while mid-fi gear has its limits, i've not encountered mid-fi gear that couldn't be improved on immensely with mods (esp digital and preamps). speakers are tough to mod due to the overwhelming influence of the cabinet (how do you mod that?!?), and amps are influenced greatly by iron (hard to fit bigger trannys in a given chassis). but digital and preamps can get much better, and much better than high end gear at times (i've heard a modded esoteric DV50 kill an XO1-D2, and i wouldn't trade my modwright 5400 for the older P03/D03 setup straight up---however the K series is a different matter). preamps can get much better, but if its a volume pot, you'll never achieve the heights of uber gear which eschews them for ladder/single resistor-type volume controls.
its tough to get your money back out of mods though, no argument there. reminds me of everything else i've spent money on though. best bet: use a modder who's got a reputation and viable business (modwright, exemplar come to mind).
