Headphoneus Supremus
I sold my Mjolnir 2 after spending a month with BasX A-100 , doing A/B comparisons. This amp is legit af!
Y'all I bought this headphone amp and I couldn't believe it's selling for this price. It is a DREAM with the HD600s. The HD600's no longer feel dark or laid back. It simply came alive. Soundstage, resolution, unlimited dynamics. Oh and really low bass. Just insane really. Imo to beat this amp you are going to have to swing up to a Schiit Ragnarok. It has got huge amounts of power capability and I believe this is the reason the HD600's came alive. Lots of control.
I removed the jumper and absolutely heard a difference in dynamics - there was no smear. Just lightning quick transients. The first time I felt my headphone rig was not second class to my speaker rig. The jumper limtis the current output of the A-100 to prevent high sensitivity headphones from frying. Not a problem for the HD600. With the jumpers off, the A-100 pushes a godly 1300 mwatts in to 300 ohms. Doesn't sound like much? Check out how well other amps do at 300 ohms? You'll be lucky if they squeek out even a 100 mwatts. I've seen amp units that gasp out 14 mwatts at 300 ohms.
At lower impedances the A-100 will push 8.5 watts at 50 ohms more than enough to fry the headphones. Hence the jumpers to prevent over driving lower impedance headphones.
But with the HD600's....it's just a dream.
Speaker and DAC rig: (Axiom M80's fully balanced to Emotiva DC- to XPA-1 gen 2 monoblocks in class A mode + room treatments. With a source the Musiland Digital Times via BNC output. About a $4500 setup). I can't believe I'm saying this but it absolutely competed with this nice sounding speaker setup. In some aspects it did better as well.
I dare you to find anything close anywhere near that's price range.
Love it!
Along with the huge torroidal transformer, you will see that it has a ridiculous 20,000 mf of capacitance and that performance really shows bringing very low bass and extreme control to this set of headphones. The treble also really opened up. I am definitely hearing more air. The control allows everything to sound holographic with large amounts of layering. The fan is there for safety but it never activates.
