HD650 best friend in the sub 150 price range?

[zsgooner10]

hey abi subscribers!!! Quick Question ill make it as short as i can

got a sweet deal on the 650's and just wanted to know what would pair up with this bad-boy?

I mainly listen on my laptop via fiio e10 DAC/AMP.. would hey drive them fine? OR should i invest further?

i am willing to spend upto 150 USD (more or less), 200 would be stretching but if its worth it would take it under consideration !

looking at a desktop amp or maybe even a portable..

dont know much about them cute little "mini tube amps/ hybrids" (although they do look quite tempting) but do they get the job done as in the "warm-harmonic distortion"
(was thinking about the little dot mk-iii or the hifiman hf-2a)
i mainly listen to classical and acoustics
