I have experienced the top end brightness with the Dyn 1.4s both times I've auditioned them. Associated equipment was McIntosh MA 6900 and ML Integrated which IMO, are not bright in their presentation. Digital front and was the top line Rega and can't recall the other but it was on the pricey side.
The 1.3SEs have a smoother top end plus I didn't experience the mid-range magic of the SEs with the 1.4s.
