Help With DSP Options


I’m looking into trying some DSP, but not sure what’s out there that fits my needs. I want to keep the signal digital till it reaches my dac.  I also need the DSP to output over usb. This is where I’m having trouble finding something unfortunately. I can find a few products that keep the signal digital but none that output over usb. I don’t have a large budget right now, around 500$.  Still interested in hearing about more expensive units though. If out of budget but otherwise the right fit I’d be willing to save for a bit before purchasing. Also curious peoples thoughts on how a DSP might impact the sound outside of its DSP capabilities. I don’t want to loose transparency by adding the DSP, so hopefully that’s possible. Looking forward to what you guys can come up with.

Your easiest path is Roon.

Getting a DSP unit with DSP out is harder than you’d think and AFAIK this has to do with the need for a real CPU and driver to talk to it. The USB handshaking and protocol is complicated.

If you can forego the USB requirement, the miniDSP SHD is excellent.

Another choice is to stick with a PC source and use DSP capabilities of JRiver or MediaMonkey.  You can even get DiracLive software that is PC based.

Sorry, mistyped.  I should have typed:

Getting a DSP unit with USB out is harder than you'd think ...

The reason I’m looking for usb out is because my dac has a reclocker option that only applies to the usb input.  A pc isn’t really an option I am open to. I don’t have a pc to use for this purpose. I also don’t really have a good place to put a pc close to the system either. 

If it uses an asynch sample rate converter, I'd say you are trying to use a feature that helps with bad data, but with good data gets in the way. 

I tried an ASRC, and with a modern DAC it had no benefit. With an older DAC it helped with lo-fi and low rez sources like a Google chrome cast stick for instance.
