I'm sure this has been asked many times before but I searched and can not find the answer...What is the difference?

I own the original M22Ti QS4 and VP 100. Loved them.

Considering an upgrade to the M80Ti QS8 and VP 150.

What did Version 2 change?

Yup, this gets asked quite a bit.

Short answer, not much... No need to mess with a great product!

Yes, Soundman...I would not be to concerned. Part of the name change resulted in some small changes over a period of many years.

Now, upgrading from the 22's to 80's would be a huge jump. Going from Qs8's to Qs4's would also be a nice upgrade. The center channel might see some improvement if you have a huge room.

I think you may have momentarily contracted dyslexia here.

wow, all this time I thought the QS8's were better. I wonder if axiom will let me 'trade down' for the QS4's

I can help you with that. PM me.
