Tidal vs ATC

roxy54 is likely referring to the ATC SCM 19A at 7K which is the smaller brother to my ATC SCM 40A.  As I've stated here several times, I'm mystified that more do not seriously consider active speakers.  

The cost argument is rendered moot when amplification and speaker cables are eliminated.

The immediacy, dynamics, timbre and slam are shockingly good.  Hope your results are satisfying.

Bought my end-game speakers nearly two years ago.
A huge step up from my Quad 11L.

ATC SCM-19.
Was at the limit of what I was permitted to buy.
And couldn't be more impressed.

No knowledge of Tidal, but those ATC engineers are onto something!

The Tidal speakers do have an amazing finish, and I'm sure from what I have read that they sound very good too, but I haven't heard them, The SCM 150 I have heard, and for a good long audition at a dealer in Connecticut. I think that they are two different animals, from what I have read about the Tidals. They are both supposed to be accurate and transparent, but I don't think that the Tidals will be able to match the dynamics of the ATCs.
This past summer, I went to the Scottsdale Speakerfest with a friend, and we both agreed that a smaller ATC floorstander was the star of the show. I can't recall the model number, but I think that it was around 7k.   

There's no way to make a good decision without audition, preferably at your place, with your gear.  

There's absolutely no way it would be safe to travel anywhere to audition speakers; not until this pandemic is over, which could be months...

If 300s are realistically in your budget....you should surely be considering the active versions.  

I'm not sure if this whole post is serious or not!

There are many ways to go for a man attracted to an amazing finish. If you want music though you should probably just order a pair from Tekton.

I should add the future listening space will be 20x30 feet, like having subs for low end duties below 40 hz (big PSA or JTR subs).
I listen to acoustic, jazz, classical, celtic, techno mainly. I value a detailed sound with powerful bass and great imaging/holography.
