|Amplifier:||6 x AKSA monobloc power amps for active tri-amping. Each side has 25w/55w/100w (into 8 ohms) amp modules.|
|Preamplifier (or None if Integrated):||AKSA GK-2R remote-controlled, tube/ss hybrid pre-amp. With TKD stepped attenuator upgrade.|
|Speakers:||Maggie IIIAs for 20 years. Replaced in mid 2010 with "Frankenpans" - a 'mongrel' Maggie which is, in effect, a IIIA which has the mid driver on a separate sheet of mylar to the bass driver.|
This allows me to isolate the mid driver & ribbon from vibrations created by the bass driver ... and stops IM distortion happening, between bass & mid drivers.
Bass drivers came from some MG-2.5s; mids & ribbons came from a T-IVa. Drivers are mounted in hardwood frames - 2 per side (1 for the bass driver; 1 for the mid & ribbon).
Each frame is mounted on its own 1.5" thick spiked plinth, which enables the frames to be placed in an arc - so they are effectively time aligned. The mid/ribbon panels are currently angled to point at my ears, while the bass panels (which are on the inside) are almost flat to the wall. I therefore have to move the inner frames slightly back, to keep all of them equidistant from my ears.
|CD Player/DAC:||H-K CDR-20 for recording my LPs (for the car!).|
|Turntable/Phono Stage:||Linn LP12 with Khan top-plate, Lingo 2/Graham 2.2 arm/Benz Ebony LP cartridge. Cetech CF-composite subchassis and armboard on the LP12 plus, recently, a custom-made plinth.|
Bill Beard BBP100 discrete ss phono stage with new power supply.
|Other Source(s):||Yamaha T2 FM tuner.|
|Speaker Cables/Interconnects:||Currently nothing special.|
Some ICs from 'The Super Cable Cookbook' put out by Allen Wright (Vacuum State Electronics). Each channel consist of 2 strands of XLO Teflon-insulated, solid-core Cu wrapped around a 4mm teflon tube ... kinda like a 'lightweight racing' XLO.
|Other (Power Conditioner, Racks etc.):||Nitty Gritty RCM.|
DIY isolation platforms for phonostage and preamp. These consist of a 15kg slab of slate resting on 8 squash balls (see www.enjoythemusic.com for the basic idea).
