You're right...the more I look at it, the more options I do really have. I could run 8 of the PLD4.2 amps and hit all the cds, woofers and surrounds and it's acutally not that bad...$10,400 at full retail..likely 8500-9k street. How do the PLD allow you to reduce power internally?? That would work out great.
I actually ran a bunch of options for comparo
1. QSC DCA series a mix of the 1222 and 1622 to get 600w to each woofer, 215 to each section of the cd and 350/ch to surrounds...shakes out as second to least expensive
2. The PLD option above, shakes our to the cheapest option and puts 700each to woofers, 400/ch to surrounds and then 400w reduced however to each cd channel
3.QSC CX series 90w/ch of cd, 250w/ch surrounds and 700w per woofer. similar pricing to DCA option
4.Lab Gruppen C series, highest cost option....onlly by a few hundred $$....125w per section to coax, 250w/ch to surrounds and 700w per woofer in mains. Most ideal power ratios
5. Lab G e series...mid tier as far as pricing goes, supper efficient, but concerns with delivering full power under pushed instances. A little high in the CD power, but not sure they'd provide full rated power...would seem to be more of a sliding scale down as the amps were pushed.
6.Wyred 4 Sound...threw these in for grins just to see compared to pro amps...middle priced as well, compared to the rest..within a grand of the cheapes as a package and also more ideal power ratings per section...150/ch for cd sections, 220/ch for surrounds and 460/woofer in mains.
I just figured it smart to compare a few, highly regarded amps as Mark said instead of just considering price of the Crown Dsi. The QSC PLD is the cheapest option and has what looks to be nice on board dsp for the active mains....I'd have to confirm with Matt that it would meet our needs. The lab c series is my second choice right now (though I'm open to suggestions) and then Trinnov for active mains, or Marantz etc and a separate dsp unit for the mains.
Trying to really think this through this time and buy the right gear, one time
