So, I took the plunge and my Stirlings were built in 10/21. The expressly claim to have been "designed, engineered and manufactured in the United Kingdom." I made that a specific part of my request. That said, I'm a little paranoid over that. Before buying them, I took my Leben CS600 and cabling to a friends with the same speakers built in 2018 and it sounded pretty glorious!
Mine have maybe 75 hours on them and are still squawking away even with the treble energy dialed as far down as they can get. Also, wiring them to the LF and jumped to the HF helped a good bit. The distortion is definitely bie present on everything mildly improved, but disappoint on most and verging on unlistenable with many. That also lends to them not feeling well integrated across the spectrum with the midrange getting shortshrift.
Can anyone (@veerossi ) offer experience on approximate time to get broken in and how far behind the nagging tweeter might be from the bigger diaphragm? And whether my experience is similar to theirs?
Once the ice and snow's cleared a bit, I could take my Stirling to my friend's digs to compare and contrast, too, I suppose....
