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?

Dekay- I have the latest Sylvania's (green print)
These came w/the 66 Mag. and the original owner didnt use them as he went with R.T.'s
These Sylvania's are supposed to be the upgraded tube for the magnum vs the non-mag 66.
Although I like Rogue Products,I dont like the tubes they offer.
Mark O. gave me a quad of the Russian NOS 6SN7's he was considering adding to the 99 magnum and wanted my opinion.I felt they were no better,no worse than the NOS Penta Labs tubes that I paid more for when I bought my 99.
He went with the Russians anyway.
The reason I mentioned that I doubted the Sylvania's would not sound too hot is because they go so cheap.Maybe Im a simpleton for thinking that way.
I will give the 'green' Sylvania's a listen this week.
Can you describe the difference sonically between the older and the newer Sylvania's and what the price difference is?
Thanks Dekay,I always like it when you respond to my threads.Happy New Year!

I have some good bids on eBay on matched pairs of 12AU7 Tungsram and the yellow label Sylvania's.
With my Radiotechniques and green label Sylvania's I'll be rolling in tubes for quite some time!
I'll post at a later date my findings.
Thanks Dekay and all others who responded.
