I put the YO186 back to the use. The sound was fine but it had that a fine over glow of spoiled fall colors that I described before. It was not disgusting, in fact pleasurable but a bit too much.
Then I asked to myself what happen and why this effect shown only last week. A week ago I freed up the playback ground, letting it to float, and felt that it cleaned up my MF very nicely. So, why along with clearing up of MF I got deviation from chromatic neutrality. I was thinking, thinking, thinking and then it come to me that this a bit overly-sugary touch of Sound very reminds me the situation what my Injection Channel provide too much output.
Now, I do not play games with Injection Channel riding up and down – it set at very precise level, giving very accurate amount of specific colors to Macondo. Why the striping ground noise from MF would impact it? It shall be affected. Still, it is very easy to try and I dropped 2dB on the Reds’ outputs. The sound instantly got fixed and not just fixed but become supper good. It has the new MF clarity but at the same time it has right, non-exaggerated chromatic density. Very, very nice.
Of cause next I grounded my playback with one single path. The colors got dropped immediately and I was forced to add more output from my Injection Channel to compensate it.
This is very interesting. For sure the ground of my amps does not affect output of my amps. However, it looks like with cleaner MF my YO186/S2 tandem has different tolerance or need for injections of colors. Still, my MF with floated ground is still benefited from my Injection by it looks like at 2-3dB less. I did a few adjustments of proper level of Injection with and without ground and the effect was very repeatable and predicable.
Very good. It looks like I have cranked this problem, even though I still have no explanation for it.Rgs, Romy the Cat
