Power Amp recommendations?

[Bob Lee (QSC)]

I don't see sensitivity listed on the Demeter preamp specs.

Demeter preamps have pro line-level output sections and are capable of producing a very hot level. This makes concern about power amp "input sensitivity" moot.

I can confirm this from direct experience with my HBP-1 and a handful of different power amps.

So not to beat a dead horse, but what exactly am I matching to the input sensitivity of a power amp?

For example... what would match up to the XLS Drivecore input sensitivity of 1.4 Vrms?

(this is just out of curiosity at this point... I'm 99% sure I'm buying the Demeter preamp)

Spend some time over at TB'er Bongomania's site. He's got some great essays about what this all means and how it works for those who may not have the experience:

You're not really matching anything.

The preamp should be capable of putting out a signal level equal to or greater than the power amp's "input sensitivity" spec--assuming that you want to be able to drive the amp to its maximum, at least now and then.

Unless your preamp is among those few that for some reason have an inordinately weak output section, it's not a problem.
