Review ATC SCM 40 A floorstanders.....finally

I thought I knew.  I thought I knew all about imaging, dynamics, resolution, PRaT, all the audiophile buzz words allowing one into the coded audiophile secret society pontifications.  I got schooled.  It’s called ACTIVE.  Everthing I’ve been yearning for has been solved with my new ATCs.  They just do musical reproduction with immediacy.  The attack is instantanious.  Bad recording, bad reproduction.  Great recording, great reproduction.  Period.  Fin.  Ende.

I’ve progressed through some fairly serious talent.  Great equipment I’ve enjoyed over the decades: always the journey, never having arrived at the ultimate destination.  I do not know why it took so long to depart the traditional souce, preamp, monoblocks, cabling and transducers formula.  I hope this encourages others to at least consider leaving the world of so many pieces and cabling.

System:  Naim UnitiServe with unknown serious external PSU, Nordost Valhalla II digital cable, Mojo Audio Mystique V3 DAC, Manley Neo Classic preamp with Takatsuki 300B tubes.  Decware ICs, Patrick Cullum Crossover II PCs, Furman IT Reference 15i power conditioner.  All components sit on Quadraspire Reference X stand.  Wireworld Silver Elipse 8 RCA to XLR interconnects from Manley 300B to ATCs.  Isoacoustics Gaia II footers.  I’m really there for now.  Tchau

Reviving this thread. I’ve been living with the 40As for a few weeks now. Straight out the box they sounded fantastic. Coherent, natural, revealing yet sweet. 
Now that I got 100 hours on them, I am starting to hear some excessive brightness and edginess in the tweeter that I don’t think was there to begin with. Now, I don’t usually give much for the concept of burn-in, so I was not expecting any type of change to happen (I am usually more in brain-burn-in camp). If it is indeed a change and not just ear-fatigue, then it is not for the better. But then one could hope that this is just a phase and that the tweeter will settle with further burn-in. 
I am also not scared of using a bit of broad Q EQ, if it means I can return to the original sound I had. 
Comments and experiences would be much appreciated.

How much toe in do you have ?
If a lot, try to lessen the toe in.

Hi,
tweeters do not need run in time, so something in the amp/cross section is entering to another phase. They are very nice speakers and real good value for money, i have heard the passive version.
