Herron Audio...Still in business

@gera - try keith@herronaudio.com. I've got a phono preamp and line stage preamp from Herron Audio. He's pretty much retired, I think, but he's still happy to answer questions about his gear. 

Thanks! I’ll share my findings with other Herron users.

There's a BIG difference between products no longer made and products no longer supported. Having support is what's most important to me. Having this mindset can also discount many things from the used market that longer have support from the manufacturer. Why stop there? How about 1- or 2-man boutique companies? When the founder passes away or retires you will most likely lose all support.

Update:

I sent an email to Keith at Herron and he responded quickly, answering all my questions. I'm glad to say that he still supports his products (I have the M1 amps).
