MiniDSP for filtering

Have a look at WAF Najda
48 / 96 / 192 capable.
It depends how DIY capable you are.
2 x 4 as standard can be extended to 2 x 5 channels.
It's the real deal SQ wise.
The built in DACs are v good.
Sound wise it was as good as, and considerably better than my favourite DAC and pre, costing many many times more, once you use the X/O, time alignment and room mode taming capabilities.

The Op amps can be upgraded using Burson discreet op amps.

Is the DA-converter responsible for the lower sound quality of the 2x4 HD compared to the 4x10? Would, in that case, it be an alternative to get a nanoDIGI 2x8 B together with separate DA converters?

Another question: I would like to use the IR remote for volume control on the 2x4 HD as I will connect the digital output of my CD player, but would this affect the sound quality? (making signal smaller = less bits)

i find najda is very good and on par with deqx but less expensive. Although deqx does measure driver response and correct phase errors. Also room correction but I never used that. I don't have personal experience of minidsp. Anyone who claims to be able to hear any fault with dsp has my sympathies.
I am using najda as a dac at the moment but got it for speaker projects when I get time for them. It has a very good dac.

Good DSP I agree with Paul.
Beringer 24/96 had noticeably poor SQ. The auto time alignment was fun though..

Mini DSP could be good, certainly the better one.
I was put off by all the SW plug ins, seemed an over complex sales approach. That and the location.
Najda is Europe and has 2 DIY audio threads as long as a hundred arms to read about and learn from and ask questions to.
I guess there are similar for mini DSP though?

There is a miniDSP forum, lots of knowledge and helpful peeps.

Whether you want Phono or balanced outputs (or both) may effect your decision.
miniDSP also do a plate amp with on board DSP. Meant for Sub use but would work providing the max crossover point is high enough for you, would need investigating. Hypex do something similar, which will probably be a little more expensive. Worth checking both these out as it could be a compact DSP/Amp solution.

Does it have digital outputs to allow you to use DACs of your choice?

why would you, the dac is excellent.

[iansr]

why would you, the dac is excellent.

So you've got 2 DAC options, an excellent one and one that one of the world's leading DAC designers has been developing for about 4 years to make it as good as he possibly can. Which would you want to use?

[Magna Audio]

There was much discussion about which DACs to use on the DIY audio thread at the time.
You can argue that one DAC is technically better than another till you're blue in the face.
The best sound discussion boiled down to how the DACs were implemented in the total solution.

You can change them and I've seen Najda builds with 5 standalone DACs, but that was a lot of work.

The main mod is changing the OP amps for Burson discreet jobbies.
That's just an unplug and plug in..

Najda's analogue volume control is good. There's the ability to control each sub channel independently in analogue too.
Perhaps the others can do this too?
