There is certainly a lot you can play around with in a record player with the cartridge setup being the biggest.When I set up my cartridge, it’s clear that settings like impedance on the phono stage and tracking weight affect the sound.
With tracking weight: to light, and the sound gets too thin and bright. Too heavy and it goes the opposite direction, too rich, sluggish and more dull.
So when it comes to the last bit of dialling in my cartridge set up, I tend to compare the sound of my vinyl playback to my digital source, using both media media that came from the same original masters. Of course there’s also the issue that even taken from the same original master tapes, the mastering for the vinyl may be slightly different. But ultimately I can get them really close, so the vinyl playback sounds pretty neutral. And then I tend to tick the cartridge weight just a little bit heavier, erring on the side of a slightly richer sound.
As I’ve mentioned before, In comparison with digital counterparts, I can sometimes perceive the vinyl playback as conveying a bit more of a warm, organic, human quality, especially to voices.
One striking example, I remember was comparing my ripped CD playback of an Air album with the vinyl version, set them up, matched levels (not with a voltmeter, but best I could) played them at the same time and with a remote button I could switch between the vinyl playback and the CD version, and when the female voices came on the CD version Had the voices sounding more like recordings, crispy edged and artificial. On the vinyl version it sounded like they suddenly became human beings singing between the speakers. (or more in that direction.). In that particular case
“ warmer” certainly seemed a reasonable way to describe the sound of the vinyl over the digital. (before this term goes on someone’s naughty list, I have said before that, I don’t think we can say that vinyl is my default “ warm sounding.”)
Changing the tracking weight within the working range should not really change the cartridge sound if it has a linear magnetic circuit but the traditional layout sensor layout does not have a linear magnetic circuit, so changing tracking force moves the sensing element into a slightly different location within this non-consistent magnetic circuit and changes the response. Big variations can cause bad non linearities, high distortion and record damage but around the "spec" range you are just adjusting the FR.
On top of that cartridges vary a huge amoun't, the ones with a flat and even frequency response, like the Shure V15 went out of fashion when reassuringly expensive hand made boutique offerings were all the rage.
I mentioned how rich Koetsus sound. They are very rolled off as are some others.
By chance I was at a birthday party on Saturday and one of my old mates told me he had just sent his Audio Technica ART something-or-other for service and fitted his old Koetsu Urushi and was was eulogising about having forgotten how gorgeous it was...
Not surprising there is a diffenence eh!?
