I'm interested in picking up a pair of Grado RS-1's. Am I likely to find much price variance online for such a big ticket item, at least in the world of headphones?
Or to put it another way, do any of the audiophile retailers online offer much in the way of Thanksgiving sales?
Also, I'd be interested in any information on a headphone amp that supplies the right 32 ohm signal to the Grado's, but accepts balanced input signal on XLR's. I was looking at the Grado headphone amp which is probably the perfect match for the RS-1's, but I'm worried that going from +4 balanced XLR's from my audio interface to the consumer -10dB RCA's on the headphone amp will degrade signals somehow, or mismatch things. Sorry I'm not really up on the differences between line vs pro level, xlr balanced vs RCA unbalanced etc.
Thanks for any help.
