...I'm just setting out the question so when other folks get their amps up and running I want to know if they encounter noise issues and what they may need to do. If they work fine with single ended cabling longer than a few meters then I will be encouraged to try them out.
Certainly a balanced system reduces possibility for noise but I cannot go there and want to see how others fair. I think it is a potential issue for others to know as well so I'd like to see users tell us their configurations so we can see how this pans out....
Even with identical systems, ambient noise, and listener sensitivity, RFI in one location may be far worse than another. Does this not prohibit making reliable conclusions based on another person's experience?
Too bad I had to return the AKSA Naksa 100 stereo amp today...no A-B when Ncore arrives later.
I did not relish returning to the YBA amp for all three channels (Trinaural). I use two monitors per channel in a strange ambiance array (description and images after I paint the stands). Two monitors parallel = 2.7 Ohms minimum @ 200 Hz/flat 4 Ohms > 600 Hz.
I changed to series for 10.8 Ohms/16 Ohms. Sensitivity dropped as expected, but performance definitely improved. Not up to Naksa levels, especially in the treble, but better, cleaner, more natural, less strained at all levels. Interestingly, peak power is about the same, 4 or 16 Ohms. I suppose current limiting @ 2.7 Ohms and voltage limiting @ 16 Ohms yield similar peak SPL.
16 Ohms also improves speaker cable performance vs. 4 Ohms. Expressed as a ratio, cable resistance vs. circuit resistance is 4x lower on 16 Ohm load vs. 4 Ohms.
Which load better suits Ncore?
