Which miniDSP and how to connect it...

[WeekendWarrior]

I've got a Topping D90LE, Pre90 and LA90D connected to a pair of Ascilab C6Bs, and am also running a pair of MJ Acoustic Pro 50 Mk 4s active subs, currently via a high level speaker connection. I've setup the subs according to manufacturer's instructions, taken REW measurements and implemented left and right EQ corrections via Roon's Procedural EQ. I have no ability to high pass the C6Bs, so set the low pass filter on my subs to 60Hz. I must say it sounds good but as ever with this hobby I wonder if there is a final improvement to be had by adding a miniDSP/DIRAC for potentially better sub integration and room correction, including the ability to high pass the C6Bs (probably at about 100Hz).

I'd like to keep my D90LE and LA90D, although could replace the Pre90 for a miniDSP of some type. I can see that the SHD Studio, which is a digital only processor could work, although I'd have to add a second DAC:

However I'm a bit confused which other miniDSP devices would work and how I would connect them to retain the D90LE and LA90D, so I'm hoping the miniDSP experts could help?

Thanks in anticipation...

The obvious way to do it would be to replace the D90LE/LA90D with a MiniDSP SHD, which is itself a high performing DAC.

MiniDSP's version of Dirac doesn't include "Dirac Live Bass Control" if that's important to you.

Whether you'd get a noticeably better result this way is probably a coin toss, and dependent on whether you like what Dirac does compared Roon's filters.

Do this. You will save money, reduce the box count, reduce power bills, and have 2 less power buttons to push.
