for me the music foundation belongs to the bass low bass and here the LP alternative can't even dream what the digital can do even the redbook is better than the LP compared to live music at 3-4 meters from the source.
Boy, the ability to play bass IMO/IME has always been ruled by LP. I have never seen any digital system do as well! I can't agree with this statement at all, it is so false it seems crafted to be inflammatory, but knowing you Raul, I doubt that is the case. Curious.
A straight-tracking arm solves the tracking issue you describe if its engineered correctly (I am not a fan of air bearings!). But still I would recommend spending time with an LP cutter- the tracking error of radial tonearms is almost a non-issue relative to the overall picture, as long as the radial arm is built right, and there are a few.
This all has to do with the source recording- knowing what that sounds like and then knowing what the resulting CD or LP sounds like! That is why I say the tracking distortion, so long as the arm/cartridge setup is otherwise working correctly, is not important. So I cannot agree that a digital media, at least in its many existing forms, is somehow better- they all impose an audible artifact where the analog does not.
Now understand that I listen to a lot of lathe cuts- it is from that perspective that I write this. They just don't make any noise! Yet you can cut a 50KHz carrier tone into one and modulate FM stereo into it... crazy!
I cannot over-emphasize this point, apparently. You just have to experience it.
