ATC active vs. passive

OP,

Your thoughts on the larger ATCs are justified. I can still recollect the boogie factor on the large ATCs. They were playing Daft Punk’s Loose Yourself to Dance. It was late evening and I was tired. But still felt like dancing! Stayed back in the room till the song finished. Go for it, if you can. You can get a powerful amp later. I believe they were using some Audionet amplifiers, if I am not mistaken. But a memorable experience.

Do your SCM 40s have tweeters that sat "ATC" engaged right in the metal flange around them?  If it doesn't, these are the older SEAS tweeters used in the SCM40 Mk1's , while the newer SCM 40 Mk2's use the ATC hand made tweeter introduced in 2017-2018 or so. Now ATC is using only their own tweeter in everything

I have the scm40 MK2 version. Still lacking to my ears compared to Triangle Magellan. I know ATC SCM50 and above have a superior tweeter just not sure how much of an upgrade it will be.

What speaker cables are you using and what power cord for your 595? Had that amp 2x and it’s pretty sensitive to power cords. Top end can can trimmed to your tastes pretty easily. 

On my SCM40 I am using Audience Front Row and a DPS 4.1 power cord. Seems to be excellent synergy between the moon 761 power amp and speakers. I have no issues with treble and think the top end is detailed and refined sounding.

I did notice a difference, for the better, when I used DH labs silver jumpers. I am running the jumpers between the teeter and woofer (using the stock plates for now to mid) and I do the AudioQuest recommended way of connecting the speaker cables across the binding posts. 

Lastly, how many hours are on your SCM40’s?

cheers
