Several similarities indeed! Yes, my handle is named after my 2001 Trek 5500. I put many, many miles on that bike. Sadly it doesn't get ridden as much as I'd like these days. Over the years I've had several speakers from NHT in and out of the system. At some point I was running the original Super Zeros with the SW2Pi subwoofer. I think all together I owned the Super Zero's on three separate occasions. I always liked their products, but haven't heard anything they've made since the classic Two, Three and Four.
