HI-FI NEWBIE NEEDS HELP!


I am new to the higher end of music listening, actually I haven’t started the listening part yet. I have just purchased an Emotiva XSP-1 pre and a pair of Magnepan 1.7i’s. My listening room is 14x14 but one wall is not closed off completely and there is an additional open space connected that is 8x9. My budget has been unexpectedly diminished more by having to buy new connectors and speakers cables. I just assumed I would be able to use my old RCA connectors and my 50’ spool of speaker wire I bought from Radio Shack 25 years ago. I will pause while you laugh....Anyway, the jist of it is is that I’ve got $2500 left for an amp. I need advice on what would be good for my setup? What would last the next 25 years, as I am a poor man with expensive tastes and will probably not be able to make any further upgrades. Would something used and older be out of date technically in 10-15 years? Could I consider something new that would be adequate for that price point? Should I go mono or two channel? Thank you for your consideration and reply.

Let me put this analytically. I would like to enjoy a system that, at the highest volume I normally listen, gives the clearest music possible.
 
If you mean uber resolution and analytical sound at high volumes, then pro-audio / pro-audio leaning gear. PMC Active monitors, for example, driven by pro gear.
   Just a caution if what you are seeking is "uber resolution".  Although you might "hear" everything, you may not find this kind of system musically or emotionally satisfying over the long haul.  I've encountered systems like this that are very much on the "sterile" side and fatiguing to listen to over time.  Listen for a sound that draws you into the music and provides the "goosebump" effect, even if it's not the most highly resolving system.
   Also, an FYI that the Maggies do tend to sound better with a bit of volume.   Their sound doesn't really "bloom" at lower listening levels.  You also have to be VERY careful with speaker placement.  Inches can make a huge difference, and the listening position for them is quite narrow. My audio room has just one chair.  Something that my wife has commented on more than once...  ;-)  However, it's a great chair to be in late at night, lights down, hoppy craft brew in hand, and a favorite artist hovering in space in front of me.
