-Audio & CInema Portugal

"The Ferrum Hypsos power supply has certainly convinced us in terms of sound and user-friendliness."


"The Wandla-HYPSOS combo is a thoroughly, wisely engineered converter that made me look forward to using it and made me smile every time I did. At its best with the HYPSOS, the Wandla danced in the same ballroom as DACs costing over $10,000. Sincerely recommended."


"The ERCO is a complete DAC/AMP unit. It isn’t the cheapest, but it will get you to the higher end range right away."


"Ferrum fully preserved the soul of the music, the warmth it’s definitely there, an open and wide soundstage didn’t run away, its frequency response felt complete and perfectly balanced and the only thing that was missing the fun was listening fatigue."


"The ERCO DAC is neutral to natural, accurate, and articulate. Its amplifier has bags of power to drive just about any headphone you want to throw at it. It is also incredibly simple to operate right out of the box."


"All-in-all a very good amplifier and I look forward to seeing what Ferrum Audio comes up with next. A matching DAC maybe? To the Recommended Buy List it goes! The OOR also wins our 2021 Amplifier of the year award!"


"WANDLA is about the music…and the emotions attached to it. It’s here for the fun times, and if you’re already thinking of getting one, then prepare to be converted by the real thing."
