Very good comparison. Both are great headphones. I prefer the hd650, though. The sound is signature is fuller, darker.

Impressions reviewed. Actually too much bass, bloated, boomy. I have to get this phone modded, can't stand it.

Just awesome! Congratulations, David! You've posted the best headphone review ever, extremely detailed and accurate. Thanks for this great job!

I have the old NFB-12 unit and I have noticed an improve in sound after some burn in. I wish I could try different DAC filters and sound signatures. What's the availability for the company to implement a small module that could attach inside the unit that would allow us to choose filters, by...

  Yeah! I covered the holes with a very thin sheet of felt. As I look at it  against the light it appears semi opaque as it used to be before had been popped. I left 4 holes in one and 3 in the other. The bass is a little fuller now and still punchy. I got my Grado in tune. Thanks for the...

Thanks a lot guys, I'll cover the holes gluing a with a thin felt on them, as a semi-permeable membrane. I think of letting two to four holes uncovered. I'll also stick Dynamat on the the back of the driver. I accept suggestions about the number of the holes I should leave regarding the use of...

Hi friends. I always wanted to add more bass to my SR 225i cans. Last night I opened up  those and popped the ten venting holes of each. I was too agressive and should have done only to four of those. Now the sound is too bassy, muddy  with loss of details. Is it what is called "canny"...

It really sounds great with my portable udac-2, specially  when connected to my tube amp. Even though it's 25 Ohms I agree it requires an amp to drive. It doesn't sound veiled though. It's accurate and detailed on highs, not so much as my Beyerdynamics DT 880/600. Mids sounds good. Bass is...

Hi, jushtanguns   Now I'm going to rebuild my Bravo and I'll post the pictures as soon as I have it finished.  Thanks a lot so far.

Thanks for the tip. By the way, what are those bias cap specs soldered underneath the board?  

Hi, jushtanguns   Yes, the V1 has the trimmer pots for setting bias, but I'll replace those for better quality ones. The bias caps are those soldered across the bias trim pot.  I'm also curious about the power caps, why 2x Nichcon FW 4700uF 35V instead of only one? Thanks for your...

Hello, I'm new to this forum. I really have apreciated this thread once I got a Bravo V1 deluxe and I'm interested in having it modded. I have little experience in soldering but I'll start doing it so. Happy new year for everyone in this thread and congratulations for your posts.

Sorry for too many questions.
