Recommendation for ATC SCM150 Amp/Pre

@dynamiclinearityin audio, there are no absolutes. Just preferences. No matter what ATC speakers (or any other brand) discerning audio enthusiasts end up with it’s all good 😊! Besides all that , the OP clearly is interested in amplifiers for HIS new passive ATC speakers. I doubt he started this thread to have a conversation about ATC passives vs actives. If so OP, please correct me if I’m wrong.

There's a lot of truth in what you say but there's too much 'sounds good to me' in audio which is ultimately fine for each individual but there are products that do allow suppression of belief on great recordings and there's almost universal agreement active ATCs are superior to passive ones.

I have never experienced passive ATC40s(which will vary from amplifier to amplifier) but I lived with a pair about 8 years ago for over a month and they were special.

And you're correct he asked about amps for passive ATCs but they are still on order and probably can be changed and I strongly believe active ATCs are superior and also will save money.

Also ATCs are designed to be active and passive ones are secondary since admittedly there is a real market for them.

I’ve read all the reviews about passive vs. actives and debated for a while about which one would work best for me. While it is true that actives have their advantages, I ultimately decided to go with passives so I could change amplification later on to get different signatures. It’s part of this hobby. I would have loved to get an Active if I could interchange the amps but I was told it’s not possible. I would like to have some measure of control and continue to tweak for the sound I enjoy.

Have the ATC SC-2 which is a brilliant pre-amp. Add an ATC P2 and your done, even with two P2's your are ready for less than 20k (New)
