DSP advice needed: MiniDSP 4x10 HD?

Hi,

I'm looking for a DSP with at least six outputs. At the moment I use a MiniDSP 2x4HD, but I would like to compare my 2-way hybrid loudspeakers with my transmission-line loudspeakers, so I need 6 outputs.

There's also the MiniDSP SHD, but this product has only 4 outputs and I don't need a streamer. There's also a 4x10 with Dirac, but I'm unsure if I would like Dirac.

Any ideas what alternatives there are? Would a 4x10HD a good choise for doing listening tests / comparing loudspeakers?
