I received my HA-2 today.  Before I purchased it, I emailed Oppo and they said it would be compatible with my iPod Classic 160 GB firmware 2.0.4 and I could bypass the DAC in the iPod using the USB connection.  wood1030 also confirmed that his iPod with that same firmware worked in an earlier...

The Oppo source said you could run it through the USB and the HA-2 DAC.  I'm looking for someone who has done this and can explain the improvement.  I think some earlier posts in this thread said they had achieved compatibility with the iPod and the HA-2.

I emailed Oppo about HA-2 compatibility with iPod Classic 160 gb, and they said it would be compatible if it has iOS 2.0.3 or 2.0.4 software.  Has anyone with these versions tried the HA-2 yet and, if so, do you think that the HA-2 DAC significantly improves the sound quality?

As a former classical trumpet player, I found the sound of the E4 to be unnatural and harsh and shifted too much toward the treble end of the spectrum. Very fatiguing. I much prefer the super.fi 5 pro.

1. It's less than $40 for two days, since you would get a partial refund from the later sale of one of the IEMs. 2. I don't want to buy both of them and send one back, because I'm not sure I will be happy with either of them compared to what I have. I may reject both. 3. If the reward for...

Triple.fi 10 pro vs. Shure E500: A Timeshare Proposal The problem: I want to personally audition the triple.fi 10 pro vs. the E500, because I often disagree with other reviewers’ sound preferences, and want to hear them myself. I personally prefer the sound signature of the super.fi 5 pro...
