Thank you for your comments.
Possibly I did not give the AX5 enough break in time.
I bought many Ayre products and for most part I was very satisfied:
Ayre QB9,V5XE(still have it) DX5 and finally Ax5(about 24k$total).
DX5 was very good with 2 channel audio but the blu-ray picture was average.
Both qb9 and dx5 have only USB input.
@ rufi I have nothing to hide.
For now I am using DCS Debussy as a preamplifier and DAC.
