A valentine poem to tubes

Roses are red, but the music is warm,
Glowing tubes delivering sweet sonic charm.
Strings sing so sweet,
Bass vibrates your feet,
Each note's a caress in this audio balm.

Transistors may boast an efficiency claim,
But tubes whisper secrets, ignite passion's flame.
Harmonics alight,
Textures take flight,
A soundstage expansive, defying all name.

So crank up the volume, let melodies flow,
With each blooming ripple, emotions aglow.
Roses may fade,
But the music that's made,
Is a love song, eternal, which kind tubes did sow.
