About the CAD-805AE Amplifier

Single-end triode (SET) tube amplifiers have long been considered the Holy Grail of music reproduction systems, operating in the purest form of class-A power output. Cary Audio began in 1989 by producing a SET monoblock amplifier as its first product, and today the CAD-805AE proudly carries on that tradition. Using just one tube to handle the entire musical signal typically does not allow for more than a few watts of output power, but the CAD-805AE, with its massive power supply, is able to produce over 50 watts.

Cary Audio always hand-builds their tube products and carefully matches the tubes. In the case of the CAD-805AE monoblocks, this even extends to giving you two very different types of output tubes as standard. These two tubes have a quite different sonic character from each other, and by giving you both you can fine tune your system to best match your musical taste, your speakers, and your room’s acoustic signature. A pair of these monoblocks represent the pinnacle of today’s tube design capability, and will make your system sing as never before. If you want the very best and most accurate musical response in your home, audition the CAD-805AE.
