Fo...It really depends on what you are using it for. For simple audio systems the shared ground works perfectly well (most audio switches on the market are made this way). If you have inputs like an HDMI switcher, that will negatively affect the ground so a 3-pole switch is ideal for that application. For the last decade or so, I just use 3 or 5 pole (bal) switches for people's custom switchboxes just in case. It's a bit more wiring and the switches are more expensive, but better safe than sorry.

The potentiometer could very well be the culprit. There wasn't much real-estate for a larger pot if I recall correctly. You could pay a local solder slinger to potentially move back the circuit board and replace it. 2 hours of work in the U.S. would be ~$170 plus ~$20 for the part, which is the cost of the amp. It's hard to recommend that course of action as I don't know how reliable the other parts of the amp are, but trying to find an adequate replacement at this price level is also very difficult, so it ultimately comes down to a roll of the dice. I'd say based on the probability the pot being the culprit and having no issues for another 5 years, vs. buying a new amp, the later seems safer in my very humble opinion. This is unfortunate as I strongly believe in keeping old equipment alive, but we don't have the documentation necessary for a proper investment vs. risk assessment in this case.

About a month ago, a crackling noise is coming thru the speakers regardless of volume setting. I have switched out speakers, cables and even remove the line input to the amp, but the crackling still persisted. I've contact Emotiva for support, they indicated that since I don't use my unit that often, that the volume potentiometer might be the issue. The tech ask that I rotate the volume knob from max to min for a few minutes to see if that helps. I tried that, still does not work. Since this model is discontinued, he indicated that he can get a $50 trade-in for a newer unit. Apparently, this is somewhat of a common issue, just google "Emotiva BasX A-100 crackling noise". I really like the form factor, styling and class A/B operation of this unit. At this moment, I don't know if I want to go with another Emotiva amp again since the previous one only lasted five years with very light use.
