atc 150 asl pro

Passive speakers start out with a huge disadvantage since amps are not optimized for the driver, crossover absorbs power and fine detail.
And any ATC speaker is good on it's own merits, just that active takes it to another level.
How do you get a $20,000 speaker on a demo? Can you ship them over to me when you're done?

IMveryHO, the ATC will outperform the Mark Lev, i.e. ultimately the sound emanating fm the spkrs SHOULD be the sound signature of the pre.
OTOH, congratulations on getting a pair of ATC on demo @ home! Care to give a quick course on how you managed that:)? Cheers

I love my ATC speakers. The passive version is hard to match with right amp. However, when you find the right combination, it is the best modern speaker I have heard.
