Vinyl turntables are making a comeback and I would like to buy one connected to my Beosound Ouverture. Which turntable to choose? A new Pro-ject or a Rega with a small RIAA préamplifier or a used Beogram (4002 or 5500), a Core and a Halo ?? (I love the Beosystem 72-22). Not the same price of course and the trouble is that Beogram in good condition are very very rare. Thanks.
