I have a pair of Sony MDR-F1's (nice soundstage, okay resolution, HIGH noise floor), Sony MDR-SA5000's (okay soundstage, good resolution, HIGH noise floor, microphonic cable) and Etymotic HF3's (IEM Soudstage, good resolution, low noise floor, microphonic cable). In the past I have owned HD600's so prior to the Etymotics, I had used open cans only. I like the black background offered by the Etymotics due to their intrinsically low noise floor and am curious about the DT 48a as a replacement for the SA5000 for home listening as I want to move to a closed can. Anyone have experience with the DT 48a that might be able to shed some light?
Thank you in advance,
