Aegir upgrade to Pass...maybe

crites are ultra efficient horn loaded speakers - you do not mention your musical tastes

20 wpc aegir should be plenty, unless you listen at spectacularly loud volumes or have a huge room

i think going for more powerful ss amps is barking up the wrong tree - but maybe you are a headbanger hard rock electronica kinda listener

if it were me running those speakers i would be looking at the sweeter even purer more realistic sound of single ended tubes

Have you heard Luxman and Ayre as counter points?

I’d recommend giving Valvet amps a good look as well.  

I am hoping to keep this purchase at about $4000 or less.

I listen to all kinds of music.  I do turn up the electronic music.  Otherwise I listen to music at what I believe is the volume you would hear if the person or band was playing in front of you. 

I guess my main driver for change would would be that the Pass Labs, etc would just have better build quality and sound.  My Aegir is no slouch with great cost to performance and a 5 yr warranty. 

Back in the day, there was a Luxman dealer about 2 miles from here for example.  Now we have one dealer. 

I don't really want to mess with tubes unless I end up with 2 amps to swap around for fun. 

I think Luxman would be a top choice but am not familiar with their model numbers.  A Luxman purchase would have to be used I think and would only need a power amp.  I would buy the 900U in a heartbeat if I had the cash.

Valvet is on the home page here and I read about it briefly.  Interesting.

Pass Labs just seems to be a really reliable brand with several dealers. 

Sugden sounds like a great brand but I could only find one dealer in the US??
Thank you for suggestions folks.
