When set to max vol po, kojo has less power than x3 1.7V lo.
I will try to use with hm901 later.
AnakChan is right, the lo of hm901 is very powrful.. I think maybe full 2.0V

You are welcome
Ko Jo KM 01 is very good amp

Mid : natural and analog midrange , sound so full for iem like headphone
Bass : very Good bass detail and very deep bass impact
Separation : very good that you can hear the music placement in the right place

I love this set up for long listening

Minus : Sony XBA H 3 fitting is not so good and can not use for sleeping

There's yet another interesting portable amp with very powerful output and a nice match for the ODAC

There's another super crazy high power amp card for HM-901/HM-801 to be available in 2014 and that should be called U235 card with whopping 6V output

http://www.erji.net/read.php?tid=1433688

How do we actually know whether that's too much power to damage another amp's input or not?

Besides, is triple-amping causing any potential problems?

HM-901 headphone amp card > KM01-BRASS > ALO The International

About your question I will answer by tomorrow

I am sorry , I have not tried your dsd music file to drive my abyss

Rudi do yourself a favor and audition or get an AK120-S. It is just sick ;).
