Title: DSP crossovers and Phono Stages.

DSP crossovers and Phono Stages, share your thoughts....

It's a big compromise to the phono signal?

Thanks, appears that did not make any difference when listening, even with the errors that appeared on the measurements..

I hope that will appear more users of DSP with phono stage here on my topic, and share their experiences..

Yes, classic question!   :lol:

A few years ago, after moving into a new house ... I had to move away from active speakers which had a 3-way analogue XO to a 4-way miniDSP setup (as I added a pair of subs and had to delay my main speakers to time-align with my subs).

Before the change, I had no digital:
* phono stage fed the preamp (together with other inputs)
* preamp fed the 3-way, analogue active XO
* active XO fed 6x Class AB monoblocs.

After the change it was:
* phono stage fed the preamp (together with other inputs)
* preamp fed the analogue inputs of the miniDSP
* analogue outputs of the miniDSP fed 8x monoblocs.

I then changed the way I was using my miniDSP unit - by feeding my phono stage into an A2D converter and thence into the digital input of the miniDSP.  IOW, I was digital as much as it was possible.

There were certainly no negatives in this change - only positives!   :)
