Homebrew rack made from scrap lumber

Room Size (LxWxH): 25 x 10 x 10
Room Comments/Treatments: Turntables installed on super-heavy credenza against back wall of a long living room. Room can be divided by glass doors.
Music Preferences and Comments:
Music Used (Genre/Selections): Jazz/Funk/Soul/Disco classics

Lots of old school and contemporary hip-hop

System Goals/Comments: This is a practice system for a learning bedroom DJ. It is also used for a hi-fi setup and home studio. Eventually it will be made modular for installation in a van for a Mobile DJ/Sound System setup.
System Strengths: 60W of total tube power split three ways - two full band channels and one sub-bass fed to amps by crossover unit. Over 110dB peak @ 1khz measured on an SPL meter. This system gets the most out of dance music with heavy bass, clean mids and crisp highs - used SPL meter to tweak response curve flat @ 90dB using test tones and EQ unit. Never fails to impress my stereo-in-a-box friends.
System Weaknesses: Probably not officially hi-fidelity because of Shure DJ-style cartridge, solid-state preamp/mixer, cheaper push-pull style tube amps - this is for listening to James Brown, not Fleetwood Mac.
Video/HT System: Integrated
TV/Projector: Hitachi 32" TV
Processor/Receiver/Amplifiers: 30WPC internal amp w/line out and speaker posts (occassionally used as backup).
Speakers (Center, Surrounds, Sub): Patched to audio setup through Vestax mixer
Sources (DVD/VCR): Antenna (RF), Stereo VHS VCR (RCA Composite), Canon ZR-20 DV camera (S-Video LCr)
Comments on HT System: Largely for casual viewing, occasionally used as monitor for video editing using Final Cut Pro on iMac. Canon ZR-20 used to convert Firewire DV to S-Video.
