Alright, I've heard that the passlabs A75 is simple enough and is a good design. My question, is how much do you think it would cost me to build? I found the PCBs for 9$ and 15$ for the PSU and the amps respectively. I'd build the case myself, as well as the heatsinks (I've been building CPU heatsinks for a while (overclocker ones, very LARGE and efficient, ie high quality copper ones, amp heatsinks should be a nobrainer). So I'm just asking for a ballpark figure for the electronic components. Because I'm only a poor student, and if it racks up a huge bill, then I'd have to unfortunately have to put this project on the back burner for a while (just built some expensive speakers, so I'm not swimming in cash). Thanks...
