Plinius Hiato

Off hand what brand/model would be a good upgrade from the Parasound Halo?

Pass is also Mosfet, I think.
Seeing now your looking at poweramps, a step up would be the JC1 Halo’s in high bias Class-A mode.

This is Stereophile's quote to the load the Montis present.
" Either way, that this speaker is a difficult load for the partnering amplifier to drive is compounded by the high electrical phase angle"

The Martin Logan’s can go down to 1ohm load, with very high - phase angle from 1.5khz to 15khz
The best is the Halo for these impedance’s as it uses Bi-Polar output devices which are better for this type of low impedance, the Pinius I believe (check) uses Mosfets, not so good for low impedance’s. Don’t bother with tube or Class-d.
