Hypex DSP module(s)

Is anyone using this as a true pre-amp, and if so how is the volume control and source selection.

My main source is a MacBook, and still unsure if optical out will be better or worse than usb, as the macbook caps one and the dlcp the other to 44Hz?
 
The DSP dedicated power supply is coming this week!
Awesome. Been waiting for it and ready to buy another DLCP board for more channels.

I haven't mentioned it here but I did a comparison between DLCP and Lynx Two-B soundcard a little a while ago. They sound very very similar, at least on my passive Abbey speakers. There's a small difference but hard to put into words. I would say though that the DLCP makes the music sound a bit softer or non fatiguing. There were times I wondererd if the Lynx was a tad more true to the recording with more neutral vocal presentation. I think measurements would be needed to say which is the most transparent one and either way the difference is tiny. However, I overall preferred the DLCP in that specific setup, mainly because it was more pleasant to listen to.
 
Has anyone heard anything new from Hypex regarding FIR filters?

I'm contemplating building a second DLCP for another setup but the lack of FIR makes me question it. I would like to experiment with linear phase filters and one can get FIR quite easy with a soundcard and PC software today.

Considering how long it took for the DLCP to arrive if they are it is probably a long time in the future. If I were you I'd just buy a OpenDRC-DI of separate box or if you want to build the box yourself a MiniSHARC with DIGI-FP and put it in front of the DLCP(s). That is as long as you only have 2 source channels as then 2 channels of FIR is enough.
 
For me too =)

One thing I started wondering about: Does anyone know how the DLCP handles clipping in the DSP?

Can I blissfully ignore all clipping internally and just care about the end result or I make sure I apply negative gain EQ biquads before I apply the positive gain ones? => Should I first linearize the driver response, massively boost the low end for 1-2 octaves and afterwards apply the LR4 or the other way around?
