I have two systems for one simple reason: I like to listen to music while I work (home office system) as well as while I'm not (living room system). In my case, I have no TV and, obviously, no home theatre. Both my systems are plain, two-channel audio.
LR System: Thorens TD-125 mk II with Grace 707 arm, Reson Reca cartridge; Sony X779ES CD player; SAE tuner; Meitner PA-6i preamp; Meitner MTR-101 monoblocs; Tannoy System 12 DMT II speakers; Museatex cryogenic interconnects and speaker cable.
By no means ultra high-end, price-wise (everything but phono cartridge and some cables purchased used), but satisfies me.
Office System: Pioneer PD-91 (as transport); Monarchy 18B DAC; Bryston 11B preamp; Meitner STR-55 power amp; Tannoy System 12 DMT I speakers; XLO Pro 1200 speaker cable; Belden and Canare StarQuad cables for interconnects.
