The innate noise of carbon comp resistors, is still noise,
whatever the application. Especially pay attention to the
paragraph under the heading,
'Resistor applications':
(http://www.resistorguide.com/resistor-noise/) The, "tubey"
(warm/sugary glazed) sound of many older tube amps can be
reduced
by the subbing out of carbon comp resistors, with metal film
or wirewounds(which I've been doing for decades). ie: Read
the last few paragraphs of this
article(http://www.eetimes.com/document.asp?doc_id=1272283)
In the context of this thread; If the OP wants to add
warmth, carbon comps(in the signal path) are a valid option.
