Here is an alternative but relevant point of view on this Marchand analogue active crossover, for anyone considering going active with DSP.
One thing I can say about the analogue active approach, it knocks spots off either miniDSP 4x10HD or Hypex DLCP DSP systems, if you use a turntable/phono stage. I've tried both these DSP set ups and the analogue inputs ADC on both is just not good enough, like an after thought, actually more like a joke they are so bad. Turns a decent vinyl set up into entry level sound quality, in one easy to program step. The Hypex (no longer available) handles analogue better than miniDSP but that's not saying much. Both sounded good, very good in fact, with digital sources, but they are not for those that have analogue I'm afraid, a seriously large backward step if you try.
I now use a Marchand XM44EMB for LP bass and passive filters for mid/twt, this allows a low powered valve amp for mid/twt and a beefy class D for Bass. It may not be for everyone, but this variant of the Marchand unit works for me, when DSP didn't. I use a Rod Elliott designed PSU for my Marchand board and populate the plug in crossover modules with Polystyrene caps and Takman metal film resistors, both rated at 1% but I grade them further to +/- 0.1%. The Marchands basic technology is DIY friendly for upgrading components, where DSP units tend not to be, unless you are an EE or very accomplished amateur.
No Audible background noise close up to the speaker, when the Marchand is in circuit, which is more than could be said for the miniDSP.
There doesn't seem to be any negative impact on the performance of my vinyl set up, or my Okto DAC8 Streamer for that matter.
So different strokes for different folks I guess, but worth mentioning.
