Siemen tubes in Sonic Frontier line 2 ?

I have a SF line 2 and I am considering replacing tubes with Siemen tubes. How will this effect sound? Any other NOS tubes to recommend? George2

Siemens worked very well. I tried Mullards--and they worked like an antenna, picking up a lot of noise. I spoke with techs at SF and they said that the Mullards are a known problem with their gear.
