The Pass Aleph 4 is a design that is freely distributed and discussed by the great Nelson Pass himself. With a bit of hunting and frugal purchasing it is very easy to build a £15K amplifier for a fraction of this cost.

Here is my Aleph 4 which cost me just under £500 to build. OK it uses a lot of second hand components but isn’t that the DIY spirit?

The finished result is A++ PERFECT and sounds WONDERFUL.
