Goal is a wide open sound that's "alive" and draws me into the music. Bi-amping the Maggies was a huge step forward.
Front end rationale:
* Empire 208 turntable/Sonik Sircle tonearm -- this year's project was a major re-envisioning with a 1" aluminum baseplate + 3/8" steel + 2.25" MDF surrouned by a damped 3" thick walnut frame. About 90 lbs now.
* VPI Scout: probably the weakest link today, but nice for playing mono records with Ortofon 2M Mono cartridge
* Shelter 501-II cartridge is an easy listener, but could be a bit livelier.
* Dynavector DV20XL cartridge is dynamic, but could use more refinement.
* Modwright Transporter is simply great sounding. It was so good that I had to make significant upgrades to my vinyl playback to elevate it again
Amplification rationale:
* The First Sound Presence made a huge difference. Until I tube-rolled some frame-grid Amperexes, I found it a bit dry.
* The pair of Citation II amps were completely rebuilt using the Jim McShane mods and PIO caps for coupling and power supply bypass. They power the treble panels on the Maggies
* The Innersound ESL provides plenty of control and punch on the bass. The combination of bi-amping and speaker stands makes bass perform very well on the small Maggies.
Speakers:
* The Maggies work well in this room. They need a lot of space, and in stock form are somewhat veiled. Modding them brought them alive!
* When I connected the Maggie drivers directly to my amps, the illusion of presence was amazing! I had to roll up the socks to get to the original crossover & disconnect it, but it's completely reversable.
* The active crossover was custom built using the original Magneplanar asymetrical crossover points, and the Linkowitz labs MT1 module. The improvement over the crappy internal crossover was not subtle (as they say)
* the Audiokinesis SWARM subwoofer system cancels all the bass unevenness of my previous sub. Great bass anywhere in the room.
Overall I'm satisfied enough that I'm putting most of my money into software these days, rather than hardware. Bi-amping has been a nice change, and ultimately more rewarding.
The room is a wreck (man-cave) but the sound is terrific. Very happy.
Generates exact frequencies needed to keep the Papst motor on speed in the Empire
VPI Industries Scout
11-years old, still sounding great with Ortofon 2M Mono cartridge
Phoenix Engineering Falcon digital motor controller
clean 60hz signal for keeping the VPI exactly on speed. Instant switch to 45rpm.
Aesthetix Rhea
Rich and rewarding, puts meat on bones. Requires tube rolling to get it quiet, but very worthwhile. Looking forward to Signature upgrade
Modwright Transporter

First Sound Presence Deluxe Mk-II
Newest component
Linkowitz Labs MT1 Custom Crossover (active)
Replaces the crossover in the Magneplanars allowing direct connection of the driver elements, one element per amp channel
Harman Kardon Citation II
Extremely high bandwidth vintage amps, highly modified. Pair (2 amps) run as monoblocks 120wpc. Completely rebuilt using Jim McShane upgrades for power supply, grounding, and PIO caps; makes a terrific treble/mid amp for Maggies
Innersound Electrostatic
ESL300 amp used to power bass panels on Maggies
Magnepan MG-1.6qr, Biamped, w. Mye Stands
Bi-amp with custom active crossover: Citation on treble panel, Innersound on bass. Big improvement also when adding Mye stands! More solid bass. i almost never use the sub any more.
Audiokinesis Swarm
Distributed 4-sub system for pairing with planar speakers, designed and built by Duke LeJune
Speltz Anti-Cables
two pairs of magwire cables, one for each speaker driver element connected directly to each amp (bypassing the internal crossover)
Analysis Plus Copper Ovals
does little wrong; used throughout the system
Sound Design 5-shelf

Behringer DEQ2496
Used for examining room modes, and as an A/D convertor for burning LP's to CD-R
Philips CDR-870
Used to burn audio CD-R's from LP's so I can listen to my music in the car
