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 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.
I've tried many different tubes and have settled on two Tungsram 12au7's and one Tungsram 12ax7 (welded). Very sweet, full, accurate sound, with great soundstage and highly accurate timbre. BUT of course the sound is somewhat system-dependent!

When you're talking "sweet and warm" I would suggest a pair of British Mullard 12au7's, NOS. Approx. vintage 1960-1965. Talk to Andy Bauman of Vintage Tube Services. I talked to him at length about this, and these are what he recommended. I have had several pairs of these tubes and they seemed pretty consistent in sound quality.
What do you folks think about the Amperex Bugle Boy Vs Genelex Gold Lion re-issue?
