1 + 1 = 3 :)
Today I have tried these two items as the amplifier arrived today. I have tried the amplifier "MENG Series X1 6P1" alone via a cd player with eminence alpha 12 a, motorola piezo bullet tweeter. First I tried the amplifier alone and it was fine.
After I connected the Xiang Sheng "728A" preamplifier. The sound quality has improved and also the audio ouput. This is the only valve preamplifier that I found with bass and treble tone controls.

x  y = 0 2x  2y = 0 2x  2y = xy 2(xy) = xy 2 = 1

Almost, but not quite. In the last step, you are dividing zero by zero (since xy=0). Zero divided by zero is an indeterminate form, and those can only be solved using limits and calculus (for example, L'Hôpital's Rule).

If you have twins, you can get 1+1=4
2+2=5 for extremely large values of 2, apparently. 1+1=10, and 9+1=A. Also, 9x9=51 Seriously, though, it's nice to hear someone has put something together that they enjoy.

Binary and hexadecimal! Yay!
Oh, and there are 10 kinds of people in this world: those who understand binary, and those who don't. Kyle
