I would like to reform the way I listen to music today and migrate to a Roon platform. What's holding me back is that I don't understand if I can have endpoints that can implement FIR crossovers and output over a multi-channel DAC, the way I do it today with JRIVER convolving filters created with Audiolense. So let's say my bedroom system consist of a pair of 2-way active speakers, where each of the 4 drivers is driven by its own Class D amp, which amps in turn are fed by a multi-channel DAC (like the miniDSP U-DAC8) connected to a NUC running Win 10 and JRIVER for convolver duties. Today, this is a DLNA endpoint (through JRIVER) but it is my understanding that this doesn't work with Roon, where Roon needs to own the queue and the endpoints are stupid. So how could I achieve this with Roon? Convolve at Core/Server level rather than at endpoint? I know Roon can convolve but can it convolve multiple filters and streams for different rooms/endpoints in parallel? Can Roon even convolve a stereo signal into a multi-channel signal or is it limited to stereo output only (i.e. room correction but no crossovers)? Do I need to involve HQplayer somehow? Ideally, I would like to use RPi 3/DietPi/Roon Bridge endpoints but I doubt they would have the CPU power to convolve say six channels of 131k tap FIR filters. Even if the Roon Server could convolve, is RPi 3/DietPi/Roon Bridge compatible with any multi-channel USB DACs? What about Signalyst's NAA instead of Roon Bridge, does that change anything? Or could I just install Roon Bridge on a Windows 10 NUC and use JRIVER WDM output to a multi-channel DAC? If that's the only way, I'll go with that, but it's just not a very elegant solution....

Hi. My apologies if this is the wrong place, it is my first post. I recently got in to computer audio by wanting to use a very old Audio Alchemy DAC-in-the-box that was sitting in my closet collecting dust. I bought a NuForce U192S they had on sale for $50 over at Audio Advisor. The combo sounds much better than the 'audio out' of my Dell Ultra Small Form Factor PC even through some old Altec Lansing computer speakers. Soon I upgraded the speakers to some equally old Optimus Pro X77 metal cabinet speakers that I had lying around. The foam surrounds were shot, so I upgraded them with some Dayton drivers from Parts Express. I have a small decent 10W amp driving the old X77s but will probably soon replace with a Topping TP-21 desktop amp or the Emotiva x100. Well, now I want to add a sub, but I really would like a small desktop crossover so I could play with the crossover point on the fly. I found a Rolls SX45 that would be perfect but sadly the reviews say it sucks. I was thinking perhaps a 1/2 DIN old school car audio equalizer/crossover but thought I would see if you may recommend something better. I'd like to stay small (like the size of the Audio Alchemy DITB) and relatively inexpensive, say under $200. Any thoughts? Thank you in advance. -dave

Were the existing driver and firmware for Allo Piano 2.1 created by using Purepath? If it were, what Biquad filter subtypes were set, Butterworth, Linkwitz, or other mixed? Or what are the filter types of the crossover. The last question is about PurePath. Are there functions to create time group delay between 2 and .1?
