thanks @james663 @mikhailark and @steve59 for your thoughts.
I have the opportunity to pick up a second hand pair of the 328s at a pretty good price, and am currently running the 228s paired with a big rel. Knowing the tweeter is different on the 328s and that the bass drivers are different has me a bit intrigued. I might just go for it and then I'd be able to compare these side by side in my home.
