That's a fair point. I've been using an iPad recently to steam internet radio, as vTuner was unreliable too. If you really like the sound and can use other means access the features you want then that's a working solution.
But really these bugs should be fixed over the time, and in this case 2+ years is not good enough. I have an Oppo BDP too and the difference between Oppo and Pioneer couldn't possibly be more stark in relation to: development, customer service, accessibility and striving to make their product the best it can possibly be.
As for Sound quality, I liked the LX88 less than my 56! Sounded less spacious and more 'digital' to me. Also Dolby PLIIx surround modes have been removed. 'Replaced' by "Dolby Surround", from what I can tell this is optimised for movies, I use PLIIx Music heaps and would really miss that.
