Okay my buddy in the dorm room accross from me, the guy who got me into DIY audio, is adding on to his list of ongoing projects, with modifications to his fideck (SP) amps along with his roomates cheap sony amps. What he is doing is bascily trippling the capacitors on the rail, going from somthing like 10 joules to about 30 jouls. he is also taking out the realitivly cheap binding posts and replaceing it with evenly spaced, nicer (for bannana plugs) binding post. I am just wondering if this will be worth the time and effort, he says he can snagg all of the caps off ebay for somthing like 20 bucks between the two fidecks he is putting somthing like 16 caps where it did have 4. Also has anyone else done any sort of mods on their recivers? and how has their experience been?
