Congrats on the upgrade!
Would love to hear about the differences you witnessed by upping the power to the S3's (being a fellow S3 owner). I'm using the baby XA60.8's on my rig.
I may have missed it but, what is the size of your room?
Room is 13'w. There is 14' back to my chair which is up against the "bar" which forms a 1/2 wall into the laundry room, which is another 7' of depth.
Not sure what I can attribute to the change from 100 to 160 vs the change from .5's to .8's, but the main difference I heard immediately was the control of the speaker. The low end was the most defined I've heard in my system and there was additional low end depth I had not had before.
When I had the chance to meet Peter and hear his system, he shared his journey from 100's to 160's and it seems he had a similar experience. I wouldn't have thought that the 100's were under powered for my setup, but the improvements I have with the 160's, even in my small room, points to something..
As I listened more, the midrange was more balanced with the rest of the music presentation. I think this may be the .5's having a sweeter midrange vs the .8's. I preferred the .8's in my system here.
The other factor I heard has that the .8's were "faster" and more resolving vs the .5's, yet I still have an overall musical presentation. I have had Soulution in my system to demo and it was faster and more resolving as well, but the Soulution was more "dry" vs what I hear in the .8's.
My long term goal is Magico M3's, and I think the .8's will be a great match for them as well.
