So I was on eBay shopping around for phono preamps and stumbled across something that looked like another Chi-Fi box. Upon further inspection, it appears to be made in Massachussetts by hand. https://www.darlingtonlabs.com/ There are three models right now, the MM-3 - $119 (currently listed at $99 right now on sale) MM-5 - $199 (currently listed at $179 right now on sale) MM-6 - $329 Now all of them are 40 db of gain for moving magnet carts for 47K + 100pF loading, however 150pF, 220pF , or 330pF available upon request.Not much change between specs, although slightly lower THD, lower noise, and closer to RIAA spec. All run on a 24V AC adapter/step down transformer. All hand matched discrete parts. Says using NOS JFET's, although does not say what exact ones (ie, 2SK170), and if is not that, I am sure it is something similar. It also looks like they have more products coming in 2021 - "Moving Coil Step-Up stages, Headphone Amplifiers, and DAC Analog Output Electronics."
