I first bought a 200 Jeil 2000F (300) in 1999 for my 500Xt, then I bought the boxes and you had to push a little more.

Bought in 2000 4000F (600) I used a lot for me Systm Peavey 500XT 500 XT + Sub.
2 * 400W RMS into 4 ohms (that's a I use it)
and about 2 * 270 W into 8 ohms.
No bridge mode ... do not like 2 ohms.
Symtrique XLR input and output terminals Screw + banana.

500Xt with only finds its limits because of impdance Peavey in the low is quite low and therefore the amp more easily climb into the red.
As with all head against + box it behaves Fawn IDAL and the LED lights clip ever.

The tough ... nothing to do with the amps boost, ghost or other!
No breath.

Practice, the faade is lightweight which allows withdrawal of being protected by the potentiomtre faade.

Effective ventilation with removable cleanable filter dusts water.

Super Amp for me. c'tait again if I buy a flight case for being protected in transport ... which would have seen some nice scratch marks and dents.
Anyway, strictly speaking the amp still works great!

I have always found that my set has great sound ... much better than the plupars disomobiles.
