I'd be interested to hear how people are finding the Sundara's compared to HD600's.
I'm listening to the Sennheiser HD 600 atm.
I'll swap to my Sundara....
The Sundara are noticeably more open and expansive.
A smidge more detail.
A little bit splashy in the treble.
A bit less rich tonally, tbh they sound a bit thin in comparison to the Sennheiser. But I'm adjusting quite quickly.
Imaging is a little less focused.
I'm happy to have both. They do things differently.
If I chose just one right now it would probably be the Sennheiser HD 600. Which is a bit of a surprise.
But, see my new post in the Sennheiser HD 600 thread, I'm applying a fair bit of eq to the Sennheiser to get rid of treble peakiness that bothers me a lot and also boost the bass.
Also, different amps would have an impact, I'm sure.
