Some 2 channel Pre-Amps have a “Home Theater Bypass” for “proper” hook up between an Amp and a preamp. As far as I know the prime has no such bypass. So when using G91A you are going through two preamp stages. And knowing Meridian, their input on prime converts it to digital. So you go through extra A/D and D/A.

So yeah if you “A/B” G91A to Prime in that setup of course prime will win because you put the G91A at a disadvantage. I’m sure it will work and for movies probably not a big deal. But it’s generally not a good idea.

If prime has a true home theater bypass (i.e. a input to output relay or switch to shunt input to output) I stand corrected.

If you think listening to music is fun, try learning an instrument.
