Considering A SS amplifier

"There is no way to move the component rack between speakers to shorten speaker wire runs..."

"love/hate relationship with wiring"...

"other" amps are not going to resolve loss with "8 Meter" long speaker cables.

You have made some very good points.

Try a Pass Labs class A SS amplifier and unless you really mind the efficiency & heat generated, you will never ever look back.

Budget rules!  If you’re flush, Mark Levinson, Krell, PASS Labs, AR.  

Best budget , both integrated or pre and power amp separates are from AVA. 

My personal favorites, in order:  Crown, Bryston, Audio by Van Alstine,  Paradound, NAD and Rotel. Rotel is particularly nice sounding at reasonable cost.

But my advice is Crown. I bout my four hundred RMS WPC Crown power app on Amazon, in like-new condition for $299.95. Hard to beat a deal like that!  Effortless drives my low sensitivity five homemade bookshelf home theatre speakers. 

Hello,
I tried to look up the specs of these speakers. They appear to be 93db efficient. That is very efficient. I have read here at AG when you cannot use enough of your volume it is a bad thing. I believe Klipsch horns have some of the same issues. 
Speaker placement and room correction are huge. Do you have something to prevent 1st or 2nd reflection points. I saw these speakers can really fan out 60*-90* from the teeters. 
I am not sure but maybe you can bi-wire them using two different speaker cables. Maybe even some Romex from the hardware store for the bass and regular speaker cables for the highs. Be careful with silver. I see these speakers have incredible highs and silver might start to rip your ears off. Please try to get the amp close to the speakers and do longer XLR IC if you can. More power and less noise. 
Some times I see people put bases under these speakers and angle them up. Buy some shims for doors at Home Depot and see if it helps. 
I agree with everyone about the amp choices for SS but add Classe and Jeff Roland to amp to try. These speakers are really nice. They are like the JBL S4700’s. You might want to see what works well with them and you might have to call a JBL dealer and see what they recommend. 
Try to stick with copper speaker wire and IC for now until you solve this puzzle. My experience is silver is great at bigger gauges but tends to remove the realism of the sound sometimes and is very expensive. A lot of people have better results with 10 ga copper wire. I biwire with Analasys Plus 12 ga blue for the woofer and 2-16 ga purple for the highs. I know it’s wired but the way the current travels on the smaller ga wire but doubling them up sounds awesome! This is their bulk wire. I use to have the Solo Crystal oval 8 biwire but decided to sell it because it did not make that much of a difference on my system. I wish I had it now for the low end.
