  1. I can't imagine anything we get frustrated about in our lives matters.
    All the time spent taking into consideration the several things that people experience every day is in fact undoubtedly
    necessary, as no other man is going to encounter existence
    for us. I feel that folk have to be even more mentally
    stable. Technology is fantastic, yet so much of whatever we think about is so abstract.

    Having a cup of coffee is a zen process that takes one back to the present occasion. We have to be more
    in the here and now, without being overcome by our lifestyle and
    the episodes we experience each day.

  2. These are the real deal. Beautiful Blackburn tubes. They sound fantastic in my Audio Note OTO. Lush but not syrupy, dramatic. Never boring. Got a closely matched quad, well packed with lightning quick shipping.

  3. I liked the first quad so much I ordered another as a backup. The second quad is just as good as the first - same date codes and tightly matched parameters close to the first quad. Best of the best. Not many of them left in the world in this pristine condition. I am surprised they are still here.

  4. I could not resist and got another quad. It is such a joy to get truly NOS tubes of this quality and condition. EL84-wise I am now set for life :)

  5. As a new explorer of NOS tubes for my Leben CS300xs, this is one of the wishes I'm eyeing. Thanks for the level of details provided at this site.
