I think I know what Kyrill is trying to say.
There does seem to be a bond between us audio nuts that grows into friendship rather quickly.
I have made many friends, some of them have grown to be very good friends, thru music and audio.
Audio bonds us, but later it develops into a regular friendship that involves our families and other Friends.
Look at the rave meetings, that is a lovefest to a small degree. Of course eating and drinking and BSing are a big part of it, but out of it I am sure many have made real friendships.
I made a friend in Pittsburg over the sale of a pair of speakers, now we chat once a week and he and his wife has stayed at my house for a weekend(for Phil's rave) and they will be back in Sept. for my rave, and I know I have an open invite to their place.
Remember, these are strangers, and yet I allow them to stay in my house with my wife and my kids, and yet you know they are good people.
Do you know how much equipment has been left at my house buy other audiophiles to play with?
Chris,(Lonewolf) was the first person I met that lent me equipment,, a Modwright and a Butler,

then Jim, (Hogg) again always leaves stuff, now my other friends always leave stuff, and I find myself wanting to lend my stuff out when I can, just to share the experience.
You don't really KNOW these people like people you grew up with, or family, but somehow you trust them, and they trust you.
So ,Kyrill, I know what you mean, and I have seen it in action.
It is no man love thing, but beyond that, and I think that is what has kept me so interested in this hobby, the gear is cool but impersonal, and the music, well you just want to share.
It happens again and again, I meet the coolest people, in the same boat as me.
Its a crazy hobby but a good one
