Built my first stereo from a Kenwood kit when I was 12. Been morphing through different system configs all my life. Current setup: B&W 803 floorstanders backed up by an REL T9 sub. Power is a Bryston 3B. I use a fully restored Sansui 999 as my preamp. ROON is on a MacBook Pro with an attached 8TB library. Sources: TIDAL (of course), Technics CD Player, Original Sony Minidisc (yep! you read that right), Pro-Ject turntable. DAC is a USB Dragonfly Black. Sorry folks - no bitcoin fuelled six figure components. As a sideline, I help folks build great sounding inexpensive systems using a mix of vintage & modern.
