Actually, the term "rolling" tubes refer to the conical rolling motion applied to the top of the tube to pull the pins out without risk of damage. You'll understand if you decide to try tubes.
I gotta say, this thread has been the most fun thread I've engaged in at head-fi.
I've been posting recently because I've got lots of time on my hand after being sacked from job after ten years of loyal service. After sustaining a back injury several years ago whilst over the bonnet of a SUV carrying a cylinder head repair. They looked after me for the legally mandated length of time then sacked me soon after. It's difficult, but head-fi is a great place to meet some great people and share our hobby.
I have given all that I have to this hobby,
everything, trying to understand the technicalities of it all - even though I have no more money, I still wake up with a happy tune in my mind and the music keeps me as exuberant as ever. I love nothing more than to share what I have learned with other fellow head-fiers. Do I regret my decisions - no, not one bit. I'd do it all over again if given the chance.
Here is to the best forum on the netz!
