The Canton's are simply excellent speakers that excel at everything. I own the Ref. 7's the Ref. 9's and the Chronos. I have powered the 7's with many different amplifiers including the cheap Douk and Fosi, I have used Carver's reference, Dartzeel NHB 108 and various tube amplifiers. They seem immune from producing bad sound given that the ampls and interconnects are good. I used mainly Kimber for the Kables and various pre-amps. Yes, I'm sold. I don't just endorse them - I own them. Other speakers that I own include YG's Sonja 2.3, Q-Acoustics, Dali and some Elac's. I power the 9's with a Krell in my bedroom. They replaced B&W Silver Signatures, Chord's and Kef's. That is really how pleasing they sound. The other speakers were excellent but they didn't have the qualities of the tweeter in the Canton's which I find utterly non-fatiguing. I did try a hot cable on them one time and they did get shrill when turned up but it was obviously not the speaker but the cables as no other cables brought this out.
The transparency is you are there and the tweeter is a slice of heaven. The 7's only have a slightly larger than 6" drivers. The bass is fast and accurate under 92db.The midrange and the tweeter are the same that they use on all of their speakers including the Reference 1's. They are priced competitively and occasionally they come up on the used market. If and when some Ref. 2's or Ref. 1's become available I will pull the trigger.
