo mini jack on and the direct source option on and it turns out i can fit my mind around the music for some time to put my mind to the test of making up more weighty thoughts on a reall good setup with gauss this time. with a high battery output gauss can give a real technical feel for the acoustics coming out with a aword for that would be like, actually ... just having the guitar being further within the listening boundary whereas the proper output of the phones have for so much to keep the distortion in a sort of finger to hand empiricism. the music can really get good and gauss seems to make out a more techinical aspect to the phones with acoustics and distortion in rock songs because i tend to make up some listening and i can feel around for a good amount of spurt for thinking my way up to putting gauss for amounts of processing the next supposing setup.
