I have recently purchased the Sennheiser HD650 headphones. I am using them directly on with my macbook pro. I am yet to decide on the amp/dac combo. Even with the macbook pro output the volume seems be fairly decent (when used with itunes).
With VLC running FLACs i can up the volume to 200% or more and get higher outputs.
My question is, as mentioned in the title of the thread, if the 6.3 mm jack is any better than a 3.5 mm ?
esp. in the case of high impedance headphones like the Senn 650s, does it make a difference?
Or is it because of the source or other components in between which causes this perceived difference, if any.
Like for example, most of the DACs and amps, the high end ones, have a 6.3 mm out which can also be used for a headphone which only has a 3.5 mm jack (with the help of an adapter).
Do they give a 6.3 mm out because it gives better quality or because the high end headphones have 6.3 mm mostly ?
I know 3.5 mm is better than 2.5 mm.
Is it similar with the case of 6.3 and 3.5 as well ?
Experts and critics please tell me if you have noticed anything perceptible when switching between both. Also if possible, you can explain the science behind this.
