Quote: I dont know of any good portable amps that are <$50 off the top of my head.  My recommendation is to save up and buy a fiio e17.  As for draining your battery it shouldn't unless it runs off the battery in your iPod but most have there own internal battery they use to "amp things...

Ah well in that case go with the m50s i was going to recommend the sennheiser 598 but those being open wouldn't work for you.

I think my main issue is the tf10's not fitting properly and not being able to here them correctly skews my tast in sound signature.  Quote: Did the mods really make it sound that much different?

Are you against open back cans at all?

The Denon D-2000 are the Schiit for bass.  Right now i have mine powered by a Schiit Asgard amp.     And welcome to the forums. I would like to take this time now to apologize for your wallet. 

Bump?

Well then I guess the next question is can the westone's it give me the detail and clarity I'm looking for without sacrificing much bass? Or my looking at a different brand altogether?

I also might not have a proper fit I've always had issues with the tf10s fitting poorly. But I tend to prefer a vcurve with neutral mids

OK so... I'm looking for some new universal IEM's to workout with.  I have the UE TF10's right now and do not like the sound signature at all.  Actually I'm thinking about selling them.  I am currently using a pair of shure 215 but am looking into either the 425's or the westone 3 or 4 and would...

320kbps > mp3 / flac - iTunes - Logitech USB DAC "soon to be bifrost" - Asgard - D2000 / HD598

OK thanks for the quick response.  Would my Asgard be able to drive the HE-400? And with those they will give me the bass I'm looking for with the clarity and separation I'm use to with the hd598's

OK so i just got myself a pair of the D2000 and i was mainly looking at them for a can with more bass coming from the hd598.  And well they do have A LOT more bass but over all its more of a "fun" bass than what i was really looking for. As well as the mids are really recessed.  I have burned...

Yes the 598's don't need a lot of power but if you ever end up getting other cans that do you might need a bigger amp.  I would suggest the Schiit Asgard.  I got it hooked up to mine and love it.

I just got the Asgard for my HD 598 and it was the best purchase I've ever made. And from what I've read it's also powerful enough to drive your other headphones. Just not the balance ones.
