Hey guys, as of late I have gained interest in the idea of vintage equipment, particularly amps and speakers. A vintage integrated that has gained my interest is the mcintosh 5100, which I believe to be there first manufactured integrated amp. It is only 45 watts a channel but still a mac and isnt cheap either. I wonder how this integrated which debuted in the late 60's competes against the amps of today. Can anyone comment, or compare its performance to other low power integrateds of today such as the naim nait5i and the audio refinement complete?
