Its not hard to get good sound these days. If you are targeting high end, whatever that means, you probably have to be pricey and build Lamborghinis. But how many people really want or need a Lamborghini? Gotta make your money somehow.
Really sorry to hear that this has affected one off my favorites ARC to such an extent though. Should have left good enough alone IMHO. But that ain’t the way things go these days though.
Even one of my other favorites, good old blue collar OHM has raised prices considerably in recent years, at least for new stuff, but they also provide many ways to get the same quality sound for less via upgrades, trade-ins, refurbs, sales etc. Gotta look out for your customers always. That's the main thing.
