I only have the Brooklyn, not the +.
I am definitely satisfied with the phono stage but I haven't been able to compare anything on my current setup. I am running a Technics SL-1200 MKII with Ortofon 2M Blue, FWIW.
Their literature says it's like a $1,000,000 phono stage or something ridiculous. It's fine. It's transparent and clean. I think you'll need $500+ to beat it, probably. But I'm not sure.
