Has anyone else used the pha-1 with low impedance iems, other than the Westone 4r which others have said in this thread sounds great - I think the 4r is 16 ohm. I am keen to pick one up as they are very cheap at the moment, and I would like a dac/amp that will work with iphone 5. Most of the competing products also have an impedance of 10ohm and are more expensive - except for the m8 (as low as 1ohm), but I cannot stretch the $ that far. I want to use the pha-1 with my ie80's (16ohm) and UM Merlins (12 ohm). I am far from a hifi expert so not sure of the degree of actual risk in buying this product to run these iem's. I am OK with taking a small risk here but if matching the hpa-1 with the ie80 and Merlin is definately going to result in a poor outcome please let me know.
thanks!
