I searched, most threads are a bit old, so I was hoping for some updated info. I'd like to get a Cmoy...not sure I even need one, but what the heck. I will be used with my iPhone4 and yet to be determined IEM's. I saw some that were up there in price, $60+ and I am really not wanting to spend that much. There is a seller on ebay that has some priced right,[size=x-small] juice2214. Has anyone used anything from them?[/size]

most people tend to either go with a bsg cmoy or jds labs

I'm all for the CMoy from fred_fred_2004 on ebay... I'm using the bass boost model with the 2227 and it sounds the business...
 
But depending on the IEMs you buy you could be wasting your money...
 
I have the Audio-Technica CKS77 IEMs and they are incredibly powerful and bassy without an amp...
 
Depending on what IEMs you buy you could be wasting you cash...
 
Any IEM that needs an amp means you should've spend the amp cash on the IEMs and saved a lot of hassle...

Really leaning towards the HiFiMan RE262's which need amped. So according to you, instead of spending $150 on the IEM's and $30-50 on the amp, I should looking for IEM's in the $150-180 range that don't need amped? Suggestions that will fit the HiFiMan RE262 profile?
