Best mellow sounding 12ax7 for Thor TA-1000 preamp

I just bought  Thor TA-1000 and am very impressed with the resolution but want it to be more mellow sounding... Darker and less treble emphasis. Can anyone recommend the most musical but mellow/organic 12ax7 for the Thor? When I bought it the unit has telefunkens. The outputs are already mullards so I am focused on the inputs.

It is feeding vtl mb-185 signature amps and quad esl63 with vandersteen 2wq subs.

Thanks!

I own a Thor TA1000 Mk II and its one of the best preamps I ever owned. I did have to do some tweaking to add some warmth but at no time was it ever bright or harsh. It's very detailed and with excellent separation and air but to add some warmth I am using Brimar 12AT7s and RCA 5751 Triple micra Black Plates. also add a good power cord, I am using Cardas Golden Reference. Also Amperex 12AX7 Bugle Boys are a good choice. Also a good choice for the 12AT7s.
Remove the Telefunkens.
