Amp/Preamp combo for Wilson Sophia 3's

I had many discussions with Pass Labs as well about there limitations. Pass Labs is very good in giving a deep and wide stage. But it still lacks the sharp and small individual focus of instruments and voices like they sound in real. But also how big they need ot be projected. So you need the right cables to creatre this. I sold my Nautilus 800S to a person with a Bryston 7B. This was a very good combo. An 800S cannot give a deep stage so in these situations an amp which can give a deep stage make no sence. You Always need to know what the properties are of the speaker you own. Only then you can look for the amps and sources which can give all these properties/ talents.

I see. Very well then. Just to let you know, my current speakers are JBL S4700s. They are rated at 6 Ohms, and are rather sensitive at 94db. Now I can use a smaller amp, but I have found they do better with high power due to the control of the 15 inch woofers. They are rated at 300 Wpc, which is what I am pushing them with with the Bryston amp. Actually since they're 6 Ohm, more like 400 Wpc. Even so, they sound a bit restrained believe it or not. Ideally, I would like to double the power to really wake these up. But power, especially high end power, costs a good amount of money. So, another 350-400 Wpc amp into 8 Ohms would be ok, I suppose. One that is more effortless than the Bryston. So let me know if Pass Labs will do the trick. I am also looking at Accuphase and McIntosh. This has nothing to do with Wilson speakers, but I believe they like power as well!

Your speakers use crossovers which are not capable of giving depth. You need a sharp focus and power ( watts and lots of ampères) to control your speakers. That isn why a Bryston is a good match with your speakers.

Why are they not capable of giving depth? How do you know this? Ok,so a good match? Thanks. Would you recommend a Class A amp or Class A/B amp?

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!!
