We set about designing our first Integra integrated amp many years ago.  At the time we wanted to make an amplifier that didn’t compromise sound quality due to being a one box set up rather than our normal pre/power amp designs.  This version of the Integra uses 211 valves and continues that “no compromise” philosophy. In fact, the 211 was originally designed for radio transmitters and has excellent linearity. This means in an audio amplifier, at the lower frequencies  involved, it can can have very low feedback (6dB) leading to low distortion, and a very musical sound.

in fact the sound quality of the 211 is noted for many positive aspects.  The tonality, pace, rhythm, timing, bass, dynamics and soundstage are often said to feel so real, you feel like you are in the room with the band. One fan said “They have that ‘you are there’ live quality to their sound”.

The Art Audio Integra 211 uses these valves combined with the very best components for the job and a high quality chassis combining great sound with great looks. Due to the use of our electronic biasing system, they are truly plug and play devices, enabling the user to always get the best, most musical sound from the unit
