Sunfire Signature... what is this?


Recently bought a Sunfire Signature amp, believing I was getting the 600x2 model. The front panel has "Sunfire" above the Joules meter, and "Load Invariant High Fidelity Stereo Power Amplifier" below. A Bob Carver signature is on the upper left of the panel. The rear panel has "Sunfire Signature" just above the serial number (which starts with 99), and a lot of the other normal printing. The two speaker fuses are labeled "5 Amp SLO-BLO MDL/Q", and the AC line fuse is labeled "10 AMP MDA-10 120 VAC", which makes me question if this is a Sig-600. Any thoughts?

How high does the meter peg out at? Should be either 380 joules or 480 joules.
The needle goes nearly to the 500... 450+ for sure, but I read that there was an adjustment pot for the meter on a board in the amp. I have a Sunfire Cinema Grand (405x5) that has 6-amp MDQ-6 fuses on each channel, which also leads me to suspect this amp is not 600w/channel.
If it says Signature on the back and has his signature on the front face as you say then it is surely a Sig 600. He did not make a Sig 300 etc....

If the binding posts have the red and black plastic covers, then it is a first generation. If the solid steel posts with an IEC, then the second version.

The 600 is very powerful and you should notice this immediately in your system.
