To me it sounds fine, maybe even nice but somehow flat and uninvolving. The music does not flow, no emotion, no extreme 3D and separation.
Classic Aleph P 1.0 I have sounds much better to me.

I tried to come back to B1 many times but it's always the same. I still have it somewhere laying around.

Just build another /diffrent project, maybe it's not for you.
k thanks for that, what would be a better project for sure?

But not if that doesn't happen with another preamp in the same system.

I have no idea, it probably all depends, i belive some are extremely happy with B1 and it depends on the system and preferences probably, it is just you are not alone what i wanted to say. I'm not impressed with B1 that's it, does not work for me. I belive some Pass production preamps to be better than B1, maybe not in every system but most. I have no idea what to recommend, maybe others can help what other preamp might be worth of building if B1 does not work for some.

Assuming that it is working correctly, the B1 is very neutral. It's not even
really a preamp - it's a buffered volume control. There are plenty of people
who aren't looking for that, and it's no problem by me if they prefer something
else.

I told you many posts ago to measure the Vgs. See post4.
Have you done that yet?

You use a pot with the B1 ? If yes is it mono/stereo and what is the rated impedence of the pot(s).

I had a lifeless B1 (again very subjective opinion totally based on one's chain) with optical volume control (impedance of ~13k). Swapped the optivol with 2 mono Log Pots of 25K impedance each and things became a LOT better

which I guess makes it more a matter of your source output

Well i'm not so sure, with DCB1 and the same source and the same optivol, the performance is extremely good.

But then what do i know
