You might also want to look into a nice used integrated or receiver from the 70s. Many of them were built great, cost quite a bit at the time, and may sound better than a cheaper modern integrated.
Any good cheap integrated amps?
Does anyone have recommendations for an under-$300 integrated? I'm looking for a system for my office, driving 91db monitors with a NAK MB-10 CDP and CAL Gamma DAC. Thinking about Cambridge or Musical Fidelity, probably used. Suggestions greatly appreciated and thanks in advance.
