For the record, we are not talking just bias adjustment here. I use one track on one record for all adjustments. This includes correct torques on the up to 25 fasteners on the LP12 where torque matters, top and bottom of the belt, positioning of the outer platter on the inner platter, siding the felt mat, tracking force, arm height, torques on the power supply, etc. It is safe to say they have heard the first 20 to 30 seconds of this track thousands of times.

The interesting thing is that despite hearing the track over and over, once I get the very last adjustment done - on an LP12 that would be the platter orientation - it sounds so good I want to listen to the entire track.

What record is it you use?

The track "If You Could Read My Mind" by Gordon Lightfoot off the "Sit Down Young Stranger" album.

I’ve got to dig to find that cut. I remember it fondly. I’ve got a large collection of photos I’ve taken of Gordon on Stage. I should dig those out too.

I suppose familiarity breeds contempt in the case of your co-workers.
Keep up the good work!

It’s about the music, not the gear. Just listen - or not.

...for me a disc showing a profound change with correct bias was Mahler 2 on EMI, 1963 conducted by Klemperer. The hard 'grittiness' of the strings disappears, but musically it's better too. So, I would suggest to others trying to establish correct bias, use a disc that is prone to harshness. Once you've got the bias correct then it's time to move onto fine-tuning the tracking force. With an advanced profile stylus (like a line contact), tiny adjustments can make all the difference.

Thanks! I've not dug this LP out in ages, but just put it on - and a tiny, tiny bias adjustment has found the sweetspot. And what a dynamic range on that recording too, I'm probably upsetting the neighbours...

All your discs will sound better now. If you don't already have a digital tracking force gauge it's worth getting one if you intend to try tiny, tiny changes in pressure. What arm/cart combination do you have on your LP 12?
The Mahler 2 disc was a musical revelation to me when I first heard it more than 30 years ago, and Klemperer's 1964 'EMI concert classic' live recording of Mahler's 9th is sonically even better. You may already know that though!

RE: Krystal Bias
It's an Ekos SE with a new Kandid. I thought it was dialled in pretty well already, I've added only about 0.01 to the bias after digging out that Mahler. And yes, I have the Klemperer 9th too, a favourite alongside Barbirolli's. Which reminds me I've not listened to that piece in a long time....

...I like both Barbirolli and Klemperer's readings of Mahler. Not so Abbado. I believe I have 3 copies of JB's Mahler 6 (at least one un-played) on the budget CFP label, recorded in the Kingsway Hall - with it's famous 'fall into' acoustic wonderfully intact even on this 'entry level' reissue.
