Vandersteen 2Ce ,
Thiel CS1.2 ,
sometimes all selectable with Adcom GFS-3 speaker selector switch.
|CD Player/DAC:||Sony BDP-S350|
|Other Source(s):||Computer, IPOD|
|Speaker Cables/Interconnects:||14 AWG zip cord for MG-12/QR|
14 AWG zip cord, bi-wired, for Vandersteen 2Ce
|Other (Power Conditioner, Racks etc.):||Superlux ECM999 Measurement Microphone,|
A.R.T. TubeMPStudio Mic Preamp,
|Tweaks:||Replaced the electrolytic capacitor in the bass section of the crossover of ONE MG-12, only, with a polypropylene cap. Currently attempting to measure differences between modded and un-modded MG-12 speakers. But I can definitely HEAR the difference.|
Keeping the tweeter fuses in the MG-12s! Blew them both at once when the preamp's motorized volume knob got "stuck" in clockwise mode!
|Room Size (LxWxH):||12 x 20 x 8|
|Room Comments/Treatments:||Currently listening position is on couch at center of long wall, with speakers about 1/3 of the way across the room from both the front wall and the side walls, toed-in to cross just behind listening position. Have floor-to-ceiling curtain (about 4 feet wide) behind each speaker. usually keep the Vandersteens against the inboard sides of the MG-12s, which greatly-enhances bass from MG-12s. (Vandersteens are not usually connected to anything. They just block reflections).|
|Music Preferences and Comments:|
|Music Used (Genre/Selections):||Classical, Classic Rock, Jazz, just about anything except Rap and old-style twangy country/western|
|System Goals/Comments:||Goal: MG-3.X or IIIa, or, Tympanis|
Another goal: to try bi-amping or tri-amping with an active small-signal crossover before the power amps.
|System Strengths:||Sound is exquisite. Frequency response measures very flat at the listening position. Even the bass from MG-12 speakers is astoundingly great.|
|System Weaknesses:||It would be nice if the MG-12/QR speakers could play a little more loudly before they start to self-distort.|
|Video/HT System: None|
|Other Interests/Hobbies/Occupation:||Electrical engineer. Enjoy the Electronic Warfare field. Also enjoy automatic weapon-delivery systems, statistical pattern recognition, designing audio amps, refurbing older test equipment and antique tube gear, my 10-inch Newtonian reflector telescope, and cherish "wine, women, and song".|
