I like truffle oil, particularly on fries. I trust my taste buds and I trust my ears. Something that tastes really great is generally pretty apparent to me. I say "MMM, I like that." Something that sounds great to my ears elicits the same reaction.
In thinking about it, I have been eating different stuff for more than 55 years, and have only been messing around with high end audio for a couple (notwithstanding my earlier experience with the 1990’s generation of Adcom amp/preamp and Dahlquist DQM9 (Box) speakers)-- all of which drove signals from vinyl played on my Acoustic Research turntable with a Grado cartridge.
This all leads me to the idea that it takes a while to learn what you like, and takes some experimenting. Education from the old grumpy guys speeds up the process, and helps build systems from components that sound good together-- I don’t think I want truffle oil ice cream any more than I want lobster ice cream.
At the end of the day, I have had great experience with Conrad Johnson for my amps and preamps, Pass Labs (Reno Hifi) for my phonostage, Rega for listening to vinyl, ModWright Oppo 105 for CD’s, and I think Mikey was right about the EgglestonWorks Viginti speakers, so I bought a pair of those and never looked back. I would take this system over pretty much any kind of truffle oil or funky flavored ice cream or typical high-end audio system. And every male in our household (me and my 2 sons) listen to Grado headphones. What do all these brands and products have in common? Great products, great sound and well-run, friendly companies.
Happy listening.
