Norma Audio REVO IPA-140 high-end erősítő
The Norma REVO IPA-140 integrated amplifier represents a definitive choice for amplification. Considered the ‘big brother’ of the accomplished IPA-70B, it is easy to think of the IPA-140 as an IPA-70B with more power but this amplifier is the result of an ambitious and uncompromising design brief. It’s a 140W per channel, fully dual mono integrated amplifier, using a sextet of MOSFETs on each side, giving the amplifier a potential burst power of 1.5kW. The amp is essentially two mono blocks sharing a common front panel, sitting in a non-magnetic, solid aluminium chassis. Norma has gone with a high-bandwidth design (>2MHz) and has built it to last with elements like sealed and very long-lasting gold/palladium relays for source switching.
Its power output of 140W/8 Ohm gives it the ability to drive demanding speaker loads and therefore make it an extremely versatile amp. Versatility is enhanced by the ability to customize the input/output connections and to insert Phono Stage MM/MC functionality via the insertion of two boards, one for each channel (dual mono). It also has an optional USB digital input, facilitating a direct connection from a transport or streaming device.
Transparency, timbral neutrality, transient attack, great dynamics yet having the ability of reproducing even the smallest nuances of the musical signal, both at high and low volumes. These characteristics express a lot more than its deliberately compact dimensions would lead you to expect.
The external design of the Norma REVO IPA-140, like many Italian masterpieces, express the synthesis of form & function, technology and aesthetic. As if they were forged by a harmonic dialogue between tense lines and smooth junctions, the shape appears to be relaxed yet at the same time loaded with a strong dynamic charge.
The internal workmanship is extraordinary and highlights a technical refinement that follows the same philosophy. The REVO IPA-140 uses proprietary circuitry, a regulated high-speed power supply, low noise architecture and is built with a careful selection of the best available materials. Norma audio pieces possess a sophistication of sound that is extraordinary at any price, embodying the designer Enrico Rossi’s technical talent and somehow infusing the culture and musical tradition of Cremona.
In audiophile terms, what would be the definition of a ‘giant killer’? Would it perhaps be a high quality product from a lesser known, yet highly respected & established brand that when compared to other-well regarded products costing many multiples more, easily out-performs them in a direct comparison? If this is the gist, the Norma IPA-140 owns that label. Audition and experience why this integrated amplifier has won the hearts of many music lovers around the world.
