To my finding HE1000 with Mytek Brooklyn beat both HD800 and HD800S.  But please note HE1000 after burn-in period (300-500 hrs) will sound much much better than the new one.

  The sound differences are not big but the price differences is very big .... (facepalm)

  Please google it. 

I've read the white paper that usb3.0 generate a lot of RFI/EMI when in use.   How you guys deal with this interference issue from usb3.0 standard that might affect the sound quality?   Thanks for the answer in advance.

This "REclock" is very interesting. Can't wait for it.

Range : Micro Product : New iUSB   Reason: The prize = new iFi product + Gemini => It must be the new iUSB for sure.   PS. When will you launch the iPower 12V version?

^ Agreed.

I think $5,000 for New Closed back flagship and $50,000 for new Orpheus. But the new closed back is a wireless headphone!!!

I pre-ordered it already ... just kidding. :D

For me V281 has a warmer sound compare to Taurus Mk2 and has a better output power.   At that time, I changed my headphone from HE500 to HE6 and HD800. I found Taurus was a bit brighter when using with them and I had a feeling that it can't drive HE6 to full potential, so I sold it and bought...

Between those choices, I would definitely choose V281. I owned Taurus MK2 and V281 using them with my HD800, LCD3F and HE6. V281 is a winner. I also tried Ragnarok with HD800 and LCD3 at the local shop here, it sounds very good but V281 is better in both sound and build quality.

You made the right choice. For me I don't regret when I sold my Taurus MK2 and bought V281.    I used it with HE6, LCD3F and HD800. Taurus is very good but I found more enjoyment in music when using V281.

I don't understand what is your issue but Taurus MK2 has a brighter / leaner sound compare to V281.

  Hello olor1n,   How did you revert it? Did you revert from 1.50 directly to 1.39 or 1.50 > 1.43 > 1.41 > 1.39?   Thanks 

  I already have a very good customized C.A.P.S. (I spent $2000 on it). I also tried other DAC like Auralic Vega, Ayre QB-9, Mytek Manhattan, Invicta Mirus, Weiss DAC202 all of them are better than M51 but for me I don't think it worth to pay $3000, $5000 or $7000 for that gap.    So I think...
