I think the individual component descriptions say most of it. Also pertinent: dedicated 20-amp AC line with Hubbell hospital-grade duplex outlets; Torus RM20 isolation transformer/surge protector on the way.

Although there are "bigger rigs" in the bedroom and living room, this is the one which logs the most playing hours, because it's in my home office where I toil (independent scholar of Buddhist studies and freelance editor/translator) day in and day out. I'd describe the system as having good resolution, excellent dynamics, limited but quality bass, and slightly "warmer" overall than many solid-state setups, due to both the pre- and power amps.

Room acoustics suck (wood floors, wood-panelled and plaster walls, but it's above all a work space, so no anxiety there. Does well on everything from Persian classical to heavy roots dub.

The only upgrade plans I have are as mentioned: the Torus isolation transformer. I've got one in the living room system and the improvements in clarity and low-level detail are comparable to a component upgrade. Beyond that, I may take the transport in to a local modder with whom I've worked before for power supply and digital output circuitry upgrades (cf. Empirical Audio)--or copy all my discs onto a Mac Mini and press into service the Empirical Audio Off-Ramp USB-to-XLR converter that sits in the closet.
