I'd choose the Sony, because if I were using this in an audio-based system I'd want the best possible performance and the Sony is probably easier to get modified. I'd have someone like Ric Schultz(www.tweakaudio.com), Dan Wright, or Stan Warren turn it into a killer for a few hundred bucks. I wouldn't be thrilled with either one of them in stock form for serious listening. Best of luck.
