unbiased opinion of Moon monoblocs

Everything is relative. To get a meaningful answer to your question, assuming one is available, you must reveal a bit of your audiophile soul.
1) What speakers will you be using?
2) How loud will you be listening. What is important to you about the 300wt requirement. Not many amps in that range and the db potental difference between 100wt and 1000wts usually becomes academic in real listening experience, costs a lot of money, and causes you to ignore some fine sounding amps that might otherwise work for you.
3) What kind of music will you be listening to.
4) What aspect of sound presentation is important to you.

That would give folks at least a starting place. Otherwise, you will have to settle for Usblues and Goatwuss' response. 'Better' and 'Best' requests usually get worthless responses in considerable volume. :-)

You were a big help Newbee unlike G and I....thanks for the illumination.Especially never hearing them.Amazing,how did you do that?Our answers had nothing to do with his question which was second to his real reason of coming over for a hello.We were just saying hello tongue in cheek as life here is a little too lifeless lately.Would you rather have a smile or information?The one is universally accepted everywhere.The other is as relative as your post....cheers,Bob

"Thanks for the illumination" But, it was not you that I was trying to illuminate. I thought your bulb was already operating at full output. :-)

Maybe I'm humorless, or just a dim bulb, but I failed to see his 'real reason' for posting as anything but what he presented. Hell for all I know he was just trying to sell these amps, but I didn't assume that either. And, BTW, FWIW, IMHO as always, I love humor, subtle or otherwise, that doesn't come at the expense of the unaware.

Touche' my friend....
