LJC System – latest

LAST UPDATED December 19, 2022

Deceptively simple photo of the main components above conceals the spaghetti-hell behind the scenes – balanced mains supply, multiple power-conditioning units, filters and purifiers, circuit-noise neutralisers, earthing enhancers, empty-socket stops, all working together to enable the front-end components to shine.

UPGRADE HISTORY

Cartridge Upgrade, November 2022: Dynavector XV1T

Flagship of the Dynavector range, astonishing presence and energy, imagery, stupendous.

Valve power amplifier September 2022

World Designs KT 88 custom – build

Custom-built World Designs KT 88 valve amp, fitted with Psvane KT88-T Mk2 valves, Black Gate capacitors, Furutech power socket, circuit and transformer designs by Andy Grove of Audio Note, component upgrades curated by Man-In-A-Shed, lovingly hand-built by Mathew Snell, World Designs.

The output of this valve amp is only 35 watts compared with the Linn’s 200 watts, yet it powers quite comfortable the Linn 242 speakers, the last remaining legacy Linn components. The volume control remains at a similar one quarter turn setting, showing how much redundant surplus power capacity was designed in the solid-state amp.

It sounds…gorgeous, organic, transparent, effortless…breathing freely. Pity it requires a half-hour valve warm up to reach that level, but that is a small price to pay.

The staging has been replaced by an Atacama Eris Eco 2, which is the only commercially available system that meets my minimal space footprint.

OUT – Solid state Linn C4200 power amplifier

Relocating the Avid Acutus Reference PSU up a rack stage permitted reuse of a higher quality but shorter (0.5m) interconnect Kimber 1036 between the preamp and amp, matching the critical cable from the TT to the Phono amp

OUT – the Linn Akurate Digital Streamer. Control device upgrades required, money wasted on Ipad2, fussy database management, no longer supported operating system, not worth trying to keep up. Linn is concentrating on multi-room connectivity, phone-docking stations, and digital streaming services. Next stop hi-fi IKEA, Bang and Olufson. The pied piper of convenience and unlimited choice wins, the audiophile loses. LJC is now all analog, vinyl only, bye bye Linn, once great company.

MORE VOODOO

Power Conditioning – AbZorbers

I already had three of these devices in place but adding a fourth AbZorber represented a breakthrough in clarity and realism of the whole spectrum of sound. No idea how they work, reducing the effect of voltage spikes which impair transformer operation and generate background noise, apparently. I just know they make a huge difference to the quality of mains power supply

Furutech High End Performance Rhodium-plated fuses

Every power cable (10 of them) is fitted with Furutech Rhodium-plated T13A fuses, all power-plugs are upgraded to Rhodium plated connectors. The difference rhodium plating make defies reason, but hearing is believing. (Warning: these glass-bodied fuses are not available for sale in the UK)

“The T13A features a glass body specially tuned for resonance control, pure silver conductor wire precisely calibrated for its rated capacity, and rhodium plated pure copper end caps for increased conductivity and protection from corrosion. Widely regarded as one of the best UK fuses available, this will bring a considerable improvement to sound quality in most high-end audio systems. Furutech have since ceased production of these fuses, consequently making them highly sought after.”

WHAT NEXT?

Effort now goes on listening to records in the collection rather than adding yet more.
