Amp for nee LRS Maggies

Not sure, But I trust Steve. of the handful of items I've bought because of him, he's been spot on each time...

Hmm. 
4 ohms on those speakers.
What is your budget?

I would like to keep it under $1,500 as the speakers are $650.  No sense in buying mismatched items IMHO.

My 501s were about 1,000 more than my 3.6 Maggies, but they were used (going strong 9 years later!), and the Maggies were new.

Class d amps  are a great way to go if you don’t want to spend a bundle.  I am pleased with W4Sound.  Let’s not start the debate again however.  

Well for the $1500 budget you can get a pair if Vidars and run them as monoblocks. That is likely your best bang for the buck given the budget. You may be able to get them for less on the secondary market if you can find them. With the money you save get the Mike Powell Maggie instant upgrade which costs only about $79. Dig around and find another $270-$355 for MyeStands. You will be please at the difference.
