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.
