[size=small] Could more experienced DIY'ers give me some sense of how difficult it would be to use a DACT step-attenuator as a volume control (passive pre-amp)?
The thought is to use an iBook as a cd sound source from the headphone out port/jack. It's an bedroom/computer workstation system and I'd like to keep cost low. In fact, if someone told me it would be no problem, I'd run to iBook's audio out right into Antique Sound Lab's Wave and control volume from the virtual cd-player on the MacOS desktop.
On the other hand,
DACT's Allan Isaksen suggests I could wire the step-attenuator into monoblocks or build a separate pre-amp.
Embarrassed to ask, is the supposition that I know enough about circuitry to design a pre-amp? I don't. Do people think I'd be better off with Dr. Bottlehead's foreplay?
Now I'm really embarrassed, but how does someone find a chasis to passive pre-amp?
I'll appreciate any pointers and advice.
