A pitch too High!

Is your tonearm still lowering toward the outside of your record? Is the curved bar that the tonearm sits on when you raise and lower it level? Might wanna check it.
Turntable setup is very basic. Take your time and you’ll figure it out. 

For the record, we use a Grado (wood body, low output) here at Atma-Sphere. I've run Grado cartridges many times off and on over the years. For test purposes when mastering LPs, I use a Grado Gold mounted to a Technics SL1200 to see if a regular common turntable can track the cut made.


The simple fact is Raul is clueless about my personal life and simply has no idea of what he was talking about. I've used more Grado cartridges than all the others I've used put together!


While it is true that the Grado site lists a rather low inductance (lower by an order of magnitude from what you would expect to see in a high output MM cartridge; I've not measured one of the high output units but I'd not be surprised if this is a typo), the simple fact is they respond quite nicely to loading. When a high output MM cartridge was all I used, I would load the Grados (as many of my friends did) at about 10KOhms with no capacitive loading at all. A few years ago I had a Transfiguration LOMC cartridge fail (one channel died) and sent if back for repairs. After a few days I was Jonesing for tunes and the only cartridge I had on hand was a Grado Green. Since the Triplanar is very adjustable and thus easy to set up, I installed the Green and took some care doing it. To my surprise it tracked beautifully. But it was a bit bright. So I loaded it at 10KOhms and the up front in your face brightness was gone- at that point its tonality was identical to the Transfiguration, which was at that time a $4500 cartridge.


IOW I speak from direct experience.

I use professional Grado DJ200i cartridges for about 15 years with standard 47k Ohms loading (or with optional 100k Ohms loading). Tracking force is about 2g. The DJ200i model is equal to the Grado Black series as far as I know, but with different styli made for professional use (with higher tracking force). In the main system my reference Grado is rare XTZ model. Those cartridges are definitely not bright.

Maybe your stylus is damaged? You can try another stylus, professional styli are compatible with your Grado too. If you want to use higher tracking force you can always buy DJ100i or DJ200i styli.

Assuming your arm or cart isn't defective, I reckon your 'guy' hasn't a clue what he's doing.  Every time he touches it, it gets worse.
Get in someone sensible to check everything over and re-set.

By the way, I auditioned the Boulder in my room for three weeks.  I found its sound rather thin and clinical.  Digital shall we say.  I didn't buy it.
