Sure, and this is your opinion.
I don't think someone has much exp with higher end equipments as well as owning collection of them is going to be biased as someone only has 1 or 2 of certain brand
(Taking example of Rudi)
He said DP-X1 is clearly better than X7 and on pair or even better than QP1R pairing with Mojo. DP-X1 is the best source with the best synergy for Mojo available. Even his AK lines AK380 wouldn't be better. I take his opinion as "Reference" that means I won't deny but keep an open mind. I have owned Fiio X5 , it's good device for the price but it won't hold a candle to ZX2 not even DP-X1 . The price of current DP-X1 is unbelievable like Mojo.
