As compare with 5 & 1,the 5 has all the vitus of 1 but a little colored which made the sound bolder / heavier than the Ref 1,the image is too large for me, the top end is not as detail as Ref 1,one thing it truly beat the Ref 1 is the noise floor,others the Ref 1's sound extremely balanced to me.
The 5 is better performance in classical music than the 1,my music do not have classical / symphony preference.
