See my main system for the origin and rationale of my audio setups.
This is my home office where I work and enjoy background music, mostly smooth Jazz or chamber music and occasionally watching (part) of a movie. It started out with bookshelves and later in wall speakers but my crave for Dunlavy coherent sound is simply too strong: enter the Dunlavy SC III that I acquired, just like all the other big speakers, locally.
Hence the title of Menage a trois. To be sure: Duntech Sovereign 2001, Duntech Black Knight, Dunlavy SC III, not somebody else in the household ;-)
Music sources are Amazon Prime Music and Foobar2000 accessing FLACs on the NAS, iFI DSD nano directly to the trusted Aragon 8008.
Cables are NordOst Valkyrja as IC, Western Electric 14ga DIY speaker cables and Western Electric 10ga DIY power cords. Audience aR2-T power conditioner.
The book cabinets along two walls ensure good dampening so no room treatment is needed. Heavy curtains covering the windows helps too.
With tweaks (Audio Magic Platinum fuse, BDR isolation devices, Audio Points footers, Schumann Resonator, etc) the sound has become very enjoyable and reaches the level of SQ like my main system 7 years ago.
