The single-ended A monoblocks E4 pursue a goal that all VALVET amplifiers strive for: the purest and most unmanipulated transmission of music that touches the senses! A simple but sophisticated circuit, short signal paths and the best, long-lasting components ensure that your favorite artist reaches you very directly. Maximum long-term listening pleasure!

The E4 mono power amplifiers have an output power of 12 watts at 8 ohms and 20 watts at 4 ohms. This doesn’t seem like much at first glance, but these power amplifiers can also do amazing things on speakers with an efficiency of 89 dB. The p

ower amplifiers work in single-ended A operation and only with a single power transistor in the output. We are of the opinion that connecting several power transistors in parallel to increase performance results in sound disadvantages. A good single-ended A design conveys music with a charm that other power amplifier concepts rarely or never achieve. The VALVET E4 offerthe sound quality of a single-ended A tube amplifier without its disadvantages (tube wear, poor bass control).

For those interested in technology: a very quiet 500 VA toroidal transformer, 4 ultra-fast 60 A individual diodes as rectifiers and a filter with 4TTN electrolytic capacitors from Supertech ensure ultra-stable operation. Extremely short (pure silver) signal paths.New, discrete operational amplifiers in Class A operation.

The sound: dynamic, neutral, balanced, very musical, powerful with a lot of blackness and control in the bass and simply harmonious. In the current version, detailed i

mprovements in mechanics, technology and sound ensure an even more harmonious package.These amps really sing!
