Thanks for the info. I'm having the same issue and it has been explained very well here. Just one last question : Is it safe to completely remove the series resistor ? if I don't put any series resistor on + and - (5K on the example above), there will be no gain loss right ?
If you have a little bit of excess gain, then a max setting of -1.2dB is an advantage.
Gain = 20*[log10{0.87}] = -1.2dB
Did not get a chance to edit out the error due to the posting delay exceeding the 30minute edit time.

Hi Andrew thank you for advise and help. My system sounds great now. May I ask, between a 10k pot and a 100k pot is there a huge difference ? Especially so when the new CD player I am getting have a +4dB strength. Thank you in advance for your advice.?
I don't have the track law values.
You need to do the attenuation vs rotation measurements and calculations for the two alternatives.

Really green diyer here, so please don't bash .. : )
Read the posts, understood the wiring and the math, even made up a simple XL sheet to do the calculations for me (given the amp Zin and pot impedance, use goal seek to find resistor values, to go for the 0.87 gain = -1.2 dB).
Then stumbled on this X3 multiplier, that ruins the perfect -1.2 dB in hschaser's math. Why is that for? Wasn't there in AndrewT's brilliant explanatory post No 16...
