can anyone recommend a person in LA area to pay to install a tricky Koetsu cartridge

thanks for all the information I am psyched to hear the Koetsu.

I found a guy David locally who has done lot of cart setups for a local hifi shop though not my arm or cartridge or TT.....I do have the manual for the helius arm and the only trick with the TT is that the arm has to travel through the trough smoothly not hitting the bottom or the sides.  If all goes well will get it installed next week.  I will try to have my usual guy avail telephonically (as he especially needs to remain in quarantine because of health issue) if a question arises.  Unfortunately the helius is not VTA on the fly...need loosen a set screw but in a way perhaps better because this way I am not less inclined to fuss with it once I am happy with the sound.  

IF it sounds awesome roll with new guy, otherwise be forewarned and get a revisit with Randy or Brian, both analog zen masters

Call Scott Walker audio in Anaheim. They can put you in contact with the best

Audio Element in Pasadena...owned by the son (Brian) of Brooks Berdan, who was THE analog turntable guy in the heyday of audio in the 70’s and beyond...Brooks has since passed but his wife continued the shop in Monrovia to this day...the Pasadena shop is adjacent to a wonderful old town Pasadena shopping stroll...

small world I did reach out to Audio Element but for the foreseeable future they will only do in store cartridge install.

I plan to be involved in the set up so I can understand it so that I can tweak it if necessary........
