Which Tonearm
is prepared or available for balanced / symmetrical operation?
We believe that, apart from Rega-tonearms and derivates, all arms have floating internal wiring, and are ready for balanced connection.

AQVOX
manufactures special balanced Phonocables - http://www.aqvox.de/cable.html
NOTICE:
AQVOX tries to build
a complete list, if you know some more details, let us know.
This helps us to complete
the list.
We believe
that, apart from Rega and derivates, all modern arms have floating
internal wiring. That means, the Signal-Ground wires are not
connected to each other or not to the turntable or tonearm or
to the chassis ground-cable. If your arm is not listed please
contact us or your dealer/manufacturer.
*only
for REGA: the tonearm internal ground wire has to be disconnected
from the signal ground. If not done, humm, radio or disturbances
-MAY- be audible in balanced input operation. All REGA arms with
separate ground-wire can be used without modification. For easy
modifications please ask your dealer or us. AQVOX offers special
Cables for this, because a Phonostage with balanced current-amplification needs for optimum sound true balanced cables with braided- or twisted conductors.
See here a illustrated instruction for modification:
http://www.aqvox.de/REGA_250_300_Tonearm-mod-humm-free-remove-signal-groundrega_mod.html
Here some cable instructions:
http://www.aqvox.de/download/AQVOX-phonocable-connection.pdf
** the Thorens TP16
tonearm needs little treatment, disconnect a cable connector under the headshell
A peace of isolation tape will isolate the connector from
the toneam metall.
