Here Focal Sopra 3 are £16,000 and a P20 £10,500, so that’s 65% more. I assume that as @onehorsepony asked about changing his speakers, these suggestions are in addition to changing his speakers. I was recently in the market for a pair of speakers the same price as the Sopra 3 but demo’d the Diablo Evo, which is smaller and the next level up. They are very popular because they are better quality with a big sound for their size. They have a bigger sound than the Wilson Sabrina I bought. The Sopra 2 are apparently the most popular of the Sopra range.
Having had Focals ar home on demo in December I found they imaged very well with a big soundstage, and they didn’t need a regenerator as I don’t have one. My dealer doesn’t sell regenerators either. B&W and Focal are both highly regarded UK/EU brands with lots of owners, but here hardly anyone mentions using regenerators. I had one, but the advice was to use it only for source components and plug the amplifiers in the wall.
