Multiple turntables

Stringreen, One of the reasons is probable that they all
sound different.I use one TT (Kuzma S.R.) but with two tonearms. My Basis Exclusive phone-pre has two independent connections so I don't need to do the(risky) gymnastics like Halcro to (ex) change the cables. With two carts (aka tonearms) one can choose the cart suitable for one kind of music and the other for the other kind of music. To my mind this is more then luxure; it is a kind of necessity.

Regards,

For those of you with more than one tonearm connected to your phono stage, you should try disconnecting one set of cables (including the ground wire) and see if the sound is affected on your other tonearm. I did this and was surprised to find that simply having the unused tonearm's ground wire connected to the preamp affected the sound. There must be some kind of antenna effect going on. You may think this is crazy, but give it a try. You may be surprised.

I really don't understand anyone other then a DJ would need multiple tables.

Stringgreen , Now that is funny,...

Hi Selectric, You are right. While my phono-pre has actually two independant phono-pres the ground connector is common. Both cabel ground wire connected to the pre
ground have some interfirance. Not sure if this is some kind of 'antenna' effect but I hear 'the effect' clearly.
According to some when you disconnect the (phono) cable ground you get symetrical connection with RCA connectors.
I am reluctant to disconnect one of the two cabel grounds
because my rack is against the wall and I nearly got hernia
by connecting both cabels to the common ground on the pre.
I hope someone 'technical' wll explain this issue.

Regards,

I have 3 up and running. I use an Adona rack system that is expandable out to each side, so I ended up with three top shelves sitting on a common set of supports (i.e., four pairs of legs support three vertical columns side by side by side). This works fine but efforts have had to be made to further improve isolation from floor borne sources. Adona is nice quality for reasonable money. The design is thoughtful and makes engineering sense. But there is no free lunch when it comes to tt isolation.
