My Cornwall 4 tube setup:
Primaluna EVO 400 pre and power.
Amperex "Bugle Boy" in the two center gain positions on both amps.
Old metal base GZ34’s in the rectifier positions
Sophia Electric blue bottle EL 34’s in the power amp
Vintage "Western Electric" cloth covered tinned copper wire for speaker.
SR "Purple" Fuses throughout system.
Shunyata Delta NR V2 power cables throughout.
Old Shunyata Hydra 4 conditioners for everything but the power amplifier where the cables go straight to wall.
I grew somewhat weary though of having to wait hours for the Primaluna transformers to saturate sufficiently for real "bloom," but when they did it was quite something.
This system is now sidelined for a SS setup built around Holo May DAC, Holo Kitsune pre and Audion MK3 monoblocs - an equally spectacular setup that is easier to manage.
The Borresen X2 speakers have been getting good reviews and are about the same price.
