These photo are floating around...
Rumor puts it at October release.
Hopefully I'll work out something with UM in short future. We'll see.
T3 already sounds better than D-zero, so I have higher hope for T5.
Opamp is never rollable on the T series because they are all SMD. If it is like T3, iBasso might never reveal what opamp it is too.
Nothing yet. I queried them about some of the differences between the T3D and the T5 and when it would be released and all I got as a response was that it was going to be released within 1 week (advised this on the 12th) and that it was overall better than the T3D.
So not much detail and a release date that has come and gone (twice now). Seeing as there is no mention of it on the website, while they do mention the upcoming release of the D7 Sidewinder I am no longer holding my breath.
