Amp/Preamp combo for Wilson Sophia 3's

This has nothing to do with a match. Wenn you have speakers like JBL they often use simple crossovers. I heard a lot JBl speakers in my life. Most of them already have difficulties to get the image full loose from the speaker. Depth is a lot more difficult to achieve. I love to compare. I Always want to know what a speaker can. How the image is build and if they can give depth. Even wenn you connect a Pass Labs to most JBL speakers there will be no depth. Maximum a little. I am talking about most, beause they have also some very expensive ones. Maybe they use better crossovers in these speakers. I do not know. For JBL I would go for class AB. You need power and ampères!!

These use the best crossovers that JBL makes. Ok, thank you, I figured Class AB would be the better match.

Now back to Wilson...lol.

Wilson with Boulder is well controlled. But there is no emotion in the overwhole sound. I auditoned this many times at shows. I would not even want this sound for free. At the end audio is about music. Wenn a system cannot play the sound instruments should have, you never will enjoy this system for a longer period. You need to be thriled al the time you listen to your beloved music. It is not only sound what makes listening to music special. To create an intimate sound like in real you will go to an addictive level of hearing your music. Because you will get closer to the music. There will be a lot more emotion.

Bo1972, the JBLs are capable of very good depth. The problem is not the crossover but how the amplifier drives the speaker. Higher efficiency speakers also have a lot of back EMF, which can mess with amplifiers that employ a lot of negative feedback and also have a low output impedance. The speaker does not need a lot of power; but the power that it does get has to have some finesse.

I see. Thanks for the info!
