Update on my Fonolab SUT. It's only been a couple days, but I've worked my way through a few genres of music and a range from audiophile to average pressings. Without a doubt this is the single piece of gear that's had the most impact on my system. I'm sure that part of it is that the Goldring Elite can finally shine, but my speakers and my phono stage no longer seem like the bottleneck in my system. I'm sure once I upgrade those it'll be even better, but I don't feel like they are necessary upgrades to the extent that I did last week. The speakers especially are complete transformed by what the SUT is doing. I can pick out each and every instrument in every genre. Even crummy pressings suddenly sound much better. You can still hear the defects and pops, but there is no background noise that isn't a result of the pressing anymore. The low end and the high end, which I always felt were a little less than they should be are now clearly there. I feel the bass and there's no loss of clarity and detail on the high end. I didn't realize what I was missing in the mids before either. How a passive device can have this much of an effect on the quality blows my mind. I honestly don't get it, but I've never been so stunned by the sound of my system. My wife, who lovingly thinks we're all dumb for our hobby
, even came in and stood for a minute and asked if I'd changed anything because she said she could actually hear a difference and finally understood what I meant when I said vinyl sounds better. She was genuinely surprised by it. So this is a ringing endorsement for Fonolab. Heck of a Czech engineering team.
