Hi, I'm looking to buy a decent DAC for my DT 770 pro 80 Ohms version, for around 5K (may be a bit more). I felt like Fiio E10K would have been nice after seeing the reviews and since it also has amp. But it seems out of stock everywhere I look (except Amazon where it's priced at over 10k!). 1. If anyone can give me a link for E10k at around 5k, that'd be nice and I'll go for it 2. Any other suggestions. 3. If I just buy a decent DAC, would it be enough to drive DT 770. I've an E06, so can I pair it with just a DAC?
