Best way to warm up the sound

The JD9 has dip switches for loading, capacitance and gain as well as two sets of outputs, high and low gain. Look for the chart concerning those settings and you'll see how customizable the unit is. It's not just MM/MC or Hi Gain/Lo gain, it's everything in between. Rather surprising to me for the price.
My line stage preamp has a tube phono stage and I have a Grado PH1 and a Hagerman Bugle, the Jolida is in another league.

This may sound odd but move your speakers 2 to 4 inches closer together. This should increase the mid bass and warm up your sound.

A follow up .
I installed the new 1.5 ft. LC-1 Blue Jeans cable , cold right out of the box .
A very noticeable change !. The tone is richer and warmer with a darker background and an increase in detail . This is as compared to the stock 46 in. cable that came with the turntable and phono stage . It did improve a bit more after about an hour of play . I am not sure how much of this change is due to the cord length and how much is due to the quality of the cord itself . Never the less , I am happy with the change . Thank you Almarg .
This cord has provided about 20% - 25% of the improvement that I am seeking and is taking me in the right direction .

Any suggestions on what to do next ? TT mat , cartridge , phono stage etc.

Thank you .

Did you check your TT speed? How close is it to 33.3?

No , I don't have the ability to do that . I hope that , being brand new , it would be good .
I have ordered a mat from Herbies per a suggestion above . I'll see what that does too .
