    Audio components for connecting multiple subwoofers: Double Bass Array and DSP

    Perhaps my request is too specific regarding the Double Bass Array with CamillaDSP. It would already help me to know the best way to get 4 separate or 6 separate channels. For instance, I could use an audio interface via AES digital into the DAC. Is this maybe an idea so that I don't have to...

    Audio components for connecting multiple subwoofers: Double Bass Array and DSP

    I currently have a system consisting of an RPi 4 with moode audio and CamillaDSP connected to a Topping D90 III Sabre. I want to expand this system with a double bass array consisting of 4 subwoofers with DSP. I know that there are Hypex FA251 FusionAmps with their own DSP, but I would prefer to...

    Topping D90/A90 with Power Amp and Subwoofers

    Can somebody explain it to me, why this works?

    Understanding Low Gain and Preamp / advice on amplifier selection (Benchmark AHB2 or the Apollon Hypex NCx500)

    After carefully reading through the thread, I've come to the conclusion that one definitely shouldn't adjust the volume at the beginning of the chain. So, not in the DSP of the source before the DAC. In my case, using the RPi4 with CamillaDSP. Or should I understand it as adjusting each...

    Understanding Low Gain and Preamp / advice on amplifier selection (Benchmark AHB2 or the Apollon Hypex NCx500)

    That's a great thread, but it doesn't answer my question as to why there's no volume control on the amplifiers. Because if the amplifier is the weakest link in terms of THD, SNR and SINAD in the chain, then one would need to reduce the volume or gain there. I gather from the thread that it's not...

    Understanding Low Gain and Preamp / advice on amplifier selection (Benchmark AHB2 or the Apollon Hypex NCx500)

    I don't fully understand the concept of Low Gain and which devices are needed to implement it. That's why I'd like to hear your opinions and experiences on this matter. Initially, I found the Topping LA90 discrete particularly interesting in Bridged mode as 2 mono blocks, which would provide...

    Tube amplifier loses bias on one tube and starts humming.

    Thank you for the quick advice. I could have figured out the tube swapping on my own too. Sometimes, however, one is like an ox in front of the mountain... Fortunately, there are such good forums where even with such specific topics, help is quickly available. For now, I swapped tube 3 with 4...

    Tube amplifier loses bias on one tube and starts humming.

    So far, I have been very satisfied with my Destiny eXperience MKII. However, I have now noticed a hum on the left channel. I thought it might be due to bias. While measuring and adjusting, I found that the third KT88 tube has no bias. What could be the reason for this? I have also discovered...
