I've found you have to leave these on for a while to get them sounding good. Not burn-in per se, but just have to be running 24x7 for some reason. I cannot explain it, but this DAC always sounds crappy at meets for some reason, and I've attributed it to this reason.
Nice find though.
I just tested this last night. Trafo was an R-core with single primaries with marked phase. A 3A fuse blew when they were installed in one orientation, but not the other. YMMV.
in an ideal world, it would be 2 crossovers. and since it never is, then this is my issue. Plus, the crossovers are too simple and cannot do things like impedance flattening, which is very important in the low end region.
hey, random question.. I've bought a bunch of ASC caps recently, and have found the ones that are made in Japan have a different sound to them (for the better). Once you get them, check out the label, and I'll post the label of the ones I have that I'd propose sound better
yeah, I second the question on DIY or no. If DIY, then how much so, low end of the scale being grawk's suggestion, high end of the scale being something that deals with heat sinks and the casework chores that go with it...
figured I'd try the insanely priced resistors (Duelund silver and carbon). I mean, when your already at ~$1,500 for 4 drivers, what's ~$60 for four resistors?
Here's my inspiration:
heh, moar amps and modding the DEQ means another year without a complete system no thanks. I'll stick with Speaker Workshop and LEAP and breadboards and massive inductors for now. That said, it would be lots of fun....
and you can mod them 10 ways to sun down if I weren't such a snob, I'd own one and wire it up to each driver in a three way (speaker) and go to town...
