AV-receiver Luxman LR-7500

The company Luxman, recognized for high-quality CD players and dual amplifiers, recently came to the market with AV receivers high price category. It is therefore not surprising that the model LR7500, being the most expensive among the applicants, in the first line of devices of firm occupies an intermediate position. There are all the trappings of belonging to the class of "High End" - noble forms, aristocratic the simplicity of the design of the front panel, and also... very little information about the hardware. In short, to understand what are the objective reasons for such high rates of staff, is not easy. In particular, its connection possibilities is quite moderate. HDMI is missing, you can manage only analog video signals (up to a component).

The most modes surround should be called standard - except Dolby Headphones, very useful when listening to multichannel soundtracks through the headphones. An interesting feature is a few extra ideas related to changes in the sound of the panorama. Using a pair of settings you can gently stretch centre, directing some information from him in the front and deepen the rear, achieving more tangible "presence effect". Useful and can enter a delay between video and audio (useful for working with plasma screen). Auto-tuning is not that the device for the money today is obvious disadvantage.

The OSD menu is well thought out, which partly compensates for the absence of the system auto configure. However, to install the receiver manually - the process is quite long, because for each source the entire range of adjustment is memorized separately. Developers of remote traditionally put at the forefront of the design, so we recommend to replace the "lazy" some universal remote from experienced manufacturer. This is especially true for fans of projectors - the inscription over many equal keys with little light indistinguishable.

Best receiver showed itself when playing a dual record mode c is disabled voices. Certain problems connected, apparently, with the power supply prevented him from Shine to act in theater roles.

When declared 95 W this receiver was the only one whose measured at THD 0.7% of power not only surpassed, but was much lower than the stated - 68 watts per channel. It makes recommend to him, first of all, bookshelf speakers. Damping factor too small (57%), therefore, should be carefully selected speakers to the receiver. The choice is complicated by the fact that the receiver only works with speakers impedance of 8 Ohms. AFC it behaves strangely on both borders of the spectrum - in the lower part of it irregular, and heaped up at the top (for stereo use the Direct mode, and flow Dolby Digital/DTS pass through the "number"). Built-in decoders can not be called quality - channel separation 49±5 dB for DD and 53 + / - 1dB for DTS yield even own analog input (53 + 2 dB. - acceptable rate, so fans of the SACD/DVD-A will not be disappointed). Ratio signal/noise tuner is only 59 dB, but its sensitivity is the highest in the test (0,9 MACs).
