Thanks both of you. Apologising for late post on this matter bcoz I have contacted ayre as recommended to get solve the issue. Below reply is received from them....
i) Do your mac software update
ii) Change your usb cable
I have done both. But no use !! at the same time my mac is not recognise the DAC also while power gets on the DAC some error code blink and leave
''U3r''
Even power "B" port also same condition.
From 08 Nov 2017 onwards sent many e-mails to Ayre customer care and they receiving the mails but not replying. There is no word to express my worries and really do not know how to solve this issue?
Previously have used of Krell, Pass labs, Modwright,Accuphase, Mark Levinson, Dynaudio, Classie and many other products and never seen such poor customer service on my life.
Anyone knows the personal contact tel no of Charles Hansan of Ayre or any recommends to solve this problem please update and am highly appreciated for the same
expecting big hope and solution on your post/reply on this matter.
Thank you
