Screen protector and cushions for my backside.
Non-slip ventilation.
I see you are using the unit as your source. More people need to realize that they can just sell off their dacs.
I said goodbye to yggy & holo-spring R2R dacs a while ago when I replace them with the Sony WM1Z. The organic sound was unparalleled.
It easily was preferable to them.
Then I graduated to the 220max, and lost a bit of holography and organics for compromise to gaining dynamics, liveliness, and power...
Then the 300max(SS) comes and totally brings back the holography and naturalness with the AKM chip!
Retaining the dynamics/power, and then also giving me a silky lush nature, and more low end weight.
I knew that the AKM chip would be good from listening to it from the AK SE200, but wow I never knew that the ibasso could make it outperform even R2R daps.
Then come the Ti, which loses the slight thicker low end lushness and weight, while slowly retaining/regaining the tonality from an early initial brightness.
I believe it needs more burn in time than the SS version, simply because looking at the audio board. The fact that different caps burn in different time frame, and one type would impede the time frame of another.
While as the SS unit has mostly same brand caps, so break in time would be more uniform and similar.
I've search the entire web for one bad impression on Ti, found none. Lucky those who own it.
Well, there is the initial brightness before burn in.
Then there is an issue that I need to verify with other owners.
The SS unit consistently sounds louder than the Ti. On the volume knob I increase the Ti knob by about a quarter inch. I am thinking it is because of the increased cap reserve on the SS unit.
You can see in pic below, the caps that I noticed are larger (circled ):
I cannot account for any other reason why the SS has a slight more output.
Need to verify with others, and also burn in the Ti unit. I believe it will take substantially longer to burn in.
