I think what you meant to ask is, if they rival bose, sonos, or cheap earbuds, since that is your reference. And to answer your question Ken, yes, a pair of speakers someone can actually afford and own sounds better than any $200k speaker that only plays in your imagination.
To the O.P., I drove mine with an Anthem I-225. They are power hungry. Perhaps the least efficient speakers I’ve owned, and I’ve had a bunch.
I did not pair mine with a sub, nor cross them over. I was actually wondering if my pair had been over driven and were damaged but ATC said that I was just playing them too loud. I was only playing them at a low to moderate level and on certain kick drums, the midbass driver was not happy, and since ATC stated that nothing was wrong, I moved on.
Anyhow, I think your ida 8 should be fine with them. Let us know your impressions of the ATC’s once you get them. They did certain things, better, than any other speaker I’ve owned. It’s hard to put a finger on it, but it’s the inner detail, prat, and scaling of dynamics or crescendos that really took me. Its a speaker that will let you really hear the emotion and slight fluctuations in a performers voice.
I’d be curious to hear the SCM7’s crossed over at 80hz with 2 nice REL subs.
If I could find a pair of SCM 11 V.2 for around $1500 I’d personally buy them, that’s how much I like the SCM7’s. I think that white finish you got might be the best looking as well! Nice job 👍
