Pros
- Good acoustics in general (such), I sometimes turn on this retro system. Here I would like to note what distinguishes them from other speakers. The strengths of the NS-6490 include a very wide smooth sound, good stereoscopicity, and an excellent midrange. A sound with some emphasis on the upper and middle frequencies, giving this speaker the brightness of reproduction at these frequencies. In terms of the breadth of sound, in the construction of the scene, they can really compete with the speakers at times more expensive, this is facilitated by the large speaker size for bookshelf speakers and three-band. Despite the laminated coating of the woofer, the characteristic soft features of the "cellulose" sound are clearly audible in the sound, the woofers are very soft. both components sound musically flowing, not overloaded with unnecessary details, booming bass, with some pastel tones, a veil. The harshness of the sound in some reviews is probably due to the unsuccessful selection of the amplifier / acoustics bundle, there is some tendency to harsh sound in the treble and upper midrange, the NS-6490 tweeter is plastic (not silk, but not metal either) They look very good, they are very beautifully painted. Vinyl film finishing is more expensive, but it is immediately clear that this is a film and in general the difference is small, although the film is more beautiful, however, both there and there are budgets, but the main thing is sound, appearance is secondary. Now I would buy them again if I was looking for acoustics up to 10 thousand. ~~~ Small and deep upgrades are available, but if you take the factory-made speakers, then the acoustics are 5-6 thousand. almost all have second-order crossovers of one quality or another, hung on the best speakers, it is doubtful that even after a deep upgrade, the NS-6490 will beat the factory speakers, which are 6 thousand more expensive, i. E. around 15 thousand.
Cons
- It is quite reasonable to pay attention to other properties of the product. Bass for this money is generally acceptable, but does not match the appearance of the speaker with a circle with a diameter of 200mm. The convexity of the midrange in general never tired me, although I also like the powerful bass, sometimes quite powerful, which is not here. A powerful bass is when, at a volume slightly higher than the usual voice, crystal in the cabinets begins to ring, and if it is louder, under furniture doors, etc. you need to put linings so that they don’t clap, but here the 6490 is more likely to fall apart :) However, the main thing is that the basses should be harmonious. The convexity of the midrange and treble is present, however, in tests with soft Marantz, Panasonic, moderately soft Sony, medium Philips and Denon, I did not feel uncomfortable sound, however, everything is of course subjective. Tests with Denon showed that the potential of the NS-6490 in terms of crystallinity and transparency was exhausted by 75%, and the strong-bass Philips did not show the bass it was capable of, although, in general, relatively good bass. It should be noted that budget amplifiers and decent stereos are able to produce much better sound than paired with the NS-6490, my stereos with acoustics for $ 300-500 almost always easily beat Hi-Fi stereo CD receivers in tests, which were paired with the NS-6490 ($150), connecting the NS-6490 to these budget Hi-Fi amplifiers gave a smaller, or rather negligible increase in sound quality than connecting more expensive acoustics to the Amazon. The NS-6490 did not reveal the capabilities of these amplifiers. Hi-Fi amplifiers with speakers for $ 300-500 surpass the NS-6490 in sound by one or two orders of magnitude, practically regardless of what the NS-6490 works with, the quality of a built-in system is always limited by the quality of the "weakest" link in it . The cost of acoustics is fully justified, it has been serving for decades, but of course, be sure to listen for yourself. If you now turn on the speakers more expensive, everything will immediately become clear and the NS-6490 will modestly listen to them on the sidelines. However, when the NS-6490 is played, there are no negative emotions, only positive ones.
