Have you done an A-B comparison of the heard? This is a hard question to answer...It's really personal preference...and only your ears can decide...Depends your taste... at first glance of your list, I would say the Thorens td-124... It's the most well respected table of the bunch...however, I have never heard the others. Me personally, I'm looking for detail and sonic bliss, and accuracy, some say that's not possible with a TD-124, some say yes. I would say, do an A-B test and eliminate the candidates using your ears...what sounds best to you is the winner...my humble opinion...
1. Thorens TD 160
2. Pioneer PL-L1000
3. Sony PS-X7
4. Pioneer PL-41
5. Thorens TD-124
6. Rega Planer 3
