I received Teo GCII today.
To compare with Zenwave D4 on same condition.
I used combination of Teo GCII and Crystal Cable.
Wow it has more definition and sharper focus than combination of Zenwave D4 and Crystal Cable.
But latter has more details and little bit more refinement.
Teo GCII may improve with burn in.
Does Teo Ultra have more detail than GCII?
I am not ready to go for Kronon yet.
