Quad 909 / 707 / 606 mk2 Power Amp - Upgrade
The 909 / 707 / 606 mk2 are very capable amplifiers that punches above its weight. With this upgrade we remove a few audio veils. Treble is more open yet less splashy, midrange is less muddled and transparent and bass gains much more texture. All together the sense of width and space is apparent.

Brent upgraded the Quad 99 CD player and Quad 909 power amp. I was pleased
with the Quad‘s original sound hence me purchasing them. The upgrades have
lifted them both to another higher level. It’s a cliché however I am
hearing sounds I have not previously heard.
I am listening to familiar music from the last 50 years and the sound is
audibly clearer and cleaner, although instruments and vocals are expected
they surprise me with their sharpness and suddenness.
Music is giving me shivers and goose bumps.
My son summed it up when he stated ‘Wow its clear isn’t it’
