I will try MP301 this few day if possible. I got some news from review on internet state 6L6 tube are best if use on headphone. True ?
No experience on tube. What tube you suggest for my headphone series.?
I think i will keep the original power cord first and only change the tube for first grade.
For DAC, oppo-105 isn't that bad. plus mac with firewire on Duet is much better then any USB cable. so Dac should be fine.
