I already said this on the Qudelix forum. For me, its worth it if you are going to use it with multichannel audio (games, series, movies etc) or you need more power.I'm thinking of getting one of these, but I'm still going back and forth between spending the $300 in one of these or just $110 to have another Qudelix 5K, which is the best sound quality I've heard in my life, by far, so much that I can't imagine anything with a better sound quality. Of course when you ask the company, they tell you it's obviously worth the $190 difference, but I wanted to check with people here before making a decision. Do you actually notice better sound quality in the T71 compared to the 5K?
And the other thing is that the T71 can only be ordered from them, and they say that the buyer may have to pay customs fees. So for people in the US, was this the case, and if it was, how much did you have to pay in customs fees?
If you are only planning to use it with regular stereo music and the 5k gives you enough power, I don't think that the T71 is would be an improvement per se.
About fees. I can't help you with that, as Im not familiar with US fees.
