Also, you may not want "hi-fi". For example, if you had an original ARP 2600 displaying all of its sonic capabilities, you'd wind up with damaged speakers and possibly the amp as well...because the ARP 2600 had DC coupled VCAs going right to the output. And passing DC to your speakers WILL wreck them...but you'll be getting everything the 2600 has to offer sonically!
For that matter, once you've dived headlong into electronic music, you'll wind up wondering what "fidelity" is anyway. A lot of inventive work in the various aspects of the field has come out of mistakes, errors, and general screwing around...and NOT trying to achieve some pristine-fidelity result from the instruments and/or processing. The only place you should be concerned with "hi-fi" is when dealing with your DAW's A-D and D-A conversion so that whatever results you got (be that "hi-fi", "lo-fi", "no-fi", or just plain screwed up) are being recorded and reproduced properly. Beyond that, "fidelity" means zilch in a form of music where there's not exactly anything that you're trying to be faithful in reproducing, and in many cases a result that was a pristine "fidelity" result would be utterly useless.
