Do You consider the M-100 as a worthy closed portable alternative for the HD650? I am looking for an office (closed) and on the road rig but with similar sound signature as my HD650.

I have the modi, is it really worth upgrading to modi 2/modi 2 uber? I mean only sound wise I don't need uber extra inputs.

Besides BTG, you can try - Forza Audio Works. - Norne Audio if you got $$$ - You can also try contacting Ted Allen from HEADPHONELOUNGE, this is the appreciation thread if you are interested to read reviews about his work.

Thank you its nice to hear that, I agree that the spikes really adds a lot, when I replace the volume knob I will be completely satisfied. On the inside though I still got a lot of work to do..

Thanks, and it doesn't work without the battery? 

I don't get it, how is everything connected  ? 

Original case, the wood that comes with the kit is quite decent and the possibilities of modifying are endless.

Thank you ! Tube rolling is definitely in mind and sadly so as my empty wallet, have to put it on hold for now :P 

Modi ---> Bottlehead Crack + SB ---> HD650      

Guys this product should addressed the same way as the Audio Quest Dragon Fly, if you want to use it on the go with your iPhone for example you need to add the followings-    http://www.head-fi.org/t/634555/ipad-mini-camera-connection-kit-dac/60#post_10365930

I have the HD650, please share your experience with the HD600 when you get it :) 

Can it be used as DAC only as well? 

Sorry but your opinion seemed very conclusive to me, but if I was wrong then sorry, I won't argue with you on Taste on sound signature, I have a tube amp my self :P     IMO the best SS amp I heard with the HD650 was the Naim Dac v1 and it was freaking amazing, that SS amp is the reason I...

      That's incorrect, they come with no cables what so ever, you need a pair of interconnects and a USB cable for the DAC, you can purchase those also at Schiit for 20$ each. I got the PYST USB cable my self with my Modi and I like it, can't testify on the sound quality since I got...

If you want something cheaper, go with the Schiit Modi, that combo sounds amazing to my ears. If you do encounter more Interference issues even with a USB DAC, try to connect the DAC to self powered USB HUB it should solve it.

Thank you for sharing but I am wondering does it worth it when you can buy a brand you pair for 30$ more?

I read some claiming that the WooAudio WA7\WA6 and La Figaro 339 are good candidates to out perform the crack, that price though.  

I was in the same place as you are a few weeks ago, All of the above including AQ dragonfly 1.2 were in consideration. I finally went with the modi and I will explain, odac is a well known dac for its brightness and neutralism, with a bright headphones it might sound harsh anyway some might...

    If you guys want to the BE just buy the BE, the classic are trying to be more like the MK2 not the BE  read - http://theheadphonelist.com/brief-impressions-vsonic-gr07-classic-plus-warning/   You can find the BE in LMUE.

Nice catch, its the MA-1, they are a great value IC's.

Added the schiit modi, new spiked feet and waxed the wood   

Same for me, I just stopped using them with the cables guides, its more comfortable this way. 

For those who waited, WYRD is finally available in 230v Version.
