Most of us construct our systems over decades as we cannot afford to just go out and spend $100K or more on a system when we are 20. So, as we buy the best we can afford we learn about how to audition, how to evaluate… the terminology, detail, slam, tonal balance… we do so, listening to the kind of music we like at the time. I constantly explored new music over time…. Added a new genera each decade. So, my current interests influenced my choice of test records… which influenced my system choices. So, while the reproduction of electronic music got better on my system in the 90’s all others suffered.
To shorten, a little over ten years ago I started going to the symphony every week… Acoustical… and the direction of my system upgrades completely changed. I dropped planar speakers, switched to Sonus Faber and started upgrading to Audio Research tube gear… each step made all music sound better… not just one kind. I now own the best system I have ever heard… it is far more musical (see my ID)… I listen to it three times more than I used to… and all musical genre sound incredible.
