ROGERS ARE SHOWING THE UPDATED VERSION OF THEIR E20A VALVE AMPLIFIER AT BRISTOL

The new Rogers E20a/ii Valve Amplifier has been designed to complement their LS3/5A Loudspeakers, launched in 2020 it makes its way to Bristol this year.

The Rogers E20a/ii is the first model in a new series of valve amplifiers from Rogers, which includes the ten model limited run Rogers E40a/iiLE integrated amplifier.

ROGERS E20A/II VALVE AMPLIFIER

The E20a now has a special 8/15 Ohm output transformer specifically designed to drive LS3/5A’s. Originally conceived in 1995, the original Rogers E20a’s was designed to drive the Rogers LS3/5a loudspeakers to the highest possible sound quality, perfectly blending the “then” modern digital era with Class A and valve technology.

Fast forward to 2020 and Rogers extensively revised the original E20a into the new E20a/ii to complement the new “Reborn” LS3/5a Classic and LS5/9 Classic loudspeakers. Now they are able to show it at the first Bristol HiFi Show since the Covid pandemic saw the last two year’s shows cancelled.

Based around the existing circuit and Push-Pull 6L6 output valves, the new E20a/ii has an updated circuit design and still operates in pure class A. Rogers says that optimizing the transformer matching to the LS3/5A impedance greatly improves the performance of the LS3/5A.
