ill post pics later next week when i get the film
lol are u seriously trying to compare the rs1's to the sr-255? have u even listened to the rs1 or are u just basing your opinion from reading specs online? i actually listened to all the sennheisers and rs1's and rs1's just sound better, the $300 sennheiser's came close but the rs1's had better high's imo
dont mistake the rs1 for some cheap set of headphones, they are the the roylce royce of headphones...same thing with the amp...i didnt compare many amps just some $400 one and the ra1 battery amp...i didnt notice much of a difference, both cleared up any screetchiness in the high's and made the bass warmer, and im not saying the headphones alone sounded bad, you dont even notice the imperfections until u use the amp and then go ampless
cant really argue about sound online, you need to listen to a nice instrumental cd or vinyl.
about pink floyd vinyls, of course, check on ebay if no where else.
