The Amp

I came across the UCD 400 class D amp from Hypex. It is a 90+% effective amp as small as a cigarette package and weighing no more. They have perfected the concept to a degree it can now be found in high-end stereo amps and in mono bass amps. You can look up these amps and read much more at the website of HEVOS, an outstanding manufacturer of bass amps. Basically they combine a 12AX7 tube preamp with a class-D amp into a top of the bill lightweight rackunit. It is a very nice product with a reasonable price which makes it very tempting if you're looking for good gear. I have bought all the components for my amp in rotterdam at Speaker & Co, who were very helpfull. The tube preamp I bought is of the shelve and does a good job as I am already using it for a couple of months now. Originally I was going to integrate the amp into the Monolith but have now decided against it in favor of a rackmount unit.
