!Una versione più semplice del THESIS<br />

si ottiene facendo uscire i cavi di collegamento<br />

degli altoparlanti direttamente<br />

dalla cassa attraverso il supporto<br />

e saldandoli sul circuito stampato.<br />

Tuttavia, i miglioramenti acustici<br />

sono molto modesti rispetto all'uso<br />

di morsetti e spine a banana di qualità,<br />

e anche il montaggio e il collocamento<br />

del THESIS è molto più difficile.<br />

A slightly puristic version of the<br />

THESIS is obtained if the connection<br />

cables of the speakers are directly led<br />

out of the cabinet, guided through<br />

the stand and soldered on the PCB.<br />

The sound improvements to be expected,<br />

are, however, poor compared<br />

to the use of high-quality terminals<br />

and matching banana plugs, and<br />

mounting and installing of the<br />

THESIS are rendered much more<br />

difficult.
