I asked this in another site while waiting for my account here to be authorized. So far, the other site hasn't been very helpful, but I'm hoping someone here can answer my questions.
Bascially, I'm surprising my father with an HD600 (or maybe a HD650). I was originally thinking that he could simply plug them into his existing pre-amp (using RCA to mini-jack adapter), but a co-worker cautioned that it could damage the headphones.
Since I'm not very familiar with the details of impedance matching and so-on, I was hoping someone here could give me a hand.
The pre-amp is a Mark Levinson ML-10A.
Specs:
Power Consumption: 20W
Line
Gain: 17dB (High), 7dB (Low)
Max Output: 6V
Input Impedance: 15k Ohms
Recommended Load: 10k Ohms or greater
This last line caught my attention. Does this mean that whatever I plug into the Line output should have an impedance of 10k Ohms +? What happens if it's lower, such as with the HD600 (300 Ohms)?
I did some searching and found these interesting items:
http://www.divertech.com/uhcsignature.html
http://www.divertech.com/aqreferencetools.html
Would using one of these be a good idea?
Finally, would a dedicated headphone amp instead make that much of a difference? If I got one for my father, it would be in the $500 range.
TIA
