Basis Debut Mk v or Walker or Brinkman ?

I will echo Russ' comments about needing to listen to the Walker turntable in order to really appreciate what makes it so special. I'm clearly biased in favor of the Walker having made that decision several years ago, but with the overall level of your system today, you really ought to hear the Walker for yourself. Lloyd is very accomodating and he's just a little ways west of Philadelphia: might make a very good day trip for you to arrange a listening session with him.

Thank both of you for your input,it seems that the next logical step in my system could be the Walker black diamond.

I think, the Walker would be the next level. But I think, that their Arm makes a huge improvement, too.
I changed from Graham 2.2 to Phantom and this difference is NOT subtle. It is huge.
Good luck

I do not sell Walker, Brinkman or Basis. I do sell Grand Prix Audio.

While I like all the tables you mention, I would probably recommend in this order:

1. Brinkman - Easy to setup, excellent build quality and sonics.
2. Walker - Excellent sonics, very difficult to setup unless Lloyd does it for you. Very tweaky. If you move or paint your room, could be very frustrating. If you purchase, you get, as a bonus, Lloyd's wonderful sense of humor.

3. Basis - Not quite at the same level as the previously mentioned, but rock solid reliability.

I would be remiss to say that I feel the Grand Prix Audio rivals the best tables I have heard. It is a direct drive table that keeps, probably, the best speed and pitch of any table on the market. I feel this is the most important function of a turntable.

The good news is there are no bad decisions on your list :)

There is also the Kuzma Airline reference turntable.
