Dartzeel CTH-8550. RCA vs Xlr

+1 on Stringreen's post. The fully differential balanced circuit design allows cancellation of noise and other spurious signal induced along the signal path, thus much lower noise floor can be achieved than single ended design.

Big enough. There are transformers on the XLR inputs so the purity is not quite as good as the RCAs.

Jtinn...only if the circuit is a poor design

Stringreen: You do not know what you are talking about.

Jtinn...enlighten me....
