I think the tuning really more refers to an arrangement of objective filters and blocks within the operation block diagram of the FPGA and their arrangement, speed(hz, datarate), bandwidth, bits etc etc. There was a question earlier sitting on this thread this morning, and as I thought to formulate this answer I got to doing the days work, but it seems this keeps coming up so even tho I am relatively new and have not read all the threads I think I can put it into words(although Im sure somewhat inaccurately). Sure it may be possible to design the circuit in the FPGA using pure digital logic analysis and design but lets say you did that(the rules or practices to do this likely havent even been developed), still how would you know that those rules and choices were the correct ones? Is it cheating to go ahead and listen and thus take it away from the tenants of a reference design? or was that going to happen anyway and thus you might as well cheat trial and error style(also likely cause the logic design practice rules likely havent been developed) does this then make your design subjective? I dont think so because we arent talking about EQ tuning or putting this circuit in to add more bass its more just the arrangement of objective digital filters(likely designed with transparency in mind) and data paths and tweaking their "arrangement and specs" can change the sound somewhat but not so much its spectra..... more like its timing. So I would say this trial and error listening could be considered objective as it is the final test that the arrangement of objective blocks is correct.
I doubt it sounds like his sony he is just coming up with a reason not to upgrade(or realize his expensive dap is obsolete).
These are the 4 tunings.... kinda wish one was old hugo instead of roll off which I havent found the high frequency to be a problem.... but if I had Ultrasones......
Hugo (Ultimate Reference) (White)
Hugo HF+ (High Frequency roll off) (Green)
Mojo (‘Smooth’) (Orange)
Mojo HF+ (High Frequency roll off) (Red)
I was at CES also, The Hugo2 sound a step forward from Hugo + all the add on.
In addition, Hugo (Ultimate Reference) (White) Filter i like the most. Which they said it is Hugo+DAVE Filter.
Just FYI
