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

@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

They replaced a Levinson 333, and in my system they are about as good as it gets for me.My speakers are Shahinian Hawks, I believe 89db and they drive them with ease (4 ohms as I recall but don't quote me), ARC pre, PS DAC/Transport, Magnum Dynalab 809 Internet Tuner and PS P12. Minor tweaks to power cords and thats it. Blows away the Levinson, again, in my system

GamuT M250i Monoblock.

Bedini 25/25 is still the best I’ve heard in any of my system variations over the years. Still have mine purchased new. I have a Bedini 100/100 amp as well. Not quite as good, but close for when I need more power. Many other amps and components have come and gone but I won’t let the Bedini amps go.
