I just wanted to post a general comment about tip seal and fit when it comes to the 2000Js. I've learned a lot from folks reading this forum and had settled on the Sony Hybrid tips (large) for my ear canals but recently decided to try out some SpinFits to see if it could make a difference for me. Wow, was that a wrong choice. I just can't get a good seal with the SpinFits and the 2000Js just sound anemic and weak. It's back to the the Sony Hybrids and it's likely to stay there for me; the difference is like night and day! Seriously, I'd almost think I was listening to stock smart phone earbuds with the SpinFit tips on. For what it's worth I'm listening to the DSD files of the Shaft Soundtrack (Isaac Hayes) from the SACD, which to me, are reference level tracks for testing what kind of bass these things can put out when you have a great fit/seal! Sublime! To paraphrase the old saying, "they'll have to pry these Sony Hybrid tips out of my cold, dead hands"

Have a nice weekend everyone!
