The Great Little Valve Company proudly presents the EQ1-S…

The only Hi-End, Pure Valve, Stereo, Active Audio Enhancement & Tone Control system for use in the home, studio or live sound.

Whatever your thoughts on the digital vs analogue debate, music is all about how it makes you feel and when it comes to listening to music in the home there are many reasons to use tone controls for music reproduction, especially in the todays’ complex digitally – dominated world of sound recording and reproduction.
However, the mainstream audio industry has for too long been disregarding the very real subjective experience of the listener in that, whilst being unique to each person, it is not measurable and therefore deemed irrelevant. Given all the digital technology we have today you would think we should be living in audio heaven, but it appears we are all suffering from digital distress syndrome!

Rather, increasing numbers of music Industry professionals, critics and audiophiles share the opinion that modern digitally recorded music is becoming more fatiguing to the listener and less engaging due to use of huge amounts of digital processing in the recording and mastering stages, which is having a huge effect on the listening experience and as a result the undeniable popularity of true analogue sound continues to soar.

The new  EQ1-S, from the Great Little Valve Company, was designed specifically for true music lovers and professionals alike to overcome the adverse effects of digital processing. Whether you are the owner of a hi-end audio system, home theatre or music studio the EQ1-S will enhance your music beyond belief,  resulting in a more emotive, enjoyable, rich, warm and engaging listening experience.

It’s not just analogue, it’s  High-Definition Analogue !
