What is the best solid state amplifier you have ever heard?

Luxman m900u is my favorite so far and one I hope to get in 6 months. 

@dpac996 You are a lot smarter than me. I went to audition the 509x and liked it a lot. The c900+m900u were both sitting there unused and I gave into weakness and asked to switch the speaker cables onto the separates. Big mistake for my financial well being. I am buying the m900u but not sure about the c900u.

I have read online or heard back from users and dealers the following to use with the m900u:

* c900u it the best match for the m900u
* Mola Mola Makua + m900u is better than with c900u
* Linn preamp is a great match with m900u

Luxman m900u (in an all Luxman system) and Benchmark AHB2 (in an all Benchmark system). Two different sounding amps. I loved both.

I bought a second AHB2 yesterday to run in mono. I was in fact deciding between the CODA #8 mentioned above and 2 AHB2’s.
