Help. Wife says Teres 340 Is too bright.

My Teres 340 is equipped with a Origin Live Illustrious 3 arm and Benz Ebony L cart. The rest of my system is listed.
I think the TT combo sounds great. She does too, but says the highs are just a little bright. I have played with VTA but that has not fixed the problem though she says we were headed in the right direction with tail lowered.

She says that we had the Scoutmaster just right prior to buying the Teres. Funny thing is that I thought the SM was a tad bright on certain albums. But she didn't. Now I think the 340 is just right but she thinks it bright on some recordings.

The only component that I can think that would be causing this is the tonearm. I cannot imagine the Benz Ebony L as bright. Nor do I think it is the Teres. I really think we (wife & I) need to have our ears calibrated so as to agree on brightness. But since that isn't going to happen, I suppose I should figure out how to please us both. So, do you think I'm on the right track with the tonearm being the culprit? What tonearm would give a warmer presentation? Thanks for your help
