Oh yeah it could be that, maybe I should've got it without dac card.
Though honestly it's not bad but definitely warm. Like after coffee sit about 10 minutes then it's perfectly drinkable temperature.
I think even on 2nd day (today) it seems to sound a bit better..... I'll keep listening..... lol.
I think they're actually polar opposite LOL.
At the time I bought Concero HP for convenience (USB powered). But once I saw the announcement of PMax I was hoping it would be a direct upgrade from Piety, so that's when I ordered it. Though it's actually not the same sound signature...... more on that in the bottom.......
Otherwise between Concero HP and PMax.
- Concero HP USB powered, PMax has its own power cord.
- Concero HP is brighter and VERY airy sounding, treble forward presentation, PMax is slightly darker warmer smoother sounding.
- Concero HP pair better with darker headphone, while PMax pair better with brighter source / headphone.
- Concero HP has horrible digital volume knob, PMax has good analogue volume knob.
- Concero HP is dac/amp while PMax is amp only (optional dac card).
- Both has wayyy too much power for my headphone (TH900), but PMax has even more power if switched to high gain.
Uh something to keep in mind is that if you really loved the Piety, expect PMax to be different.
PMax is more neutral signature (compare to Piety). It's still warmer than most amps out there, but definitely less than Piety.
Say for example on a scale of 0 to 5.
0 being neutral 5 being like tube warm.
0 is like THX AAA
1 is probably like Magni
2 is probably like Asgard 3
3 is probably like PMax
4 is Piety
5 is probably what you'd expect from "tube sound"
This is slight generalization the values might be slightly off, but you get the idea LOL.
