While the Sony Balanced connector is an interesting addition, I would have hoped for a more professional 1/4" phone plug rather than the cell-phone earphones 3.5mm connector.
Also, the wording error of "Balance" without the D also found in the back connections is something that should have been corrected.
Strangely enough, the literature on the web page correctly describes the "Balanced" audio connector, yet the case reads "Balance".
I will forever insist that attention to ALL details is important. If the same 'lack of care' were put into resistor values or cap capacity, then the amp will be really poor. Why is it less important to write correctly?
Best regards,
Rafa.
