K&K Phono Preamp questions.


On the front of this unit there is a polarity + mute and - knob. Is the polarity + and - in regards to the xlr outputs? Also on the back panel, there is a switch near the xlr pin 1 ground label. Is this a ground lift switch? Any and all help and other pointers regarding this unit are more than welcome. Thank you.

@wturkey,

Millercarbon is correct, it's all straightforward. Which do you own, the Maxxed-Out or the Trio? I own a Trio.
Thanks for the feedback. I'm not sure which exact unit this is. It's got the 2 cork knobs on the front. It's very similar to this unit.

Thanks again for the help.
I can tell you that you have one very fine phono stage. I have owned mine for 20 years and is now the maxxed out version. I have no desire to change to anything else.

Looks like the one you have is a pretty old version. Don't know how it compares with the new full PCB-based ones.
Gotcha. Thank you for the feedback. This K&K is a difference maker. As soon as the unit was fired up, it was a wow moment. Any tube recommendations from current or past owners? No idea what tubes are in this unit. They sound quite good, to these ears anyway.
