The Ferrum HYPSOS made my DAC shine. I have never heard it playing this detailed, dynamic and lively. Additionally, the design and workmanship of the HYPSOS are phenomenal and made me want to give it a prominent placing in my set-up. I can't wait for its release date to finally have it working in my system constantly.

“The Ferrum HYPSOS, is a game changer, not only as an improvement over the standard power supplies, but as a versatile addition to many DACs. The HYPSOS, really is THE upgrade path to take if you want to hear what your digital front end can produce. “

Never judge a book by its cover. The Hypsos really did it. More dynamics, better bass performance, wider soundstage and more space and air between different instruments. A true improvement even vs. the external 12 VDC Battery supply & the Mytek Brooklyn DAC+.

It is unheard of how much good in terms of sound quality such a small device can do. It's not easy for me to admit it, but the Hypsos has sounded better than our design, which we thought, till now, is one of the best ones. This is one of the rare, undeniable proof that quality audio devices are based on the highest level of engineering knowledge, not the ubiquitous gibberish marketing.

"After installing the HYPSOS PS and carefully listening I find the sound of my Mytek Brooklin Bridge better for the following reason:
1. Bass is more deep and more precise.
2. Overall sound is more stable/quite, precise and dark.
3. Sound in combination with Brooklin Bridge is a bit like analog.
To me it is clear the a good and clean power supply is not only important for an amplifier but also for other componets in a good audio system like the DAC & Streamer."
