Hi, I'm wondering if I should go for this... I don't own a dedicated headphone amp or dac yet, but I do have a spare Yamaha RX-V573 AV receiver just lying around. Keeping in mind that I already have this, would this extra $150 be justified? Will it be that much better than the receiver's output?
My receiver has this to say:
Headphone Jack Output Impedance:
1kHz, 50mV, 8 Ohm ......... 100mV / 470 Ohm
And I've bought the Sennheiser HD6XX...
