Try those taps also since you got the sinking but keep them in use only if you find the result bit more open in the treble. Else its just a waste in heat that it will be felt after you push the mA to high hot-rod.
Cool, thanks for that. I was just a bit concerned when the voltages weren't over 10v as mentioned. Didn't think there could be too much wrong as it's doing everything right.
Still evaluating but from what I'm hearing I'd say it's added more accuracy to the music, placement is more precise and there seem to be more micro details coming through which adds a lot of nouonce to vocals ect. Hasn't really done much to the sound stage, this was already very good.
Happy so far.
Thanks to everyone for making this available.
