Hafler DH-100 preamplifier

摘要

Along with literacy, manners and an aversion to tattoos, another pursuit/mode of behaviour that has passed its sell-by date is hi-fi kit-building. While model airplane and model car kits still linger in much reduced form, hi-fi kit building has all but disappeared. The main reason for this is obvious: if kit-building existed primarily to save consumers money, and the cost differential between buying a made-up component or constructing your own has disappeared, then there is no justification for purchasing a kit. All that would remain - and it was a considerable attraction for some of us - would be the satisfaction of putting together the preamp or loudspeaker or power amp offered as a kit by one's self. As someone with no electronics skills whatsoever, I cherish the two or three occasions when I built my own Dynaco and Hafler kits, particularly the moment when it came to switch-on and finding thai everything worked.
