The assumption that more money leads to better sound is often faulty.
more than one thing can be true at the same time
budget systems, well assembled, expertly set up, can sound very good, bring tremendous enjoyment, have enduring qualities
but more money, spent wisely, will yield better sound, better music, even greater enjoyment -- if properly attuned to the owners’ tastes
the above are not contradictions, they co-exist in reality... the fun (and expertise) in this hobby to put together gear that brings us musical enjoyment is to be honest about what we like, spend $ wisely up to our comfort level, find our own sweet spot
it is about the music... creating our window onto musical performances to bring us happiness
