I would hesitate to spend that much money on a JVC product. What other products have you short listed for review?
In terms of amplifier stages in any product (amp, integrated or receiver) the power supply and output devices. Well designed amps require very sturdy power supplies to maintain quality, stable output. Output stages should be of quality electronics, with transistor output stages being superior to all IC based designs. (Tubes are another output device, but we won't venture into that territory here)
JVC MSRP for that piece is $1700, and that could get you into the Rotel, NAD area. These are better quality gear, far better designs than JVC/Pioneer/Yamaha, and above Onkyo/HK/Denon on most models.
Also, specifications should not be the main reason for purchasing any product. In some cases there are no defined standards for measurements. This can lead to confusion. There are other thread that deal with topics of specifications, and may be worth a read.
