Harman/Kardon AVR 255

Harman/Kardon has obviously found back to old strength. After several rather nondescript series Americans with the AVR 255 claim to a leadership position again clear.

You can tell on the weight: 14 kg are unusually solid for a 600-euro receiver. The AVR 255 owes a massive power transformer, the copper coils that provide lush power reserves for the amplifiers on classical way supported by also generously dimensioned filter capacitors, its weight in the first place. The latter are tried and true recipe with solid single transistors – 14 in number, because all candidates offers a complete seven-channel power amplifier of Harman.

The Harman scores not only with two, switchable, and only when you need a soft – and ausdimmender dot matrix calligraphy. On the screen he sets a such splendid menu of the current movie with adjustable transparency and full HD resolution, that you think it came from a Blu-ray disc. This interface in different languages is adjustable and very helpful; about if it shows photos of the respective Sockets in the allocation of connections.

The noble GUI in an expensive “chip of Torino” is generated by Faroudja, who remains unbeaten in the conversion of analogue video signals to HDMI in this comparison: the images inflated on HD (up to 1080 p) are sharp, yet in quiet, and remain largely free of undesirable education of levels of and frayed edges also with difficult DVDs. Occurring color, brightness, contrast plus various filters, for example MPEG noise and composite video “CrossColour”-fringing, can be set here upon request for each input individually.

Even on already via HDMI incoming material Torino is the 255 his – a special feature, which is occasionally, valuable in combination with skalieren technically been set-top boxes, has however also a small disadvantage: the Faroudja chip remains in the HDMI signal path even if the image-tuning is set to “Off”. Purists would be at least for the Blu-ray disc, when there is usually nothing to improve, want a real workaround.

As a music and film buffs, the AUDIO testers are thrilled by the new HD sound formats even if they complicate the testing: now always have a passage with HD stands next to the listening tests in stereo and standard surround on the program.

From one type to the other can’t rule it in, how this test also showed very clearly: played a DVD-player Dolby Digital or DTS, gambling on Harman at the top was very large and voluminous with thundering authority. The Marantz seemed strikingly clean, fine and left open, the drummer, but a small little zaghafter strike and was not quite the wealth and the size of the Harman sound – he seemed to represent the music something, when in fact she is simple.

After switching to the Blu-ray disc, more precisely: to the splendid new recording of Wagner’s “Walküre” (Berlin Philharmonic Orchestra, Simon Rattle, DTS-HD Master), that the colleague Ruhnke had just unpacked, passed the Marantz effortlessly on the Harman at the top of the test field – and at the same time the entire price range. The Harman ended up placed in votes with his acting angularity and almost two in addition to the thick and creamy, but somewhat to very simplistic Kenwood exaggerated blaring brass only ranked.

The receiver with feigned to analog stereo sound – the Icelandic composer Sigurd Islandsmoen’s Requiem played the third match (Kristiansand Symphony Orchestra on 2 L; 96/24-download on www.2l.musiconline.no). The ranking was the result with HD sound: very clean, elegant and harmoniously the Marantz, dry and introverted of the Panasonic. In between were the silky soft Kenwood and the solid hearty Harman as a very ordinary stereo performer.
