Have I stumbled on my problem? New-to-me 2021 iV L&K Estate here. I'm finding that the melodic sounds and voices aren't coming through, everything is mushed together. Just tried to balance using a pink noise and a spectrum app on my phone, and then again with a few songs - and in order to get anything like the right curves, everything is becoming dull. The richness and "pop" of the sound is just gone. And I noticed that no matter what I do, I cannot get the 30hz sounds to come up at all - seems that in bumping the bass, I'm losing fidelity everywhere else. Is that the problem others are having? Am I explaining this right? I have no idea what I'm talking about, I've just spent an hour talking to Chatgpt as this isn't something I've ever played with - its only because I was so disappointed with the Caton system that I specifically wanted the L&K model for. Will flipping this plug let me turn the bass down, and in-so-doing, let me bring everything else back to life? I can't PM OP, but I'll try to tag here @spacelord as it seems you haven't posted for a few weeks and I don't want to wait for better sounds, as I'm about to go on a very long road trip! Sorry!!!
