Equalizer in a Hi Fi system

Yes, agreed to all. But I love having hi fi tone controls. I have learned in my experimentation with many different pro EQ’s that some certainly are more appropriate in post production playback than others. I think the less complex EQ coupled with good circuit design and quality parts can lead to a very musical and gratifying listening experience. While more complex instruments with more functions and more filters can be too clinical or analytical. My next steps in my hi fi evolution are trying room corrective digital EQ as I’ve previously mentioned, but at least as important, upgrading speaker cable or even speakers and streaming sources to provide the higher fidelity foundation BEFORE any EQ is dialed in. Luckily, I have had for a while now a SQ that I’m really into in a big way. 

Hi Guys,

Just stumbled across this thread. 

I designed the PEQ-1 for Mike D way back when.  It is pretty much a "fit/form/function" copy of the Pallette preamplifier.  Per Mike's request, added the switchable frequency center points PLUS the top end 50K freq he wanted.  

Made up one for myself, sans transformers, in a small box like the Loki.  Have that on the end of a 25ft umbilical so I can use/adjust it from the listening position - with an in/out switch and gain trim for both channels.  Still use and enjoy it after all these years.  Yep - PROGRAM equalization, when necessary, works for me.  Glad you enjoy it also!

Thanks for sharing!  Very cool. I own 3 CO PEQ-1 now. Nothing else sounds quite like it!

If you're able, suggest bypassing either the input or output transformers - or both. Never liked their "sound"

Personally a fan of trasnformer coupled inputs, especially their rejection of ground loops.  If you bypass either, do the outputs.

@stellavox1  - Any idea who made them?
