Been breaking in a pair of X3 for 30 days and maybe 120hrs of actual 70-85db of volume level thru them. Borresen claims 500 hrs of break in for full performance.
I have them sitting on Townshend Siesmic Podiums which will take any speaker to another level.
They are replacing Persona 5F’s ( which replaced the original Magico S3).
These X3 need plenty of break in time. I can’t see most dealers having them played enough at levels needed for break in for proper demo. If you see these at shows( which are usually demoed by a Next Level Hi- Fi )these are new speakers with basically no break in. Next Level are great guys to deal with but really don’t do a very good job of highlighting the Borresen X3 . Always paired with the Axxess Forte amps, I think they sound much better when paired with a class AB amp.
I am running a Coda CSiB integrated V3 ( first 18 watts are class A) and the X3 are sounding magical. Huge soundstage. ( I have them set up with more conventional spacing than what Borresen does at shows) The bass while not Sub woofer like, is just right for 99 percent of music. So good and tuneful that I have put my custom swarm system for sale. Definitely fills my 27x17x10 room.
While I feel I have lost a tad transparency from the Personas, I have a much bigger, fuller stage . I was listening the other day and heard the difference in height between the Tom-Tom and floor Tom. Maybe that’s always been there and I just happened to catch it but it was pretty cool. These are getting better by the week and still doing little position tweaks. I can’t see anybody not liking this speaker with a proper room ( think you need a medium-large room) and amplification.
