4-channel Aleph J questions:

I'm in planning process of a 4 channel Amp for active speakers. The idea are to use a
  • miniDsp Flex Eight
  • a 4 channel Aleph for driving mid (Monacor SPH-165KEP, 89db in a closed 10l box) and tweeters Monacor DT-25, 95dB).
  • a 2 channel Class-D 100W for 2x 10" subwoffers. (another project, just for information)

Powersupply: I'm considering
2x Nelsson bipolar power supply, with 1x 600VA transormator (or 2x300)
4x Nelsson bipolar power supply, with 2x 300VA transormator (or 4x150)
It will depend on space in the chassi when everything else are in place.

Some questions regarding the Aleph J:
  • Will the miniDsp Flex Eight be able to drive the Aleph without a pre-amp?
  • Any recommendation for a chassis that can accommodate 4x of Aleph J (both to space and heat)?
