Last August I acquired a Schiit Modi/Magni combo and a Focal Spirit Professional (FSP) headphones. The last months were spent comparing the FSP to my heavily modded D2000 and making minor tweaks to the latter. My conclusion is that I like the listening experience with the Denon headphones...

I'd like to point to the relevant discussion that is going on in the Fostex TH-900 thread, about activated carbon and other modding materials: http://www.head-fi.org/t/595683/fostex-th900-impressions-discussion-thread/7815#post_10851249   Personally, changing the original foam in the Denon...

I believe I should add to this, too, as I have also consulted with zolkis about modding the earpads. Although I my case I worked on a heavily modded Denon D2000 (see http://www.head-fi.org/t/350721/denon-d2000-d5000-md2000-md5000-appreciation-thread/3495#post_10348740). The activated carbon pad...

  My only success in taming the treble, especially sibilance in human voices, was by gluing felt discs in the drivers' protection grills, as described here (I'm currently using two discs on each side)...

  I'd be very interested in knowing your opinions after you do this. I've done something similar with my markl modded Denon D2000 with D5000 woodcups, although experimenting little with different materials...

Inspired by the recent release of the Alpha Dogs "obedience kit" (http://www.head-fi.org/t/676095/mrspeakers-alpha-dog-revealed-the-worlds-first-production-3d-printed-headphones/5880#post_10291892), I experimented with gluing felt discs on the protection grills of the D2000 drivers. This is the...

Below are some photographs that document my experience of modding the D2000, previously detailed in these posts: http://www.head-fi.org/t/350721/denon-d2000-d5000-md2000-md5000-appreciation-thread/3105#post_10063200...

  Thanks for the very detailed impressions, mangler. I'm actually thinking of purchasing the Vali + Modi combo for my modded Denon D2000 (with D5000 cups). The Denon is probably not as refined as the TH-600, but they might respond similarly to the Vali.

  mangler, would you please tell us more about influences of the Vali might on treble and bass? Some describe TH600's treble as slightly harsh. Does the Vali improve on that? And bass on the Vali is commonly said to be not as textured as in other amps. Do experience that as well, at least when...

  Dear prsut, could you please say something about the (possibly high) noise floor when pairing the Vali with the Denon headphones? There were very few comments about this in the thread, some positive and others negative...   Thanks!

Is anyone able to comment more on actual listening experiences of the Vali with the Denon D2000/5000/7000 or Fostex TH-600/900 headphones? I know that because of technical specifications there might be some issues with noise floor. On the other hand, there were a couple of positive impressions...

  I'm thinking of ordering the Vali from Brazil too. So, fabiobueno, which delivery method did you choose? And were there any surprises ($) from customs?   Many thanks.

Shortly after posting my experience with modding the D2000 (http://www.head-fi.org/t/350721/denon-d2000-d5000-md2000-md5000-appreciation-thread/3105), I have embarked on an alternative strategy. I wasn't satisfied with the added sibilance caused by the original markl mod, even after placing felt...

That may be true. I believe the same (less bass) happens if you dampen the cups with polyester fiberfill or similar materials.

  Thanks for the tip, Mshenay. Although, because 400 dollars do not have the same purchasing power when ordering these things from Brazil, I'll probably have to drop the recable.   I look forward to hearing your impressions of the Vali with the modded D2000, when it arrives!
