hey everyone : ) i listen to most of my portable devices through the Ultrasone ED8. I have both the Cowon J3 and an Ipad 2 with EQu installed. I like to tweak both players to try and create a more lively space while trying to keep the overall sound balanced. I've had the J3 over a year and the Ipad 2 about a month. First i would like to say the preset equalisers on the Ipad 2 and the I devices sound terrible to me. They seem to always have distortion and have an unpleasant sound.
Firstly with my cowon J3, i love the sound quality and the warmth of the sound. I was convinced that this was the best sound out of a portable i would ever hear. (without headphone and other modifications). The biggest positive of the BBE equaliser to me, was that it could make every headphone sound much better. At the same time, while listening through my ED8 headphones, i felt like i was losing some of the details or clarity by using the BBE equaliser. Overall i'm still really happy with the J3/
With the Ipad 2, i never thought that i would be using it much as a music listening device. But i decided to go ahead and download EQu equaliser from the app store, and after a few hours of tweaking, i could not believe what i was hearing. Very lively sound, but without sounding artificial. I do most of my listening on my Ipad 2 now, when i can.
I think the Ipad 2 with a tweaked EQu eqauliser sounds better than the J3 to me. Saying that, i can't say there is a huge difference. It's definitely just a matter of taste. However, i can safely say, this is the most happy and satisfied out of a device. In my opinion, I loved the BBE settings, however the hint of artificial sound is my only gripe with it. Truly with the EQu, i just find myself listening to music instead of trying to tweak the eq over and over again to get my perfect sound.
