I stopped replacing my stuff 15 years ago, with the exception of digital players which have continually evolved. Right now my setup is:
- Logitech Media Player
- Technics SL-D202 Turntable
- Nakamichi Dragon Deck
- Nikko Beta III Preamp
- Adcom 535-2 Amp
- NHT Super Zeros paired with SW2P Subwoofer.
The only piece I'm not that happy with is the Logitech, but I'm not willing to spend audiophile money on a digital network player.
I would love to modify my room acoustically, but the lack of WAF for such changes has always trumped my wants.
