US$550 is a fair-to-slightly-strong asking price, sitting above the US$475 median but below the US$582 75th percentile for recent comparable listings. It is not a bargain, but it is defensible if the unit is clean and complete; with an unknown condition, a little negotiation would be sensible.
The PA7 Plus is a compact, powerful Class D amplifier with balanced XLR/TRS and RCA inputs, a defeatable volume control, 12V trigger, and roughly 135W per channel into 8 ohms or 245W into 4 ohms at 1% distortion. It is well suited to demanding bookshelf or small-to-medium floorstanding speakers and can serve as either a standalone control amp or a power amp. Confirm that the substantial external power supply, power cable, and trigger functionality are included before paying the upper half of the range.
