I ditched mine for Lindell. Mine was fairly noisy. I know the originals were as well, but the Lindell was only a little more dough and I think it sounds better. I originally going out of the ISA one, so it wasn’t a noisy preamp issue. Take it for what it’s worth.
I’m not experiencing any noise issues with mine. I record vocalists in a vocal booth which is pretty darn silent. The mics I use have an a self noise of between 6dB-A to 12dB-A and my preamp is a Cranborne EC-2. My interface is a MOTU 828es and I’m also using high quality balanced leads.
