Many Audiophiles have come to know the outstanding quality and value of the line of Icon Audio UK tube integrated amplifiers. We at Audioarcan (Canadian Distributor for Icon Audio) are pleased to add the Icon LA4 MKIII tube pre-amplifier to our product offerings. Whether you are pairing the LA4 MKIII Standard or Upgraded Signature with solid state or tube amplifier you will realize outstanding sonic rewards.

A line pre-amp of outstanding quality Building on the success of the earlier marques, the LA4 MKIII has improved cosmetics and an upgraded circuit. Now with lower feedback and lower gain the macro dynamics and sound stage are enhanced. A deceptively simple high quality single stage design followed by an output buffer. But what makes the LA4 III special is the power supply and our “finely tuned” design. A high end pre amplifier must have the best power supply. The LA4 MK III has two chokes in double Pi configuration for well conditioned power giving superb smoothing for velvety inky black silence. The rectifier valve, which makes a surprising difference, is the excellent GZ34. This outstanding Western Electric design is probably the best sounding power valve available. The three audio valves we use are the 6SN7 double triodes. This 1940 vintage valve has all the best characteristics for the job, and its larger size means long life and good stability. Also the sound is more musical as we feel these have a more fluid sound. You can experiment with both vintage and modern types. Built to last Like all our equipment the LA4 III is very solidly made. It has a heavy alloy and steel chassis. The internal wiring is all “point to point”, “hand wired”, this is essential for valve amplifiers, and allows for upgrading to larger capacitors, and makes future servicing very simple. Summary: Very simple high quality line pre-amp. Ideal for virtually any kind of power amplifier. * FREE SHIPPING TAX INC. ** TWO YEAR WARRNTY *

Icon Audio LA4 MkIII Signature

$2,995 (standard version, $2495)

The LA4’s classic recipe consists of a 6SN7 gain stage, a tube buffer, a tube-rectified power supply, and point-to-point wiring. This elemental combination, together with excellent engineering, makes the LA4 Signature into a formidable line preamp. Tonal colors are reproduced with superb fidelity, vibrant and engaging. Dynamic shadings are nicely drawn out from soft to very loud. Although the stock tube complement isn’t particularly romantic sounding, it is responsible for exceptional bass definition and iconic 3D rendering of the soundstage. The LA4’s most compelling sonic attribute is tonal gravitas—an authoritative portrayal of the lower midrange, delivered with realistic tonal density. In all, the LA4 offers exceptional sound quality that does justice to the sonic promise of the 6SN7. DO, 322
