Aleph Ono
As you can see, my Aleph Ono clone is on mono boards and the PSU is in a separate housing. The phono
circuit has some minor modification to the original, like the XOno. It's a double-sided board with
plated-through holes and a polygon plane on the top. Needless to say, but the overall performance of
this phono-amp depends very much from the PSU. I’m sure, the Ono benefits from separate (L/R) and
external PSUs. I tested different PSUs and ended (really?) with CCS driven discrete parallel
regulators - still prototypes and partly P2P wired.
Really, I have trouble to describe the sound of
this fantastic phono-amp. First of all, it has no sound at all. One of the most striking things is the
way how it presence instruments and especially voices. Each instrument in an ensemble can be picked
and believe it or not, Maria Callas (TOSCA 1953) was staying and singing in my living room. When I
concentrated on it, instruments and actors had body, as though I could reach out and feel it/they
physicality… For sure, this is one of the best phono-amp in the market and by far the best I ever
had!
Many thanks to Nelson Pass and Wayne Colburn for
all their support to us DIYers around the world.
