Hi,
I have finished my Stereomour II build. I use it with two Pipettes, one Sublime+Subette. Initial build sounded amazing. It reminded me Bottlehead Crack in the lushness of the sound. My concerns that 3.5 W won't be enough were gone. It was absolutely loud enough.
Few days later I've installed a shunt regulator expecting Speedball-like improvement. It was complete in one evening.
Now I am not certain if I like the change. There are two distinct issues:
1) Omph is gone. I don't mean the sub-bass, that is delivered brilliantly through Subette. It is a bit higher frequencies from low end to mid range. The sound is "thin". It might be more correct objectively, but it's is less euphonic
2) It seems to be 80% of the previous max volume. Now I can find some tracks where 100% volume is not actually loud. Previously there was a certain headroom.
The tests pass, so I don't think shunt regulator is installed incorrectly. But maybe the issue is more subtle.
Now I have two questions.
1) Is some max volume loss expected?
2) Is there a quick way to disable shunt regulator without resoldering it all the way back. Maybe it can be operational, but is there a way to temporarily bypass it for testing by shorting past it somehow
Crack after a Speedball sounded if anything, but more powerful. Here I feel some loss in power.
Thanks
