Upgrade my 332 to 431?

I owned a 336 and upgraded to the 436 monos. They bettered the 336 in every way. I think you would be very happy. I believe the 431 will be lighter and easier on your back too!

I bought a pair of 436's a couple of months ago and they dropped my jaw when I put them in my system. I did an A/B with the 336 and the 436's were clearly more open and organic than the 336 and yet still had better bass authority. I also compared them against the 432 and the 436's are a clear improvement. The soundstage on the 436s is on the order of a football field and the warm, open midrange is goose bump inducing - very much like some of the high end tube equipment I've heard. On vocals and piano recordings I've played recently, well, let's just say I saw God.
