As the Pi is becoming available in numbers again, we're working on some projects that have been delayed. I can't comment on schedules and projects in work. But I recommend to subscribe on our blog to get updates on new stuff:

Oh I wish you could comment :)
2.1 is exactly what I am in need of. Fingers crossed!
Did you subscribe to our blog? Then you will probably get some news beginning of 2024.
I built a 2.1 system (with bi-amped front using the DSP crossover so does that mean 4.1?) using DAC+ DSP along with 2 (two) of the DAC/ADC add-on boards and external amplification. Seems this add-on is no longer produced. Unfortunate because that was handy for my project!
msquared: I regret not getting the add-on board for the DAC+DSP because my hifi setup changed over the years and I've been stuck with the limitations of the board. What is the DSP product like with the add-on? You are using 5 channels of amplification so still 2.1(L+R+Bass) but a 3 way bi-amped system(LF+MF+HF). How are you feeding 0.1?
Hifiberry: I have waited a long time for the 2x4DSP. If you say there is going to be news on this at the start of 2024, I am looking forward to it. I know you won't want to answer questions but will it be a beta test first for this product?
We have quite a lot in the pipeline right now. The 2x4 DSP is one of four products we're going to launch. Unfortunately not one of the first 2, but I think, we will have beta test boards available in April/May.
I am extremely happy with my hifiberry project! See this image for my design. Speakers are 2-way, so crossover is sending High (Left/Right) and Midrange (Left/Right) to independent amplifier channels which are bi-wired to my speakers. Lowrange is blended (L/R) into a single LFE output to my active subwoofer.
Although everything is working great with my current hifiberry, I would gladly purchase a new 2x4 DSP if there were a hardware way to trigger my amp power WITHOUT polling from Pi, thereby allowing the whole system to operate without connection to Pi. My initial design was driving output pin 16 (currently unused analog out) to a high volume constant tone, where I then had an audio sensing circuit to trigger amp. Unfortunately am just not a talented circuit designer to make this reliable in the face of power spikes with proper delays to quickly soft start, but don't power down during longish quiet audio segments, etc.
