Pass Aleph3 vs. X150.5, AtmaSphere MA1

I own a Pass Aleph 3.0 .
It drives the 4 ohm load of JM Lab Mezzo Utopia speakers.
The amp sounds a bit limited in output current.
Due to this reasom I am coinsidering a potential upgrade
to the Aleph 1.2 monoblocks .
Or shall I upgrade the speakers to the 8 ohms Alto Utopia Berrylium which is a better load for the Aleph 3.0 and then keep it.
Not quite comment on what you brought up for discussion but
it has something in common ....

Not exactly but have something to say and ask.

The other 2 amps can be more powerful for your speakers.
