I own the Pass Aleph 0, these are Mono's, but before these I tried various amps , bi-amping and so on, so I can say in general:
When you go for another Aleph 3, everything will be better ( better focus, better dynamic and bass, larger soundstage, better timing and so on ).
It is a much better choice, when you have a amp you really like, to buy another one, this is for 95% better, than to sell this good sounding unit and to go for a different brand. The story will be the same again, that another one of this one will make a improvement, too, but only, when this one is definetly better than the Aleph 3.
The only step above this is going for true mono amps.
( Or go for high impedance speakers, they make life much easier, and you will hear much more ....)
