Dirk Sommer tested the power supply in his system on other components and shares his listening experiences with you and me in the following: "Since Helmut Baumgartner, whom I used to think of as belonging more to the CD player than the streaming faction in the Hifistatement team, has recently become more involved with music files and their playback, the Aries G2.1 is missing from my chain for the first tests with the Ferrum HYPSOS, because it is currently in our photographer's living room, just like a G1 and the Melco N1A/2EX-H60. For the time being, the Waversa Wrouter, which is also active as a switch, takes over the function of the streaming bridge in my system. One of its USB outputs then goes to Chord Electronics' M-Scaler, which is powered by its standard external switching power supply and processes the signals for the DAVE, which is now powered by a linear power supply. In this configuration, Patrice Heral's 'Improvisation' from Michel Godard's album Le Concert Des Parfums, for example, sounds a little less thrilling than usual. Also, I'm sure I've been spoiled by a touch more bass pressure before. But if I really want to treat myself to the highest level of musical enjoyment, the M-Scaler is not powered by its mains adapter but by battery packs: the upsampler reacts quite sensitively to its power supply.

This is immediately confirmed when the HYPSOS delivers around 13 watts to the M-Scaler: The soundstage now seems much wider and deeper. In terms of dynamics, emotionality and punch in the low frequency range, no wishes remain unfulfilled. Thanks to the rumbling timpani in a large space and a shakuhachi - a Japanese bamboo flute - even "Raijin" from Arild Andersen's album Mira becomes a musical and sonic delight. This does not change when one of the Poweradds instead of the HYPSOS power the M-Scaler from rechargeable batteries: The probably imaginary soundstage retains its impressive dimensions, the fine resolution is at least as good as with the Ferrum, which, however, has a little more to offer in terms of dynamics than the battery pack. From now on, I don't need to worry about charged power packs. The HYPSOS provides more comfort and also a touch more pressure and speed. Great!
