Charge for TT setup?

If this is being done in the store that's outrageous. Now if they have to come out to your house then that's fair.

In the late 1980's, I bought a Sumiko Bluepoint from Overture Audio in Ann Arbor, MI. The cartridge cost maybe $250 and they mounted it for free as was typical at that time. They spent about 2 hour doing it because my they had to have alignment templates faxed from Magnapan for the discontinued Unitrac arm I was using at that time.

Not surprising, with that level of service, that brick and motor store is still in business.

If your buying a $6000 turntable cartridge setup should be included. Even the online retailers will set up the turntable for you prior to shipping.

Now if they have to come out to your house, I think that's a different story. I once paid $100 for someone to come out my house to repair a broken phono lead and he also setup the cartridge. At the time, I had a VPI TNT which is not a turntable you just put in your car and carry into the dealer.
