This beautifully crafted hand made amp is designed to deliver the wonderful sound of the original classic Marantz 8B amp with features and build quality that would not have been dreamed of in the 1960's or 1970's. Although many 'improvements' have happened to HiFi equipment, many purists still believe that Simple is Better. Classic, simple design of amplifiers, with the improvement that better capacitors and better connectors, and even creature comforts like Remote Control, will reproduce your music in an easier to listen to, less fatiguing way.
The Cayin Audio A-55T uses four KT88 Output Tubes(A-50T uses EL34 tubes, tube type is the only different between A-50T & A-55T models, all chassis marked at A-50T) for Class AB1 Push Pull Amplification. The craftsmanship is first rate, inside and outside. The torodial power transformer and EI output transformers are specially designed and manufactured for the Cayin A-55T. Our unique Soft-start circuit helps extend tube life (typically 3000 hours!). The removable cage snaps on and off anytime. Cover on has a clean classic look, cover off... Keep On Glowin'.
Once the cover is off the Bias adjustment controls and test points are easily accessible and adjustable from the top of the Chassis. (See Photos below) The amp is very stable and typically won't need a bias adjustment for about 1000 hours.
Check out the reviews of the A-50T:
"The A50T is an absolutely fabulous sounding amp. So don't let its price fool you!" - Robert Bantz, President of Elusive Disc, Inc.
"...the Cayin A-50T is competitive with many higher-powered, more expensive integrateds, both tube and solid-state, and its strengths rival those of many far more expensive tube separates I've heard. Finally, the 35Wpc A-50T behaves like an amplifier that puts out twice its rated power-or more. I strongly recommend that anyone considering spending up to $2000 on an integrated amplifier listen to the magic that the Cayin A-50T can produce." - Robert Reina, Stereophile, March 2008
"The Cayin A-50T is the best low-price amp I have ever heard, and it rivals some of the best amps in any price range." - Harry Weisfeld, owner of VPI Industries
Special Note: The Cayin A-50T and A-55T Integrated Amps are identical except for tubes... all chassis will say A-50T.
