Dear Friend:
Thank you for purchasing my SunÞre Cinema Grand Þve channel power ampliÞer. I hope you enjoy it and the music it makes as much as I have enjoyed creating it for you.
This magniÞcent ampliÞer represents my very latest thinking - and my best ampliÞer design ever. I’ve spent over twenty years developing it, and cannot imagine how I could make it any better, or reÞne it any further. No matter what, its perfor- mance is, at Þrst, somewhat difÞcult to believe.
The Signature 400~Þve can produce 400 watts rms per channel into 8 ohms and 800 watts rms into 4 ohms. The 200~Þve can produce 200 watts rms per channel into 8 ohms, and 400 watts rms into 4 ohms.
The big breakthrough feature of the Cinema Grand is its uncanny tracking downconverter, which uses 18 Herculean Mosfets in the Signature 400~Þve and 12 in the 200~Þve.
The circuit boards are heavy glass epoxy, double sided, with a Faraday shield on the back side. All resistors in the sig- nal path are 1% tolerance,
I could go on and on, but here’s the best part: I’ve included two kinds of outputs on the front left, right, and center :
(1)a standard
(2)a
Whichever way you decide to hook up the SunÞre Cinema Grand, it will create a multilayered soundstage that is deep, wide,
