I have an iPod classic with ALO national AMP.
Just wondering is HD 650 can be drived properly(like 75%?) with my source.
Personally, I think the iPod will severely limit the 650s compared to what it's capable of.
I have both, and a Naim DAC-V1 and the Naim easily beats the iPod with my portable amp (Just Audio AHA-120) driving the 650s.
