Product Review - Sunfire Cinema Grand Signature Five-Channel Power Amplifier - September, 1999 - Updated November, 2001 Product Review - Sunfire Cinema Grand Signature Five-Channel Power Amplifier - September, 1999 - Updated November, 2001 John E. Sunfire Cinema Grand Signature Five-Channel Power Amplifier 405 Watts rms per Channel into 8 Ohms MFR: 1 Hz - 80 kHz Input Impedance: 24 kOhm Size: 6 1/2' H x 19' W x 16 3/4' D Weight: 43 pounds MSRP: $3,495 USA ($3,750 in 2001, See Below) Sunfire Corporation, 5210 Bickford Avenue Snohomish, Washington 98290; Phone 425-335-4748; Fax 425-335-4746; Web. The first thing I want to say is, 'This is not your Grandfather's amplifier.'

In those days, commercial movie theaters made do with 10 watts or less, and that was just with one channel. Mobogenie Setup 2 1 13 5 Exe. Those days are GONE! Underneath the hood of the Sunfire Cinema Grand Signature are more than 400 watts rms x 5, just waiting for you to make the windows shudder.

Just waiting for your neighbor to make the big mistake of thinking his home theater is more powerful than yours. The Signature is Bob Carver's latest addition to the Sunfire brand of hi-fi, and he told me he thinks it is his best work yet. After listening to it, I believe him. Note: This product has been upgraded with a larger power supply. See November, 2001 review at bottom of page. It looks like many of Sunfire's other products.

Bob has always given his customers a huge bang for the buck, and by using the same chassis cover for several different products, with only the printed name of the model on the front being different, he saves money. And that saving gets passed on to us. Another thing we save is energy. The Cinema Grand Signature uses a digital switching power supply (Class D), courtesy of Bob's Tracking Downconverter. This circuit maintains the rail voltage just 6 volts above the signal demands, and that makes the power supply very efficient... In other words, it 'tracks' the signal voltage and keeps the supply just above it. For the Sunfire, the tracking downconverter is making adjustments 130,000 times per second, which is more than 6 times per second at the top end of the audible spectrum (20 kHz).
