choosing the best amplification for my setup

Hey guys,

My name is hagay and i'm from israel. i'm a long time reader but this is my first actual post at this forum. Currently, i don't have the space for two seperate systems (one for stereo and one for my home-theater) and i need an "allrounder" system that will handle anything i throw at it with style and grace.

I'm currently using a full set of Morel speakers - Morel Octave, siganture edition (including the sub units, center channel and rears) - please bare in mind that they are all 4 ohm speakers

also,for now, i'm using an Emotiva UMC-1 as a pre/processor (as a part of an upgrade plan for the future XMC-1 processor)

for amplification, i'm using an Audio Refinement multi-5 for the center channel and all the other surround speakers and until today i was using a sunfire signature 600 for the main speakers. i had to sell the sunfire because it stays on all the time and my wife was worried about our toddler always climbing on the stand.

anyhow, i need to find a amplifier for my front speakers - with the subs, they require alot of power and they are working on 4 ohm load.

i had searched all of our local second hand market and these are my options (based on my limited budget):

1. a pair of emotiva XPA-1 (4 months old - Huge !! do i need that ?)
2. a pair of Jeff Roland 201 monoblocks (2005- edition)
3. a pair of Nuforce v9se V.2
4. an AMR AM-777 (integrated with HT bypass)
5. a perreaux audiant 80i (integrated with HT bypass)
6. parasound Halo A21

thats it for now.. What do you guys think about those amps ? which would be better for my current setup ? which would be best for future upgrade to a bigger priceier set of speakers ?

due to them being second hand and the price may vary, can you sort them out from best to worst ?

is there any other option i should consider ?

thanks you guys for all your help.
