Yep. Differences of opinion make the world a more colourful place

(BTW I agree mini dsp really is off topic)

A lot of interessting reading so far but If this thread should carry on lets stay on topic.
Checklist for whats already done:
1: Powersupply for all parts.
2: Software (fir).
3: External dac's (with separate clocks to be used or not).
4: Usb reciver (with separate clock to be used or not).
5: Master clock (to be used for dsp only or as master for all).

So, what parts and how to make them work together ?

Remember we are not aiming for "good enough".

And yes, "Minidsp" is of topic.

re software FIR: I dont know if we should strike it off completely. is there any reason to rule out a cooperative effort between software and hardware? as in correction curves and convolution/impulse responses are worked out in conjunction with an ADC and computer, but then loaded into a DSP which nolonger needs the computer anymore for the realtime processing..

afterall an impulse response doesnt need much by way of memory to be stored in the DSP and then the audio is processed in realtime, rather than having to process your files offline, you just store the IR offline and its then used along with the DSP EQ/filter curves to produce the final result.

I didn't mean my comment that way. I meant I think the software (DSP processing) could do with more than just FIR

Ok, about software. I just picked one out of two from post 44.

But the core DSP is simply the best, at the moment...!
Thanks
Derek.
I had the DEQX HDP-4 at loan recently. I wasn't very impressed considering the price. It was pretty good but not worth the price in my opinion. It did not sound as transparent, open and homegenous as my Lynx Two-B soundcard connected straight to poweramps (using digital volume control).
I have also tried GroundSound and here the difference was even larger. I woudn't be surprised if the most expensive 8 channel miniDSP is better sounding then both of these.

I'm also waiting for the perfect all in unit. I guess I could set up something with PC software and use a high quality soundcard, but I would prefer something separate. The coming DCPL from Hypex is interesting, but I might need FIR filters for my planned bass system. This is also a product I'm looking forward to:

Might one ask what the rest of your system consist of - and what your reference and goal is. Or is it only the theoretically optimal DSP that you want to discuss?

You have Trinnov, but you are paying a lot for room correction.
