ADC Improved Series of Phono Cartridges 

I have several vintage cartridges. Some never even used. I find your videos interesting and I appreciate the time you put into changing these devices in and out. It must take quite awhile.

I thought they all sounded great. Difficult to pick the best but I liked 3, 4, and then 2 in that order.

I have never tried to hide that ADC is my favorite brand when it comes to cartridges. All brands have their own unique sound. Shure, Audio technica, Ortofon have a distinctive sound that characterizes the brand. Listened very briefly and the QLM probably has the most dynamics, did it feel like it also had the highest output? The downside was that it also gave off the most background noise. Probably thought the ZLM sounded very good. Otherwise, the XLM has sounded very good in my HIFI system.

The basic model plays the best here. I suppose that one is in the best shape of them. I have this one particular cartridge in NOS shape.

Could you describe your audio chain used to make these videos? Thanks!

You've got a bouncy floor haven't you there's a certain part on your floor where you're walking. I've got the solution for that if you're interested and that doesn't mean fiddling with your floor all putting up a shelf what is probably a good idea but you don't need it with this. If you're interested I'll talk about it, are you a little bit handy with your hands?
