100+ Head-Fier
A lot of questions x) well i did a write up of my impressions when i bought the deltas (link). I did my best describing the sound. On that same thread you'll find some graphs of the delta too (link), when @Brooko measured them. They helped me a lot.
Since there are too many filters, it's difficult to find a specific IEM of mine that match these (the filters really change it a lot), specially because the only hybrid I have now is the xiaomi hybrid and it's completely different since the xiaomi had a really laid back treble. I had the DN1000 but it was a long time ago and i remember that i complained a lot about sibilance, it doesn't happen with the deltas.
About the crossovers, Bob said this:
This is for the master 6 of course.
The master 4 is on pre-order now, the only one who can probably help you is either Bob or one of the headfiers who helped tuning it.
I hope i helped a little
EDIT: Oh i almost forgot, this seems important too, since you're checking both delta and master 4. In a question that mentioned how were the master 4 compared to the deltas, here's the answer:
I read your review and asked you some questions about it in the same thread! Haha. Didn't realize it was the same person who responded to my question in that thread. I hope I'm not annoying you so much. There really aren't that many DeltaV2 reviews on the internet. I'm curious but at the same time very apprehensive because of my past experience with hybrids.
Thank you for the link to Brooko's impressions. I'll probably wait some more for detailed reviews since there's like thirty days until the preorder discount ends.
The discussion on crossovers was also very useful too, although I can't really understand what he's saying or how it works in technical terms. But hey as long as it sounds good right!
