I've been using it for a while now and nothing really improved. It is bright that is getting not really engaging to listen to. 

  So how is Qualcomm WCD9310, with an inline class D headphone amp compared to a wolfson DAC? Are there any comparison on these two?

I've got to start saving money to try out one of those beauties

I've got the R1 2 weeks ago and I've got to say that I am not liking anything about the sound. Whenever I am using it, be it with my ipod, my htc one, or my colorfly c4, I am still yearning for it to sound better than my stock iem for htc one or the monoprice 8320. Maybe I am expecting too much...

Anybody who loves the bundled iem for htc one?

Are there any review on the bundled iem for HTC one? 

This is my first post on headfi and I've got to agree with you on the bundled iem for HTC one that it is really a good sounding iem. I've tried it on my colorfly c4 and it is the best by far iem that I've tried on it.
