Is there an audiophile channel? My father recently passed away from cancer leaving me his set up but I'm struggling to get it working after having to unplug everything to shuffle it. Looking for someone to give me a hand but can't find a channel that might be able to help 🙏

Sharing my interests will make more people want to follow me.

By no longer working I mean the sound is passing through to the speakers but at a very low volume and lacks body or clarity. I'm not a complete idiot so we can cross out turning it up as a potential solution. I can also confirm that sound is coming from both speakers.

The set-up
1. The mac mini passes the audio to Minerva DAC via the firewire

2. The DAC is passing to the Conrad preamp via the channel outs to aux 2 (this is how dad always had it). The red & white leads into the matching red &  white connectors on the DAC and Conrad. Conrad has aux2 set as the source.

3. Conrad preamp has the main outs connected to the custom tube amp with the red and white leads connected to the corresponding red and whites on the aux input. Can confirm the amp is set to aux for source.

4. Tube amp has the speakers leads plugged into the corresponding black and red connectors.

I THINK the issue could be that lead from the Conrad to tube amp connector has a pretty shoddy soldering repair job that he did but it was working previously with this issue so I'm not sure if this is it. I'd happily buy a new one but I'm unsure what the cables are called to be buying a new one.

Happy to take any suggestions or even just to hear that I've done something really silly and need to swap some cables around.. Please don't mind how messy everything is, I've had to pull it all out of it's shelving while I mess around with it.
