Art Audio Opus 2 EL34 Stereo Power Amplifier
Frequently Bought Together
Product Overview & Specifications
The Opus 2 Has the same classic EL34 circuit Art's started using in Art first design , The Quintet in 1988. Tried tested, trusted and loved by customers all over the world, this design has stood the test of time and is still one of Art most popular models.
Two versions are available.
One for higher power 25 watts (Pentode), the other for optimum sound quality 15 watts (triode). The sound is enticing and the longer you listen to this amp the more you will appreciate its easy grace and effortless musicality.
The Quintet was once described by Chris Binns as the poor mans Jardis!
The Opus 2 gives you music with a sense of rightness that you dont really question, you just get on and enjoy it.
With 15 watts Triode (low feedback) you need to use speakers around 98 db and above.
With 25 watts Pentode (higher feedback) you will get away with less efficient speakers around 95 db, slightly more dynamic than the triode version with tighter bass, but not quite so musical.
The Opus 2 can be further configured as a line level integrated or a power amplifier, further enhancing its versatility.
