One thing I pity did not have the chance was instant switch comparation between ANALOG xo and those DSPs. That would be quite interesting.

The miniDSP I brought had a gain stage inserted using TL072 op-amp. So the test somewhat provides some insight about its transparency...?

I admit I have strong bias about electronics being generally transparent. Although I had been caught with this as well, when using some "Sherwood" amp that someone gave me. My point is these electronics may provide a "micro difference" where I'm more interested to "macro difference".

Replacing dome tweeters with a compression driver would be a good example of "macro difference".

Good point.
And is this not exactly the outcome of this test?
Thet they sounded pretty much the same, and will therefore be equally good building blocks in a digitally cross over system.
So use these as the tools for making the macro differences, by using your prefered speaker units.

And as always remember the macro differences made up by the room acoustics, and the way they are treated.

Good thread

PS. And Merry Christmas to all

That is exactly my takeaway from these excercise.

First, that I hear no difference between direct wire vs. DSP (yes, with ADC->DAC)

Second, that it does not matter which DSPs to use. They sound the same.

That comes down to price and functionality, where MiniDSP is superior.
For example DCX can't do Linkwitz Transform which I consider very important.
But DCX don't need a laptop so it may be useful in some situation.


One DSP which was an outlier was the DEQX. I think it is either faulty of there is some missing configuration. They sounded "strange".

new to the digital crossover game...

I'm totally disappointing by the products companies offer and the complexity to have a decent home studio active crossover setup at reasonable price... the market could be udge if a ES9018 minidsp 8channel with FIR and phase correction appear at like 800$... but for now...

can't believe the stupidity..

it's not like it's a new domain... companies should know what is needed like passive volume or 32bit volume not to loose bitdepth or good digital input to bypass tons of conversions that color the sound or a good dac... etc....

to think to have a decent setup i would have to pay 2500$ just for the crossovers more than twice the price of my speakers... kinda freaky..

or diy my way thru hell..
