How much tube sound inside hybrid amplifiers such as the MAGNAT MA 800? And most importantly: what kind of tube sound? HiFi fans write to the archaic components namely very different, even opposing some of the qualities.

HiFi fans write to the archaic components namely very different, even opposing some of the qualities. Some expect an acoustic security blanket to protect against the hardening of liebloser digital productions and insist on the traditional image of the soft, warm tube sound. Others Revere a more modern sound ideal and use tubes, to achieve that rare blend of speed and complete freedom of the grain, have coined for the Anglo-Saxon high-Ender the beautiful word “liquidity”.
Metrological point of view the amps of both schools often hardly distinguish what invalidated also the accusation, tube amplifiers handle generally simple effect devices. Their designers use only the opportunity to shape the last rest of character every Hi-Fi has inevitably, clean and consistent after their respective performances. With ERG feats, that allow to understand in each plant.
A particularly convenient entry into the hybrid world marks still quite new in the amplifier compartment loudspeaker manufacturer MAGNAT. The company has fined their boxes developers to free usage, nor did she leave the undignified way, a pure acquisition product with its own name label. The MA 800 is, as already the amazing, fully stocked tube RV-1 (AUDIO 2/09), a genuine, stand-alone product.
And a pretty delicious on top of that: the construction of the MA-800 follows consistently the audiophile teaching. There are encapsulated relays for the input selection, long-life ALPS potentiometers and an IC-free pathway up in the amp consisting of selected individual transistors. Chips can be found only in the Phonoteil, where they stand out but by no means negative: it’s expensive, low-noise operational amplifiers, which make the MA-800 an of a few fully-MC grade integrated amplifier. The close tolerance components reveal the work of a phono convict as identified in the Publisher’s own TESTfactory, Board-straight frequency responses and practice reasonable connection values – MAGNAT here has actually the services of the German Developer bedrock Walter Fuchs (SAC) claim.
The wiring of the tubes in the refined “shunt regulated push pull” procedure, however, shows parallels to the big brother RV-1. Like in this, the two Russian ECC82 double triode form an extremely linear and output low impedance preamplifier in the SRPP arrangement. Instead of power tubes these works to a pair of bipolar transistors of declined per channel in the MA-800 but, that draw their power from their own transformer secondary windings and rectifiers.
The toroidal core transformer of the MAGNAT is not quite as powerful as the more expensive candidate, but is even ahead of MA-800 when it comes to facilities: the mentioned Phonozweig along with double connectors that allow even switching between two connected at the same time players, the balance control (if also not motorized), headphone output and Mini Jack input on the front panel – such a meaningful luxury you are looking for on many other amps in vain.
Though other tube-hybrid conjure up a large, but artificial Western on the stage or vice versa are lost in quiet, intellectual way in tonal depth, remains the genre of British aristocratic romance that plays – castle-like estate with large parks, and usually is not running on the big screens for the Tycoon. Absolutely clean, elegant and balanced, only their intense presence enforce attention missing the MA-800 to the class of the two more expensive hybrids. Where a staging ever, it leaves at a subtle hint, instead always fully play out every smallest movement, has also their charms and permission.
At a high level the whole comparison took place, showed the cross check with the superb, gripping vivid, the magnate of however superior Naim NAIT XS (105 points, 2/09). Unison and Vincent could easily compete each in his way – that was in both cases but based on advantages in power and bass – with the flat British transistor.
