Without owning the uber, I don't, of course, know what I am missing, but even without it, the sound is better than anything I have previously owned or heard. IMO, it is the best audio money I have ever spent.
My suggestion to you is to get the Ref.1 without considering the uber for the moment. It'll give you the most obvious difference for the money you put behind it.
My configurations:
For pocket excellence: Tera-Player > Ref.1
For bedside excellence: iBasso DX100 optical out > DAC/Amp One > Ref.1
I am a happy camper!![]()
It's not actually boosted, but rather all DAPs lower the volume across the entire spectrum when EQ is switched on even with the bar at neutral +/- 0 db. The reason EQ is made to behave this way is to prevent over boosting beyond a certain cap and risk damaging the internal circuitry according to someone who posted on the iBasso thread. For example, I have experienced the same lowering of volume on DX90, FiiO X5 and AK120 when the EQ is enabled with the bar at neutral.
In the case of AK240, the max increase is +5 db. I have tested the exact amount lowered by enabling the EQ is around -2.5 db. So basically you just need to push the bar up to +2.5 db across the entire frequency spectrum to get back to the original sound volume with EQ off. You can try it for yourself by creating a new EQ preset with +2.5 db to all parts of the spectrum and then keep switching EQ on/off to check the volume change.
How is the ref 1 with edm? Love a good deep bass and kick with details aplenty
