they get quite hot, I wouldn't want them inside anything...

My heatsink is inside the case. However, I use a metal power supply case which is meant to operate this way. See my post earlier: http://www.head-fi.org/forums/f6/mil...ml#post5374411

Well i got most things in order. I have 2 questions though. There are 2 48v cisco power supplies on ebay, one is 1.5 amp and the other is .38 amp. Which one do i get?

the last question is how to you get this to run lower ohm cans like grado and sony v6's? I dont have any phones over 80 ohms and was planning on getting a 25ohm pair of denon d2000's one day.

i just bought 2 of the 1.5 A power supplies. It never hurts to have a PSU capable of higher current. Go for the 1.5A one.

the starving student shouldnt have problems driving grados. in fact, i am using a pair of grados now, and they get more than loud enough.

where did you order from?

 

[Dr Evil Dan]

as it says on the bottom of PMillet's starving student page, these can handle everything from low impedance grados to high impedance sennheisers, to the very difficult-to-drive AKG K1000s.

oh cool didnt see that, thanks

I've driven hard to drive orthos, 600 ohm Sextetts and 125 ohm QP85 with no problem although the volume knob is pretty low. I have had a prblemwith a couple of unmodded orhtos that are pretty easy to drive. I had to turn the volume down so low that I had channel imbalance. I need to bring mine home from work to put resistors on the input. When I do that, I'll probably use a better pot too.
