New Head-Fier
Hmm, warm sound signature - bass is more prominent, highs are more subdued. V shape, consumer tuned. I've heard the 25s referenced a few ways, but never warm. The Momentums / HD1 are the very definition of "warm". Which frequencies and instruments are you hearing better separation from with the Momentums? It's a subdued sound vs an aggressive sound. Were you feeding the 25s proper power? Speaking of which, what are your power requirements from a portable dap?
I listen to mainly rock and blues. So the main instruments being bass, guitar and drums.
I started off listening to black rebel motorcycle whole music is very complex grungy and layered, I just found the hd25s were swamped, there were 4 clear layers of guitars going on and I couldn't pick them out. One thing I found on dire Straits romeo and juliet, they coped really well and it really was 50/50, so I tried buddy guy - done got old and again they were great much more intimate.
Back with BRMC again and it was all muddled single mass in the centre of my head, whereas the momentum were wider than my head and more space between everything.
Maybe it's amplification cos the 25s are quite ohmy.
Everything played thru my Sony a15. Until I got the cyrus amp I spent the last 20 years without a headphone socket. Even now I only have 3.5mm Jack's and that's why ALL my headphones are 'portable'. I don't listen via headphones at home, unless sat at my computerand then that's cos I use the unlike mic on Skype for work.
