Home Amp/Preamp Asylum

Looking for a new Amp or Preamp? If you're after tubes, post over here.

I like the use of separate PSU's for Bass and for mid/treble

This is one of the advantages of bi-amping horisontally. IE one stereo power amp doing bass in L & Right channels. And, one PSU and stereo power amp doing just mid-treble.

The bass PSU may from time to time be a bit stressed when playing loud or complex music. and you won't hear that in the mid/treble as you might with just one power amp.

The half power point is around 350Hz but 600Hz is near enough if using matching amps, the amp doing <600Hz might be working 1-2 db harder on average. But on loud orchestral tuttis it may be working 3db harder, twice the power.

What does the passive crossover in your panels do? Are both the HighP and LPass set to -3db at the same frequency? (It would be a good thing to find out.) If it's not symmetrical the Mini-Dsp box/es may well do a better job of blending them than you can.

You will need a good mike and stand sitting between where your ears will be.
