The X4000 amps are no slouch they sound great, but the AVR-4520ci has separate amp stages on individual cards, linked to a heat sink. It's just a nicer, isolated design that can produce way more power with less distortion.
The X4000 would make a GREAT pre-amp, only issue of course is it can only handle 9.2 not 11.2 like the AVR-4520ci (if that matters to you?)
As for your last question, it depends on you, your tastes, supporting equipment, and your internal trade off of cost versus benefit.
Personally, if someone said they were going to get a X4000 and do a budget amp right now (Such as a Emotiva XPA-5), the price would be VERY close to a AVR-4520ci.
I honestly don't know what my recommendation would be in that case, both have benefits and trade offs, it depends what your plans for the room is.
Personally after hearing the Marantz amps, I would love to get the AV8801 with balanced, and go all out with their 7 channel and 5 channel setup. I think that setup would be around $6k. Is it $4k better then a AVR-4520ci . . I don't know . . . each person has to answer that based on their own budget.One last statement I can say though, since I own both of these setups. YOU CAN'T GO WRONG WITH EITHER.
