Headphone amp recommendation?

[Yossarian22]

I have a pair of Beyerdyamics DT-150s I intend to resurrect with new drivers (they're dead).
I was wondering what headphone amp would suit these. I'm looking at a price range $100 or less.

I did a search and couldn't find anything on the topic, so here goes.
Cheers.

These are pretty hard to drive and I normally wont rec such pricey amp, but you might just have to get something substantial like FiiO E9
here is a good read:

I am really happy with my Fiio E9 as well. It does an amazing job driving my Sennheiser HD600 which are notoriously difficult to drive.

Paired with e7 dac you have an amazing setup for around $200 (plus headphones).

While I don't have one myself, the e9 does seem very popular and a good value at the price. As a benefit, you can even pick them up on amazon now. I think they're around $115 or so, which is a little above your stated budget, but I'm sure it would be worth it. Check out the huge threads at head-fi if you're at all nervous about the purchase.

Not necroing, I tend to post in this forum, life gets in the way -- I forget all about it and revisit it.

I pulled the trigger on the E9 but I was wondering a slightly different question:

I have the option of buying different impedance drivers for my DT150s. I think even DT100 drivers will fit the cans on my DT150s. How does impedance/ohmage play into the sound, quality, etc?

Think mine are 250 ohm (never really measured or paid any attention, got them from Sweetwater)
