Hello , I just read this post. I am the owner of the first ever MUSE produced by LOU.
Here are my 2 cents :
1-Since I live in Mexico, hearing them was not an option either, I mate them first with a Shindo tube Integrated AMP.
Yes they do take a long to break in.
The Shindo 12 watts was not good enough for the Muse even as efficient as they are.
2-I mate them now with a Pass Labs INT-30, 30w x 2 Class A
the sound is much much better with this SS amp that is more powerful too.
3-I have had many speakers, all less than 10K, my previous ones where Acoustic Zen Addagios, and these are much more superior.
If you have a big room,, may be you should consider a Bigger speaker or definitely a SUB. since Bass is not the strong asset of the Muse-
Regards
