If you love music and enjoy it then keen and enjoy the amplifiers. They have character! Unless there is a significant other in your house that dont like the look of them...
Getting back to the original poster's topic, allow the man to attempt to get the best price for his pair of Leak amplifiers.

Regarding tracks to showcase equipment: there are plenty of other tracks with wonderful sonics
I am working on it. The fees will be determined by what we want to apply it to.
