100+ Head-Fier
I have been listening to both the HD650 and DT880 for a couple of hours, here are my impressions:
Firstly, I think that if I did not have them for side by side comparison, I could have been completely satisfied with either. (Which I think implies that the DT880 are great value for their current retail price)
The DT880/600 have more treble and the sound is "cleaner" but also significantly leaner. The treble was a bit piercing at times but I think it calmed down now. The HD650 are pretty detailed as well, but have a very full and smooth sound which is mostly nice, but sometimes felt "muddier" in comparison. Listening to all types of music, I prefered the DT880's on some songs and the HD650's on others, so it is a tough call.
Like I wrote initially, I could live with either, but overall I think the HD650 is a better all-around headphone. Too early to judge but I think it also has a wider soundstage.
I tried the HD650 with the HRT microStreamer (that I use at work with HD598) and it sounds surprisingly good.
I am hesitant whether to keep the DT880 at home and move the HD650's to work and sell the HD598, or to just return the DT880.
Not much traction on this thread but I'll update anyway-
I tried keeping the DT880 at home with the Lehmann BCL and NuWave DSD and the HD650's at work with the HRT microStreamer... and I felt this was a compromise in both systems, so I ended up returning the DT880's.
With the current exchange rates favoring the dollar, I ordered a pair of DT990/600 (I thought the 880's were too thin so this might work better for me), and Ultrasone 880. I hope atleast one of them stay !
