The best turntable for making Mixtapes? Many would argue it’s irrelevent. Doesn’t everyone use CD’s? Not by a long shot. Many of the best (and weirdest) records ever made have never been converted to CD or Limewire. They’re on good old vinyl. You remember vinyl! It’s certainly not a perfect medium for storing music, but it has big advantages over digital that I won’t go into here.
Unless you plan on DJ-ing at parties and the like, a good turntable does not have to be rugged and fast. The Technics ‘wheels of steel’ have the rugged direct drive DJ market wrapped up. These are fine units but there are WAY better sounding turntables out there. Of course, if you’re going to be putting your vinyl on to a tape or converting down to CD or MP3 this talk about perfection is pretty silly. Most of the advantages of an amazing turntable are lost within one generation. But there is something to be said for starting with the best possible source and for my money, that is the Linn LP-12.

The Linn LP 12 is a bit like the Porsche 911 of turntables. It’s been around forever. It’s been updated and improved over the years, but it’s still the benchmark–the one against which others judge and compare themselves. It has many worthy challengers, but when all’s said and done, why not get the real thing? I got mine second-hand and it’s simply a great machine. It’s very musical and true and solid as a tank. This last point is important–my previous turntable was a B&O Beogram 2000 and that was very fine but didn’t survive the move to New York!

It doesn't get (or sound) much better than this.
