    Liquid Platinum tube amp & AKG K702: Tubes for soundstage?

    I am in pursuit of the ultimate wide soundstage setup. To that end, I picked up a used K702, and it's already incredible. But yesterday I also snagged a good deal on a Liquid Platinum tube amp. It's my first tube amp, so I'm very much a tube newbie, but it's my understanding that there are tubes...

    How do I buy cheap NOS tubes?

    Why do tube vendors get angry or ghost when asking them about brands they have in stock for cheap tube types? It's not like I am asking for detailed measurements or something like that.
