Hello, Totally new to Head-Fi. I have been using an HD800/WA7 for the last three years. I was an early Stax adopter back in 1970 and have always hankered back to that sound. So last week took delivery of 009s and STM-007tA (I currently live in Tokyo). Love the 009 presentation, but keep reading about BHSE and Carbons. My question is is the SRM-tA so bad or will I really appreciate the difference a BHSE/Carbon will make? Apologies if this has been covered before.
