Current, Amperage

@Erik_Squires 
this is really was the essance of my original question. 
So, how much ‘current’ do I need? And, is this a rating or spec that is provided? 

@lilmsmaggie 
yes, sorry, my ‘pre-amp’ is a VTL 2.5. 
I had an Mcintosh MC252 but sold it a few years ago and my stuff has been in storage. I’m now looking for a new amo as I want to setup my system again. Not sure I want to soend that much again on an amp. 

I also had seem the Focal ‘power suggestion’ of 40-250, but that is a big range. 

Bottom line, will the current/ amperage in a less expensive amp of 100-150 watts be enough to provide the right power?  Rotel, etc? 

Also, what about Class A, A/B, D - does this come into play and is it a big variable depending on your speakers, etc?

Thank you.

Thanks for the feedback; What about a Class D amp in terms of WPC. 
I realize all of this has a high number of variables built in.

Anyone else care to opine on this topic? 

Does anyone know what the 'Class' rating is for the Mcintosh MC252 ?

Thank you.

Thank you. 
I agree, and this IS the point of the discussion; What is enough [we know too little is bad, but how much overkill does one need ]?

I had a McInotsh MC252 - 250 WPC on either 2, 4 or 8 ohms, and I loved it, but do I need that again in a 12x12 room? used for $3500 for my type of setup is a lot. I don;t need the 'Wow' blue lights factor again :)

Can a Rotel 200 wpc or something else provide enough [that will be good] without having to spend more than $500-1000 used? 

Thanks; this is an interesting topic for all of us that have decent systems but maybe not more than $5-$10K into them. 

Anyone have thoughts regarding the NAD 275bee amp paired with my Chorus/ Focal 826V speakers. Seems like it has really good ’bottom power’ & great mids/ highs, as well as, plenty of power when you need it. Also a good value.

Thanks.
