Are there any 6H30's with a sweet upper midrange?

The 6H30 is the new sweetheart preamp tube.
My experience is that the preamps with this tube have a forward, almost solid state type upper midrange.....you know the frequencies at the upper range of sopranos/almost in the sibilance region.
Are there 6H30's that don't do this?

Obviously, it's dependent on the preamp and the implimmentation.

Any thoughts among the tube rollers?

I have heard some people replacing this tube with the 6N6P. Hard to get any feedback. My BAT VK 31 SE uses this tube. I am running a set of NOS tubes but really did not hear much of a change from the factory set.

I am not sure it is a good idea to use 6N6P in place of 6H30.

I would try plugging in a 6CG7/6FQ7 tube into the socket. Draws less heater current than a 6H30, has about the same gain and sounds MUCH better.

Reb1208,

Have you tried this tube in a BAT product? Any mods necessary to run this tube?

This is a very strange idea. These tubes are not even close to 6H30 and their only similarity is their pin-out.
