Right now I have NS-670's and I'm looking to expand...
Looking at mainly Yamaha
I want something in the range of 6-8 Ohms
I want 3 way speakers
I want the potentiometers for mids and highs
Probably somewhere up to 150 input watts lower is no issue
I probably missed some obvious models below, but that is the basic criteria in what i am looking for, what models does the AK community think I should maybe look into? Here is what I have looked at and you guys can recommend what models you think are the best. I am open to models other than the ones below, that is just some I am possibly interested in. Thanks in advance!

I know, NS-1000's are great, but I cant spend $2000-$5000
I have looked at more NS-670's, NS-690's in the original, MkII, and MkIII NS-590 NS-890 NS-500M
NS-655 NS-200M NS-2000 and NS-600
