German "plug and play" turntable

Find a turntable that has a tonearm that allows you to raise and lower its height. That way you are not stuck with one particular cartridge

The nano is a very basic phono. It works well in a budget TT set-up. It is better than you'd expect for the price -- but no better than that.
So with the Clearaudio MC, I expect the nano will be the limiting factor.

The Basic+ is a full scale phono -- not exotic mind you, but quite a good performer. You can use it with upmarket analogue systems.

In other words:
If you can afford the extra 400 euro, go for the Basic+. If not, you'll get good music out of the Nano, so any way you go, you win!
BTW, I listened to the MC package and liked it a lot (no, the phono used was exotic).

Excellent choice. The tone arm hight is adjustable it's simply not user adjustable.
