Which goes to show that stupidity and wealth are not necessarily mutually exclusive. Anyway, I did post on Audiogon for a while, but the comments became too abusive for my taste, not to mention idiotic.
Really high quality audio was never a very common thing, I think. Also, at the high end the sound quality has not improved dramatically. I own two Quad systems, my current one with Quad 2805 speakers (plus a good subwoofer with room eq) driven bij a Quad 606-2, and my first serious system from my student days, with Quad ESLs and a Quad 33-303 amplifier. The new system is better, but to be honest not dramatically so. The biggest improvement in my audio history was the introduction of digital audio when I bought my first Philips cd player in the early eighties. The recent addition to the system of a subwoofer with dsp room eq was another big improvement, but one that only made sense after digital had replaced vinyl.
For the vast majority of the population the need for any fancy stuff has disappeared. Budget disc players are excellent and so are internet radio, or the Chromecast Audio. A few hundred dollars will buy you an excellent amplifier, and even budget speakers are much and I mean much better than they used to be. So what matters now is to incorporate that 'good enough' technology in a convenient life style system for people who are also happy to spend pretty big on their new IPhone every other year or so. Sonos got it dead right. Get their new 2x125 watt AMP, put it out of sight, stream music and radio from Spotify, Qobuz,TuneIn etc, connect it to your tv screen for great tv sound, and add a pair of decent speakers, or even superb ones like the Harbeth M30.1, and you are all set. So what is there to agonize about? For many, the answer is: nothing.
