I've had the tenores for a few days now. And even after burn in and letting my ears adapt to the tenores sound, I don't think the tenores can hold a candle to the Answers in any way. Bass decay on the tenores is extended and excessive, compared to that which is quite nicely tuned on the DITAs. The Answers also have more detail, a sharper/crisper sound, and sound much more refined. There is less bass on the Answers, but it's a better quality of bass.
Overall, I'm still loving the Answers. It's perhaps the first IEM that's not made me crave for something more - or at least not yet!
About the source, I'm currently using my iPhone 5 > Flacplayer and it sounds pretty incredible. :)
Recently tried a friends tenores and I have to agree a little, I feel the tenores scale a lot less with high end gear as compared to the DITAs, but nonetheless I'm now sorely tempted to get a pair of tenores myself :D
But after getting the DITAs, I find myself craving a higher quality source, I've finally tried the AK120 and 240, I and think I may just have to get myself an AK120.
Anyone running the DITAs out of a very high quality source? Thoughts?
