Sweetest sounding 12AU7?

I have a Rogue 66 Magnum that came with Radiotechnique tubes.I have had these before in my old 99 phonostage along with some Telefunken 12AX7's
The old 99 phonostage sounded very good with this combination.
In the 66 linestage the R.T.'s sound somewhat bright.Im not sure how many hours are on them but I know they are fairly new.
Im wondering what a good 12AU7 would be for the 66.
I also have a pair of Sylvania's that came with the 66 but havent listened to them.I would guess they arent that great.
Any leads for a sweet and warm 12AU7?
Anyone have experience with Tungsram?

I'll be rolling in tubes for quite some time!

Life is good!

Back in the late ’90s, Andy from Vintage Tubes sold me a half dozen NOS Mullard 12AU7s for my preamp (along with some Amperex 6922s for the amp) and I remember feeling that the sound I got from that combination was warm and musical and rocking. "Sweet" may be subject to whoever is defining it, though. That was a long time ago, and I cannot remember what vintage those 12AU7s were. I understand that one needs to be patient now a days when buying tubes from Andy, but I suppose if you told him what sonic qualities you were looking for, he would have something for you.

When Uncle Kevin was selling a lot of NOS tubes, I remember him raving about Cifte 12au7s and also Brimar 12au7s, but I do not recollect him using "sweet" as part of his description.
