Hear that Audiofeil?
I'm afraid that I have to agree with Audiofeil - it's a blatantly dumb & idiotic question to ask. Not going to comment on the quality of the participants as I see several names that have contributed positively in many other threads.
Basically, you cannot ask "who is the king of monos?" WITHOUT giving a context. For example, if you own very eff speakers (like horns or Audionote), you could buy the smallish Monarchy Audio SM70 monos & be in 7th heaven. No need to buy an MBL 1200W/ch beast for such type of speakers. OTOH, if you have those MBL Radialstrahlers, then, an MBL 1200W/ch mono would be the king. Merely citing a big mono for its size/grandeur has no meaning & that's why this thread is a dumb thread.....
