Rogers Reinvents E20a Integrated Amplifier for 2021
Some twenty-six years have passed since iconic British hi-fi manufacturer Rogers released its E20a integrated, the perfect match for its famous LS3/5a monitor loudspeakers at the time.
Today, Rogers has reinvented that classic and dubbed it E20a/ii, to perfectly complement the new “Reborn” LS3/5a Classic and LS5/9 Classic loudspeakers.
Based around the existing circuit and Push-Pull 6L6 output valves, Rogers tells us that the new E20a/ii has an updated circuit design and still operates in pure class A, “to provide a vivid, dynamic and wholly musical performance.”
With a non-magnetic aluminium chassis and lid, and an 18mm rigid faceplate, this is said to minimise eddy currents for improved sound quality. All surfaces have also been anodised for high quality and long life.
The new E20a/ii has been refined to include larger higher quality output transformers “to deliver increased dynamics and phenomenal bass response.” Additional features include silver-plated output speaker terminals, gold plated, chassis-mounted phono sockets, which are hard-wired for optimum low-level signal transfer. The PCB mountings have also been decoupled to minimise microphonic resonance.
The Rogers E20a/ii is available in two versions- Line, and Phono. Inputs include 4 line inputs, Line 1 operating as either MM Phone or an additional line input depending on the model chosen. You can also special order a model with a single-ended line output for connection to external amplifiers. The valve complement includes 4 x 6L6GT (output), 2 x 6SN7 (phase splitter), 1 x 12AX7 (anode follower), and 2 x 12AX7 (phono stage). Output power is rated at 18 Watts per channel Class A at 8 Ohms 1KHz 3% THD. The auto-biasing circuit will also prolong the vacuum tube life.
Available now, the Rogers E20a/ii integrated amplifier sells for $7,400 RRP (Line Version), or $8,400 RRP (Line/Phono Version).
