My main System is quite special system to me. As you could see from picture I took my time to make sure what room is acoustically treated

I use bass traps in all corners as well as triangular pillows and absorbing pads. I have 8 diffraction pads on my side walls as well as 6 Argent Room Lenses. I use 2 "Rack of Silence" racks and each component on the rack sit on top of the "Feet of Silence". Racks itself sitting on top of the Osiris Giza bases.  Power conditioners sitting on Osiris Airiel Stands.

List of equipment:

.SilverLine Montechristo speakers - $50K,  800 lbs beasts standing 8' tall and with 98db of  sensitivity.

Just replaced all Thor Gear with VAC Phi Amps/Preamp

Woofers are driven by modified (Bob Cramps mods) Parasound 3500 which exhibits best control under 200Hz, easily outperforming large Krell amps in that area.

My digital chain consists of Forsell Air Reference Transport MKII - temporary under repair and replaced by Pioneer S-95, GW Labs upsampler and my new BREMEN License DAC

In my vinyl rig I use Forsell Air Reference MK III Turntable (with upgraded motor), Forsell Air Arm, Koetsu Onyx Long-body and Platinum cartridges

Just had custom set of Stealth cables - Sergey spend 4 days here helping me tweak and match. - So far best cable set I have NOT heard - they just do not call any attention to themselves

Power cords are Electraglide - I use Chingis Khan (monster) and  Fatman K. On digital I use Stealth Cloud 9.

 Just installed 3 dedicated power lines. I use 2 Shinyata Hydra power conditioners. Recently added  2 Audio Magic Stealth power conditioners. I also use 2 proprietary  AC sine wave regenerators on my digital front end.

Picture of my previous system

Meadowlark Ibis Speakers - 4 way design with active external x-over (require Bi-Amping) over 400 lbs each and go down flat to the 18 HZ(-3db at 16) and up to the 45KHz thanks to the Audax golden eye tweeters. I just added Sequera super-tweeters.  Ibis was custom made by Pat McKinney and is truly reference class speakers. They where recently internally rewired with Acoustic Zen cables. Crossover features external power supply
