Product Description

Quad proudly present their stunning Quad II Classic Integrated - a balanced and fully integrated amplifier, combining high performance with a compact enclosure of classic design. As could be expected of one of the most famous names in hifi, the performance of the QUAD II Classic Integrated is exceptional in every way.

The specified 25 Watts per channel is sufficient to drive and control even the most demanding speakers. The remarkable output transformer ( a design by audio legend Tim DeParavicini) delivers speed, sophistication, and above all the ability to reproduce your music like a live performance.

All in all this is a real Quad amplifier: the closest approach to the original sound.

Supplied in the beautiful champagne finish pictured. A perfect match for many speakers including Quad ESL 2805 or ESL 2905 electrostatics. Please contact us for advice if you are interested in a complete Quad system.

Press Reviews

  • The Quad II Classic is a fine integrated amplifier that misses out on that fifth star by the narrowest of sonic margins and a hefty price tag. Its appearance apes the Quad products of the past, but, in sonic attitude, it sounds as modern as valve amplifiers get. There's plenty of drive and energy – both qualities similar designs fail to deliver. Few valve integrated amps have punch, but this one does. The Quad II has a built-in phono stage, which is something of a rarity at this price level. (What Hi-Fi Magazine)
