I had a listen to the 1.4s and 1.3se about 2weeks ago at the dealer in a plinius system (cd & 9200)
They were both sound very similar, typical Dynaudio "house sound". However I found the 1.3se was a bit forward and a bit edgy. The 1.4s on the other hand was more relax with the presentation, no hint of fatigue, the vocal was a lot more smooth and a fuller body.
I also brought my 1.1s to the audition and found it to closer to the 1.3se presentation. Soundstage is wide and open, but the hint of edgy was there.
I was mainly interested in vocals therefore i did not listen to lower bass materials, however from what I was hearing I would by more than happy with the bass that both speakers were producing.
For me the 1.4s wins handdown, as they suited my taste in music. For someone else they might find them a bit slow and not as neutral..... It's all about the personal taste.
happy listening.....
