It looks like a debate to me.

Kaitty's system: Grado SR60 or 80 utterly mediocre headphones with the foam ear cushions removed and a Sony Walkman CD player. Right Kaitty? There might be green sharpie on the edges of the  CDs which certainly elevates this system to true High End so yeah, he knows what's what.

I've earned my stripes by being a sought after and sometimes chased after (Get him! That concert was too damn loud!) live sound mixer/producer/destroyer. I've had my stripes ceremoniously ripped off in front of royalty also, along with banishment to an isolated island from which I escaped. Long story...however, I'm firmly in the single ended Tube camp which interestingly is a camp with a single end that sounds like music.

Oldguide...you can report all you want but keep in mind there's a tradition of free speech in some places, and to some a troll is anybody who doesn't agree with their particular point of view. Are you reporting anyone who seems passionate about something you disagree with? A self appointed judge of others is also a troll, and nobody needs to be looking over their shoulder to see if Oldguide the Church Lady is watching for tawdry posts.

It should be "tubey or not tubey."
