Published on 10/01/14 at 09:46 (This content has been automatically translated from French)I use it for almost 35 years (with JBL L00 Century) .modifié recent years by replacing the power supply capacitors (70v aluminum by the same capa still gives it more dynamic bass) and a quit Upgrade (hobby electronics) which readjusted the overly sensitive input gain a little behind and changes the amp ops. Already at the time this amp is considered one of the best and most neutral market now even fabuleux.et so strong that I even used to do in PA circuits blacken !!!!

22hh22Wonderful device!
Published on 05/07/14 at 10:27 (This content has been automatically translated from French)I have this wonderful amp since 1976, so it has been 38 years! Never fails, of course.
The sound is extraordinary natural and balance. I compared various amps (two good Marantz which one operating in class A, JVC quite some a Sansui - model AT 555A which had its heyday - and NAD). Quad flew over; it is simply out of competition. Listening gives an impression of perfection.
The unit is mounted on a granite slab 2 cm thick. This allows for better readability serious. A comparison "with and without" is instantly uplifting.
No doubt I'll have to check the capacitors to avoid any unpleasant surprises.
This amp is highly recommendable occasion!

Fred160656The "thread" that amplifies
Published on 06/18/11 at 02:41 (This content has been automatically translated from French)I own this amp since 1977 (it said) was revised (changing the power supply capacitors there are now seven or eight years.
It's indestructible, transparent, accurate, it is so neutral that have used it for years to amplify Studio Monitor liabilities (before buying recently active monitors) but it's always a real happiness that amplifies my Hifi speakers.
Another big advantage is that it can accept any type of load (it can easily supply the electrostatic speakers or speakers equipped with the same traditional happiness).
We still used from time to time and it is always possible to do by refurbishing QUAD UK or one of those authorized distributor.
34 years of good and loyal service...…

34 years of good and loyal service ... in retrospect it was worth the investment!
