We have pushed the concept of the Impulse stereo power amplifier to its extreme and developed an all new 1.600 VA power supply with a true power regulation. Thus, the TIDAL Ferios mono amplifier board is certain for all practical means and purposes to be supplied with never failing power reserves and a lavish feed of clean current that will drive every imaginable speaker with ease.

The generous supply of additional power is merely a welcome byproduct, really. The real goal was the absolute relaxation with which the Ferios performs, to the extent where any attempted description of sound attributes becomes meaningless. The Ferios is quite simply benchmark with regard to amplification in this size.

FERIOS SPECIALTIES

At TIDAL specifications and specialties are in the end of the day only single aspects to form a complete result out of it. And such thing could not be brought down to single parts or numbers. This would be like making conclusions of the wine by eating the grape the wine was made from. But afterwards one can find some details to give at least some small background informations.

Hearing is believing.

“The Holy Grail of amplifier design is to build one that furnishes ample power without muscularity becoming the product’s defining attribute, without tonal neutrality, natural detail, and that hard-to-define metric known as musicality taking a back seat. Tidal’s Ferios monoblocks provide 300 watts of continuous RMS power into an 8-ohm load, 580 watts into 4 ohms, and more than 700 into 2 ohms—enough to assure authoritative control of any consumer loudspeaker played in a real  world domestic environment. Each amplifier has two regulated 800VA power supplies and a whopping 410,000µF of capacitance. The Ferios features a DC-coupled input circuit, without capacitors or relays in the music’s pathway from start to finish. Likewise, a proprietary protection system does its surveillance without touching the signal. The result is an utterly effortless and transparent magnification of the fragile electrical impulse presented to the amplifier, whether the power required is two watts or two hundred. This makes for an exceptionally relaxed presentation that allows a listener to devote his psychic energy to making an emotional connection to music. Yes, the price of admission is high, but if it is within your means, you’ll never look back.”

“The Prisma preamplifier and Ferios power amplifiers are among the best electronics I’ve heard. They combine a startling immediacy and transparency with a tonal beauty that simultaneously engages the head and the heart. Their resolution of individual instruments within complex arrangements was sensational. I was particularly impressed by the Prisma preamplifier with its sophisticated volume control and unique integration of the phonostage that greatly shortens the signal path. If you thought that the phonostage inside a full-function preamp was compromised compared with outboard units, you haven’t heard the Prisma.”
