Be honest please

List your system, then I'll decide if the question is worth answering. ;)

"I can't stand when those vintage guys boast how great the receivers were from the 70's. I owned some of those receivers as a kid and I can tell you they don't hold a candle to what they are making nowadays."

Maybe they buy vintage gear because they prefer it. Also, I don't think you would take issue with someone for "boasting" about equipment you like. After all, your opinion is fact.

I don't look down on people finding gear at low or no price.
In general, however, bragging is not a pleasant behavior to endure.

Should that bother me?

Like the old saying goes," ONE MAN'S TRASH IS ANOTHER MAN'S TREASURE."
