record out on integrated amp


I am interested in potentially trying to use an integrated tube amp as a tube buffer to feed the ss integrated via the record out of the tubed unit. I know the record out is not volume controlled.
My question is does anyone know if the record out of the tube integrated amp would go through the tube circuitry and will retain the "tubiness" or it's basically just a pass through from whatever it is fed into it?

Thanks

In case anyone is interested. I picked up a Yaqin Sd-CD3 tube buffer off of amazon. On my SS amp it did not make a huge diffeence. It was a slightly softer sound and reduced the hardness in the high frequencies when pushed. Overall a slight but audible difference. Little good little bad.
However I now have it hooked up with my tube integrated and it is a night and day difference! Bass is now tight and has texture and tone. Everything is tighter, faster and more focused through out the spectrum. I am shocked. No shit it sounds like a new amp.
I must say that I am surprised that the addition of a buffer improved the sonics to that extent. Not questioning your result, just surprised. I am curious: What source (s) are feeding through the buffer? How much gain is afforded by the buffer? What speakers are you using? Thanks.
I was very suprised as I was dissapointed in the performance with the ss amp. One thing is that I based the ss performance with only an hour or so on the unit. When I hooked the tube amp up it had been on overnight. I do not believe the buffer has any gain. I am feedig it from a wyred4sound dac-2 into cayin A100T with kt120s pushing golden ear triton 1s.
