Rotel RSX-1550 AV Receiver

He also looks so beautiful: by Rotel’s new, equipped with HD decoder multicultural RSX 1550 (1900 euros) expected stereoplay not only Jet swagger, but above all a possible draw sound.

At first glance like Rotel’s new RSX 1550 with its smug brushed aluminium front and the send metal lenses mistake surely each. But then the 1900 euro receiver puts the greed chasms that are intoxicated on overflowing Internet feature lists in depression.

So, as the question answered after Dolby Headphone so that even no headphone jack is on the RSX. A clear nyet speaks the Rotel as well to iPod and network activities as well as to a measuring automatic and Equalizer airs out. By the buttoned to AVler to all this offers only five stages of installing in addition to fare boxes Terminal, probably finally throws bewilderment.

Not everywhere! Five decent amplifier might seem more enticing than seven lousy music of loving realists. Especially since they may be only four use described for it in the previous month – HD-Quadro. After a Zusatzamps for the front stereo channels of the Rotel allots to – if need be – the now other amps still surround back speakers. He rouses himself also with Pro Logic IIx and an in-house “XS” function to seven-channel extensions.

In any case the RSX 1550 digital data transforms – whether they come from the HD contact surround processor or directly connected sources – with four fine Burr-Brown-stereo converters of type DSD 1791 to analog signals.

After the volume control, which also takes the Rotel not with a large stone, but with total four individual ICs, the tones flocking to then more expensive predecessor of RSX 1058 (8/07) a vast amplifier board as already on the HD-decoder loose, still 100 euro. There, the components must until down to the core, 15-amps capable end transistor couple by fell (2 SA 1368 / 2SC 3519) do not occur on the feet. Moreover they come out again without fan forced ventilation.

Dozens of smaller storage capacitors show that there is shortage of any corner on power supply, a beautiful train can be found in the Hauptelkos. The capacity of 2 x 15_000 may micro Farad as typical class. With 80 volt electric strength, the two supply bottles to the actually pending 50 volts but keep a unusually high margin of safety.

Even more rare in surround receivers: with two front rows of buttons, which allow direct frequency selection, among other things, the RSX 1550 indicates that radio is still very close to the heart. In fact sounded stronger FM stations – clean, down with Schmacke and above get out beaming – hardly worse than about the tried and true comparison receiver RD from Denon TU 1500.

The good impression deepened during CD playback. Also the newcomer with ur substantial, incredibly pithy basses and super rich and vivid votes of less after an AVler as after a rock-solid stereo integrated amplifier sounded like already the RS 1058. While the oldie proved to be a bit no-frills and natural which 1550 an infinitesimal in the direction of cuddly and jazzed up beautifully coloring what but still long could not avoid, that also the new Rotel got fantastic 42 stereo points.

In multichannel, the medal turned around anyway. At the traditional surround the RSX acted 1550 more empathetic, more finely. He developed Dolby Digital titles from “one of these nights” (in- acoustics-DVD) from the percussions-lights and the guitars Geflirre 1058 duller seemed considerably more flair and splendor – while the RSX from Al Di Meolas.

Also old DTS benefits from the new, stronger data decoder electronics. For the bass so as when the RSX rumoring 1058 after heart desire, without losing the style in the least, were allowed to the heights for the 1550 appeared fresh and bare and yet absolutely free of hardness.

So, the 1900 euro receiver at the classic surround seized 49 points and so for the stars. It was still big performance with the new Blu-ray noble audio Dolby True HD and DTS HD. In contrast to his predecessor, who could use this stream directly, but only PCM data word derivatives thereof, the RSX 1550 joined with HDMI 1.3 inputs and HD decoder now without this handicap.

So before life sparkles and so confidently, that he snubbed not only his matter ancestors, but even the AVR 4308 from Denon, hence the in the new discipline of HD best sounding AV receiver, the stereoplay until now knew. On Blu-ray-pop sensation managed the Denon with more bass bang and some other prospects to fight back, to jazz and classical music the Rotel led approach but clearly better: even closer to the gleaming varnish wooden body of the violin, is still closer to the Cascades of light bebederder piano finger runs, still closer to trembling lips of a singer.

So the RSX 1550 brings little dowry, but fulfilling.

With the help of the Genesis Faroudja IC FLI 2300, the video conversion succeeds pretty neat the RSX 1550.

He contends the small target flaws in the color vector diagram prima video frequency course, therefore high resolution.

Also in the conversion of half full line number considering the movement (de-interlacing), there was nothing to complain about Radiant, almost ruckel – and seam-free images.

Measured values

Measured at the pre outs, the clanking history chart shows a typical highendiges picture with evenly rising to higher level k2 (dominant) and k3 (below). After the connection with the Thorens TEM 3200 reference Mono blocks, it sounded in fact devastatingly.
