Hello.
For me sony is better in the refinement of coherency. Let me explain. The transition from bass to mids and from mids to highs is more natural and controlled in z1r. Very smooth and natural. On the other hand, the bass in semper bleed to low-mids and we have a "sss" sound in upper mids. Just a lit bit.
Bass in z1r is smooth and not bleed and de decay is slower and natural.
The mids tonality (perfil) is better in semper, and also the timbre is more natural. In both models we have precense of second harmonics (consonants) but in semper we have a extra of harmonics that finally add body.
Treble is other thing very complicated. Eventhough semper has very fast transition and articulation with good natural timbre, it has a loose of information in some regions. Some songs just loose tiny nuances or even loose INFORMATION in some pasages in treble region. On the other hand, z1r NEVER LOOSE NOTHING. We have a lot of extension and information. But Z1r is a lil bit slow in transitions in comparisson to semper.
Soundstage is the same in closed back version, but in open back configuration, semper is tallest, and wider. Depth is the same in both.
Amplification, is the same in both.
