Interesting thread. What do I wish I had known sooner?
1. You need power to know what’s going on. When I started using 200 watt + amps, things got easier to understand.
2. Cables and tweaks do matter, but not all the time. I remember getting some brass feet as part of a deal and putting them under a Cyrus CD player that was pretty good. Wow, what a difference. Not to mention my Gaia iii footers!
3. Speakers are important but not as much as you think. Necessary but not sufficient. I’ve changed out amps and preamps and cables but haven’t had much desire to change out my speakers. Once I got to a level that worked well I really concentrated on other things. The lesson for me here is to get some good speakers early on the journey and call it a day.
4. (Biggest revelation). It takes time. When I was working I had little time to listen and changed our way to frequently. Since I retired I listen all the time and have learned to slow down the changes and really identify well recorded reference content.
I have about $12K in my system, as follows:
31% speakers
12% cables
16% amplifiers
18% preamp
18% sources
05% tweaks
My system is strictly digital. I’m my turntable days, it would have been much mi source and tweak intense. And this is a humble mid-fi system. At a $40K level, I’d be much much more focused on speakers, I think.
