  • Nagra HDamp

    Power
    250 W RMS per channel into 8 Ω
    30 W pure class A

    It all started from our customers who could not use Nagra amplifiers, like the acclaimed Nagra MSA, in their bigger systems because they needed more power to accommodate demanding speakers or a very large room. They were frustrated to mix and match Nagra sources, such as the HD DAC, with other brands for amplification.
    Early in the development stage, we realize that we could push the limits of what is possible to achieve in an amplifier, if we allowed ourselves to have a larger chassis. We took inspiration from the world-acclaimed Nagra VPA amplifier and designed elegant tower-shaped monoblocks.
    The power supply goes to extremes to make sure the amplifier is stable and can deliver high power at any time. It is built around a 1600 VA transformer. In Nagra’s own tradition it is followed by a multiple diode stage and a very complex dual PI filter. This allows the amplifier voltage rails to be extremely stable. In addition, the current draw from the HD AMP is not polluted by impulse signals. So the rest of the set-up can perform at its best. The dual Pi filter acts like a protection shield between the HD AMP and the mains.
    Each Nagra HD AMP unit features a bank of 264 mF of custom-made Mundorf condensers. They are the reference in their category and you rarely meet them in this quantity because most manufacturers consider them too expensive. We have chosen them after many hours on the test bench and numerous critical listening sessions.
    The Nagra HD AMP audio amplification stage is relatively simple in its conception; this is in part what makes it so transparent and direct. Actually, each stage has been tuned to reach striking results. The driver stage for instance features numerous decoupling capacitors of different technologies. It has a very low output impedance to make the most of the power MOSFETs that follow.
    Like all its famous predecessors in Nagra range, the HD AMP, uses MOSFET, field effect transistors. They are the closest thing to a valve triode and you can definitely feel its sonic character: direct, fast and musical. The HD AMP has precisely matched clusters of MOSFET, to insure the purest reproduction.

    Event Reports - The Speaker Shack visits HMF Solutions with the Focal Stella Utopia EM Speakers.

    I paid a visit to HMF Solutions who are based in London and specialise in some of the best boutique high end audio products which will make you never want to leave or listen to Stravinsky on anything else but Focal and NAGRA electronics. It was a few hours of musical bliss and for the first time I got to hear what amazing sound NAGRA and Focal Speakers can make together.

    http://speakershack.co.uk/articleResult.php?subject=3&record=1211#.V-ErQ-7veT9.mailto

    The system that Ian the owner of HMF Solutions was demonstrating was a pure reference set up with the new NAGRA Classic amplifiers in bridged mode, meaning the Focal Stella Utopia Speakers were being fed with some serious current from the NAGRA Classic amplifiers. The line stage was equally impressive comprising of the NAGRA Jazz Preamplifier with dedicated PSU to feed clean DC current to the delicate pre-amp stages. Also accompanying the Jazz was the NAGRA HD DAC and CDC Transport which was playing some of John Rutters Requiem. This sounded sublime with great resolution and imaging from the Focal speakers. The high notes just melted away with no stress or strain on the ears but instead was a soothing and satisfying blend of how good Classical music can sound and one of the reasons I love listening to quality high end audio equipment, especially when it is of this calibre.

    The NAGRA Classic Amplifiers had an amazing grip on the Focal speakers with plenty of headroom as Ian adjusted the volume levels, giving a hint of just how much they actually possessed, suffice to say they easily drove the room to very high levels with plenty more power in reserve. The power of these amps in bridged mode was very impressive and for the price they sounded as good as anything else that I have heard before, that includes the likes of Krell, D’Agostino and Audio Research. I love the look of NAGRA kit as they simply ooze quality. With thick aluminium panels they are solid and have such a retro but fresh and up to date modern look about them, I also like the black and white VU meters that they have on each of the amps. Indicating the power levels on both units. This is not something new but distinctly NAGRA in style.

    The Focal Stella Utopia EM Speakers are an extremely menacing looking speaker, but for all the right reasons. They are so well built and look stunning in room and are big, but nowhere near as big as the Grand Utopia speakers that I have also listened to. They lack nothing when it comes to scale though and were firing off a huge sound stage on the end of the NAGRA electronics which seem to be so well mated. My favourite part of the visit to HMF Solutions was when Ian put on some Vinyl, it sounded simply sublime with so much power from the Focal speakers that you could really hear everything off the album. The detail and resolution had me drooling for more. Stravinsky’s Firebird was breath taking on the end of this kit. Every bit of emotion came through in the music which had me glued to my seat.

    NAGRA is a brand that I have been longing to hear and I am so glad that I made the trip up to HMF Solutions as Ian has really done a stupendous job at setting up this intricate but fascinating system. I have had a taste of what the Swiss can do and it is truly magical when in full flow. NAGRA is a brand that I will certainly be revisiting and listening to again, hopefully next time it will be in my room with my set up.

    Reference (Haute fidélité)
    http://www.nagraaudio.com/wp-content/uploads/CLASSIC-AMP_HauteFidélité_2015.pdf

    The Nagra CLASSIC AMP was designed for extremely high quality installations, which require high power while maintaining a perfect musical delivery of the Watts.
    The unit operates in pure class A over a very large power band and beyond in class AB. Each of the output stages is based on tandem MOSFET transistors of exceptional characteristics.

    Generally, assembly of an equivalent output stage requires several pairs of transistors, which is difficult to achieve precisely. The simplicity of the CLASSIC AMP’s design is the key to its musicality.
    The input and driver stages also contribute equally to the overall performance and precision.
    The Nagra CLASSIC AMP is characterised by its stability, irrespective of the loads placed upon it.
    The power circuits drew particular care in the design stage.

    They are based upon an innovative concept: An overdimensioned transformer and a diode bridge are placed upstream of the PFC decoupling stage, used to actively correct the power factor.
    The filtering is achieved with a bank of capacitors, totalling 300 000 μF. This supply concept, which ensures efficient energy transfer, allows immediate reaction on even the most abrupt transients.

    The Nagra CLASSIC AMP is fitted with a traditional Nagra Modulometer on the front panel, showing the power of each output channel.
    An LED is also fitted to indicate saturations, excessive temperature. The amplifier is equipped with balanced and unbalanced inputs and in IN/OUT trigger function. It can be used in a bridged configuration, giving 1x 200 W into 8 Ω, and can also be used in a bi-amplification configuration if desired.
