Equalizer in a Hi Fi system

A used Charter Oak PEQ-1 has popped up online. Sold by Guitar Center in Pt SAint Lucie FL. I will call tomorrow and find out what serial number and if it’s one of the good ones Mike Deming made. 

@ellajeanelle I'll leave a link for you.I  bought it as a step up from the Lokius,which was my first tentative step towards parametric equalizers. I was skeptical about adding another cable and component but curious enough to try it for a modest outlay.The API is a "no frills" unit which is all I need for a home stereo.You folks that do recording will be looking at equalizers with more features I imagine.What surprised me and why I love it is how simple it is to clean up not so good recordings - uncongest them.I've only had it for three weeks so I'm pretty much gobsmacked right now.https://reverb.com/item/42746954-api-select-sr24-dual-channel-4-band-equalizer-api-562-eq-inspired?bk=eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiIwOTljYjJhNS1lODA1LTRiYWYtOGM2NC0wOWRhN2RjNzFjYTQiLCJpYXQiOjE3MDgwOTQ0MTcsInVzZXJfaWQiOiIiLCJzZXNzaW9uX2lkIjoiYzU0YWMwODctMDY4Ny00YjViLTliNzgtNDJhMWI5MTZhMWY2IiwiY29va2llX2lkIjoiYmYyMzM3YjQtMjc3Ni00ZWJmLThkYjktZGU5OWVhMTliOWQwIiwicHJvZHVjdF9pZCI6IjQyNzQ2OTU0Iiwic291cmNlIjoiTk9ORSJ9.Fh3bZbkJYtNrjKlrA_4NiZiIHGfMK2uwRtUQ2ImAbJs

I have called about the used Charter Oak PEQ-1. It’s the right serial number. Deming era. I own 2 already. I am likely going to scoop it up, as it’s the best sounding studio stereo program EQ I’ve ever heard. That is, unless @mirolab wants it. Miro…?

Actually never mind, @mirolab. The dealer at Guitar Center called and gave me my requested test results. I asked for a number of things to be done. There is disproportionate hiss in right channel. It’s audible with quieter passages of music. That’s not acceptable to me. I asked them to service it and get back with me. We’ll see. But not now. Sticking with the Michelangelo buildout. And my 2 wonderful Charter Oaks. 

@mirolab , can you or anyone else enlighten me on how sound engineers can run several pieces of gear in series in their chain, sometimes like 8, and not have to worry about degradation of signal. This is as opposed to we audiophiles worrying about only one extra box in the chain. If I chained 3 pro EQs together and did mids on one, air band another, etc. would I have viable result?  Or do the pros use special consoles for daisychaining that prevents degradation?  It’s common practice to use a few EQs in the production process!
