I'm looking at getting a portable amp for my AH-D2000s I want to spend $150 or less. I've read a little and the Tomahawk, Hornet and Pico seem to be very popular. But, I'd like to spend a little less then those cost. I'm searching around ebay now, and I found two amps that I have questions about. For $160 is the "Carat Peridot Hi-Fi USB DAC & Headphone AMP" good? USB input seems nice, and I believe I would use it, but I also found a Little Dot MK I for $110, and it seems to also be great. For the price range, is getting DAC worth it now? I don't plan on getting any new equipment for a long time, until my D2000s die. Also, if I buy an amp, is buying a iPod DLO cable worth it? I would be willing to spend around $200 (not counting shipping) if you guys say it is [Edit] By where to go I meant where else should I look/what at. I obviously forgot that as I rambled on. Also, I'm thinking I want something with a 1/4 jack, at least for the headphones as I imagine that would make a decent difference.
