McIntosh Vintage C22 Telefunken 12AX7 or ECC803's?

Anyone try running Telefunken ECC803's tubes in the vintage McIntosh C22 pre-amp? The C22 is currently running Telefunken 12AX7 tubes. I am curious if there is a big audio quality impact with a swap especially in the phono section; the ECC83's are super quiet hence perhaps a good match for the phono.

I currently run 801's, 802's and 803 in the MC275 and the impact is significant with the 803 contributing the most.

As larryi said there is no ready supply of NOS/OS Telefunken 803S. They are truly rare not the BS rare you see in ads. The cost is astronomical as well.
I can help make a tube recommendation if you provide what you want the tube to do to your sound. Telefunken ECC83 12AX7 types are indeed kind of steely. They provide a clear/clean and strong signal.

You are trying the right tube for low noise and clean signal. If you can get ECC803S, then more power to you, they are selected for the reasons you are tube rolling.
