Does bitforst MB need 5 volt from usb to work?  Thanks

Any reason why BRZ instead of AN?   Yeas LME49860 sometime can be too sharp for ears.

@DDDamian , change your single op-amp to AD797.  Has more dynamics and speeds with better detail, slightly less warm.  If you want more sparkle, you can add LME49860.   I suggest you give a try.    I am using AD797, LME49860.  Few people here using the same.  I have been trying different...

I like warm sounds.  H10 for me with HD10.  I also use Yulong DA8.  and using xlr interconnect.

  Looks great!  Maybe we can order from you :)

  Thats interesting.  Picture pls.  :)

Try changing NE533xx opamp with OPA2604.  Or change your dac.  I like DA8

Any cable that bring analoque signal impact sounds.  That is very easy to notice.  But for digital USB,  i cant find any difference till now

This is what works well for me.   Single channel - using AD797 Dual channel - using 5532 ( more detail compare to 2604) or opa2604 (smooth warm sounding)   Thanks

You would need two.   Where are u from Jazz?    I buy from http://www.rs-components.com/index.html   See if your country is part of the coverage

  This is my finding, which I guess will match your finding.  My other amp, has more mid and bass compare to H10 but it sounds the bass is not well control feel bloated at times hence giving warmer sounds feels.  on H10, the bass is well controlled, tight no more bloated bass hence feel less...

  Mark's finding is interesting.  H10 didn't sounds thin on my HD600.  It is the opposite.  I am using 797 and NE5532 btw

  What is your DAC?  But yes, that's a strange finding.  My gustard with HD600 is far from thin.

  I am using +6.  Work best for me

  Have 2604 with me for few days but have not put it inside.  Still on 823 + 797.  I will buy LME49720NA as well.   I am aiming at some DAC as well.  Currently using citypulse.  and planning to get power conditioner.
