The sound is amazing but the complexities are daunting.
Its not that bad. It only seems like there are a lot of things to learn because right now you haven't learned many of them and so they seem to be coming at you from all sides. Its really not that many though and each one of them is really very simple once you break it down.
Also while going through the learning curve it will serve you well to keep in mind what you already know: The sound is amazing!
I have been buying, and playing, and modifying, and even building turntables since 1976. In all that time I have yet to hear the one that didn't sound amazing. There was even one time a gramophone in an antique store we put a 78 on and even that was amazing!
I bring this up because too many audiophiles obsess so much on doing it perfect they miss out on a lot of opportunities to Just Do It! You could for example cut any old piece of wood up, put some holes in it, screw it to your table, and mount your arm to that. Just to hear how it sounds like that. Won't be much work (he said, having everything just sitting there in his shop all ready to go) and you will gain untold experience just doing it. And hearing it.
Then send it back. Unless you fall in love. Which you might. In which case you go looking for better wood to make it all pretty and nice. Or send it back anyway figuring the shorter one will be all pretty and nice, and probably sound pretty much the same. Which you will never know- unless you try.
