Best speaker brands for transient response

Be careful with Borresen, they are impressive first and very fast, but they sound very digital and mechanical, they do not give a natural sound. 

Thanks for the feedback on Borresen -- I love their design but they are larger than my other options and worry they may overwhelm the room (although in reviews they are noted to sound great at low volumes).

I'll look for that sound signature when I demo them -- my KLH 3s are very fast but definitely not a digital or mechanical sound.

My choice for transient response with all the other desirable things included is a toss up between...VMPS tower II special editions...no longer made and seldom ever show up for sale used because people that buy them, keep them forever. Ribbon super tweeter, inverted cone tweeter, 5 " carbon fiber midrange and Dual 12" active drivers with a slot loaded passive radiator at the bottom of the enclosure.

And then the most amazing sound I have ever heard at any price, Ohm A - transient response and distortion extremely low at ALL frequencies. Truly an amazing loudspeaker, but ultimately flawed, limited ability to play loud without self destructing from cone over excursion and they required like 300 watts minimum to sound good and 301 watts to blow em up. I would love to have a speaker with the Ohm A sound quality but better durability and better dynamic range.

3rd on my list is the Klipschorn for all its capability, it is just not that accurate but it is exciting and engaging to listen to... and I think it has the transient response and relatively low distortion characteristics that are required.

I owned the VMPS for 20 years before a fire destroyed them...I cannot find anything so far that I like as well, let alone better. I wanna try out the Ohm F5 which is said to outperform anything Ohm has ever built. IF that is true, that might well be my endgame speaker. We are gonna find out in a few months....

@livinon2wheels have you heard other models in the Heritage line? I heard the La Scalas for a moment and they were surreal, could not spend more time with them bc some guy kept fiddling with the Mcintosh amp that was driving them. I was amazed by the holographic imaging, but didn't have the chance to test them for transients.

There are a couple of heritage line dealers in the city that I plan on visiting and will try out the Forte. The CW is too big for the space i have to work with.

Surprised to see no mention of Revel here. Percussion comes through with amazing clarity on the F206, which requites transient capability, right? And Revel has several lines superior to those (and one line below, whose F56 is not as clear sounding). To my ears, the Revel's harmonic and transient clarity is far superior to the ribbons in Emotiva and the horns in Klipsch. But then, there are a number of brands being discussed here I've never heard.
