Damn you Head-fi,  I have already fallen into your clutches and have been seduced into reading reviews, buying wonderful sounding things and then wondering if something else is just the thing I need to have.............   I'm considering purchasing one of the 'phones in the title. I'm aware...

Just purchased a new A17 after a long time humming and hawing about which DAP to buy. Hopefully, I'm going to love it.  Currently it's sitting attached to my laptop and is telling me to "please wait".

Not really sure where to put this question, but as I recently purchased a pair of M100s (which I love), I was wondering what is the criteria for headphones being categorised as  portable" as opposed to "full-size" ?

I imagine they will survive.   I've been impressed with my M100s.

  Not that I've found. No price drop that I have seen - if anyone does spot one,  please shout.

My M100 with my printed shields took 6 days from ordering to delivery.

Yeah, I've been checking the for sale ads on here regularly.   Was thinking I was leaning towards the Sony, as the safe choice but I'm intrigued by the new iBasso DX80 which was launched today.

How quickly will someone get one and post their impressions  :)

Amazon currently have the DX90 for $368  and the X5ii for $349.  

Watagump, I see from your signature, you have the DX90.  Can I ask your thoughts on it?

But I'd still need to provide a music source, would I not ?   And I want my setup to be portable. I don't mind a bit of heft, it doesn't need to be matchbox size.

Thanks vividcard, great points well made.   Your comments about Fiio UI are perhaps tipping the scales a little. 

  No problem at all classicalman, your questions (and budget) are almost exactly the same as mine, so hopefully we will both benefit from the community's collective wisdom.   I have read great things about the A&K players, but as the cheapest one I have seen is around $500, I've pretty much...

  Just wondering this as well?
