Thanks for all the info guys! Unfortunately I understand only about 30% of it >_<<br />
I'm considering the Schiit Mjolnir, which has a dual 3pin XLR AND a 4-pin XLR, which is what I'm looking for; however, it's only slightly out of budget and doesn't have the 1/4" jack I'm looking for.
Ideally I would spend up to $1000 IF it has all the outputs and inputs I'm looking for (Dual 3XLR + Single 4XLR + 1/4"). I've yet to find any amp that does that.
I know this is a noob question (I'm planning to move 1/2 my headphones to balanced cables), but how does a dual 3-pin XLR input work? How do I connect that to my computer? Do I have to use a DAC with dual 3-pin XLR, or can I just use the chip on my Mac Pro Desktop (which has a good DAC chip in it anyways)?
I'm afraid we high jacked your thread...........
The one flaw with the Mighty Mo (if you want to call it a flaw) is that it only drives balanced headphones, hence, no 1/4" 'phone jack for "normal" 'phones!
Just about any computer that I can think of (not that I've seen every computer in the world! ) does not have a DAC that outputs a balanced signal.
Typically you will need a headphone amp with at least one set of plain old RCA input jacks for plain old Single ended (I.e. "Normal") output DACs.
To answer your question, the dual 3 pin XLR input is a balanced input, you would only use that with balanced source, for example, a balanced output DAC.
Bryston makes a headphone amp with these inputs:
RCA single ended (SE)
1/8" phone jack single ended (same as an iPhone headphone jack)
And these headphone outputs:
1/4" headphone jack
4 pin XLR headphone jacks
3 pin XLR headphone jacks
The bad news is a new one is $1400 USD.
Not too sure how much a used one is.
They have a 20 year warranty.
