@lalitk -- of course, it’s been on the cards for quite some time. That’s why I said I have ’yet’ to meet a high efficiency speaker that I liked :)
But keep in mind that your Canterbury’s are in a whole different league when it comes to price and performance. I have listened to various Klipsch Heritage models (except LaScalas), Devore Orangutans, Tannoy Sterlings, and Tekton Double Impacts. They were all very very good speakers, and I have no doubt have their own fan base. Just didn't do enough for me to want to live with them long term.
I’m looking forward to hearing your setup when the time comes.
