Do I have enough power?

I think Bggregory is on the right path.

Mani's I have heard of McIntosh amplification lead s me to believe the might trend towards being a touch bright with some amps (similar to my Dynaudio monitors) and digital sources. Not a good or bad thing inherently. Tube amp might sound good but would need to be beefy to always sound good in any room with any kind of music. I'd go with a beefy high current capable SS amp and tweak things from there using setup, ICs, pre-amp, DAC as needed until dialed in.

Challenges with manis:

1) right amplifier for best (not just good) performance with all kinds of music at target listening volumes

2) Need distance to walls for best results that justify the investment (not an unusual thing at all)

3) THey can sound a touch hot and less laid back compared to some lines, like PSB, for example in some setups, especially with some SS amps. Addressable via many common tweaks as needed though, nothing unusual there either.

I would love to own Mani IIs as a possible step up from my current smaller Dynaudio monitors if I could justify the expenditure. Maybe someday.
