Turntable set up- How easy is it

I decided to have a dealer, in this case also a distributor, to mount and align the cartridge in my Nottingham Spacearm. Those wires are very thin, the risk of breakin off the pins is high.
I could've done the alignment myself, but I would want something like Feickner protractor which costs more than what I paid to the dealer to have it all done.
Setting up the table itself should not be a problem with enough attention.
I am not the one who will want to change the cartidges often, probably once every three or five years.
Playing with VTF, VTA and bias can be fun though.

I wouldn't do final arm adjustment until your the cartridge had been fully burnt-in, that's at least 100 hours but possibly more. 100 hours is a kind of universal number, more or less. My Grado phones was not fully burnt-in after 100 hours but probably 90% so. The same with Purist Audio interconnects. But both kept improving after 100 hours. Cartridge is something different but still..
I would give it 200 hours. Now if you are going to adjust VTA and anti-skating for each record as some do - you got a problem of being frustrated and busy all the time.

We have better hearing and more objectivity than Peter. Just kidding. 

There is a thread here, most people agree that 30-50 hours are needed for certain. Some think 100. I am trying to save the man a lot of time and effort. Make the initial adjustments to cover the basics, then wait for 200 hours and spend a day to get it right. Not too much work. But if he wants to make it truly spectacular - align the cartridge by ear. This might take couple of weeks, so what? I was kidding. I certainly am not going to do this, though it could be interesting. In this case you would be doing individual custom alignment.

I don't have enough experience to insist on anything. However, he is one man, and there are other cartridge manufacturers. For example, Nagaoka states 30 hours, and they don't say it will be fully burnt-in after that.
Anyway, if it doesn't or almost doesn't need it, that's perfectly fine. I just never encountered a high-end device like that. It varies wildly, true.
Who would know more? Well, people don't always say everything they think. I believe, Vladimir of Lamm said that his amps would work well with any good quality power cord. And that's true. What he didn't say was that they would work even better with great quality matched cord. Lamm/Purist Audio/Kharma set-up was consistenly considered one of the best by many. Another example. My tuned Nakamichi deck exceeds factory specs and with Purist Maximus cable and Maxell Vertex tape sounds far better than guaranteed by Nakamichi in 1981. They might've tested it with the same quality cable but I doubt that they insisted on using it. So, I don't think that Peter tells the whole story.
In any case, if I hear the difference, I do hear it. It can be subtle and it can be not.
