Cost does no equal tperformance. Take a look at audiosciencereview.com (ASR). as well as Erin’s audio other (YouTube channell). They both measure performance. I sold my £3k amp and replaced with one for £1k. My partner hated my speakers (too big and ugly), and so were sold to someone who wanted them and replaced by budget options that measure very well. My music sounds better (almost entirely down to the speakers) and we had a great little holiday and it all takes up much less space.
