tubes for ART Pro MPA

JJ Tesla ECC83S tubes for ART Pro MPA mic preamp

Has anybody tried the new JJ Tesla ECC83S tubes yet as a replacement to stock OEM ones?

I want to replace the tubes in my recently-acquired ART Pro MPA mic preamp. The only experience I've had in "tube rolling" (as the audiophiles refer to it) is replacing the stock tubes in my VTL TL2.5 stereo preamp with NOS Mullard 12AT7's and 12AU7's. BIG difference! Tighter, punchier bass, lowered noise floor, more detail in the treble, overall it was a terrific cost-effective upgrade for my audio system.
