Been a/b testing the Ferrum oor + hypsos against the Xi audio Broadway balanced. Choosing between them is going to be my first super hard decision in this hobby.
My main setup is rme adi 2 akm + external Amp and abyss diana Tc. I do want to upgrade my dac but haven't found a suitable replacement yet.
In short, the Ferrum oor + hypsos and Broadway both sound engaging and detailed and are worthy of being end game experiences (that or I've sated my spending lust atm). While same in being super great, both have some wins over the other.
The Ferrum oor + hypsos stands out in its elegance, sounding overall refined. I would guess that most audiophiles would choose it over the Broadway.
Bass - deep extension & full sounding and some physical "mmph", round shape
Mids - not overstated but tear jerking "real" vocals. Voices are defined well and I was able to hear the "air" in the singing. First time listening to music made me imagine the unknown face of the singer, or the existence of a piano in front of me.
Highs - detailed and controlled. Only the worst recorded tracks I had could sound sharp(literally clipping instruments). Everything else was refined and controlled.
The Broadway in comparison stands out in its blast energy and vocal forwardness. The intimate mids and impact energy are making it so hard to leave this guy.
Bass - so much energy and great texture some heavy tracks gave the feeling of pressure on the ears. Extension actually wasn't naturally as big as oor but slight eq to lift the sub bass made every aspect of Broadway bass significantly superior to oor.
Mids - intimate in-my-head vocals. The oor is like a beautiful singer on stage(not that far but still some distance). The Broadway is like a personal seranade right in front of me.
Highs - detailed and refined.
The oor is more natural, beautiful in its nuance and controlled sound gives a feeling of elegance.
The Broadway is somewhat surreal. Some sound effects and percussions don't sound like a recording, they sound like they're in the room with you. But that somewhat recesses the non-impact bass (which is why it doesn't seem to extend as far as oor) and also pushes back everything surrounding the vocals. If you listen to a busy track / mix, the vocals are very clearly cut out and presented in front of you.
Also been struggling to hear the difference that the 22-30 volts and respective wattage changes in the oor but haven't tried the non variable power supply yet.
