This is very bogus notion. If the 6E5P is somebody’s idea then would be not me but Dima’s as he discovered the tube “for Sound aplicatios” in 90s while he was fixing a TV. However, your approach, Jim, is very strange to me - who care whos idea it would be. Do we care about respect to Sound of about a bogus content of artificial egos? I think you confused my site with DIYAudio…

Seemed to me there were enough 7788 around on eBay and whatever. I am also using it in a DAC output stage. Gain and driver in one. I needed 30dB or so and then a reasonable output drive. The 7788 has both. I like it better than the 12aX7 gain into 12AU7 cathode follower I had previously used.
I do not believe in driver/input stages neither around 12aX7 not around 7788 or the rest low-biased, low-power tubes. Run 0dB out of your DAC and see what will clip first - output transformer or driver stage. In a proper design the transformer should choke first…
