The company iBasso does not stop on achieved results and continues to produce one good amplifier and, judging by the news, went in the course of non-trivial solutions. While the option of microarray NuTube is in development, let's talk about the modules with discrete amplifiers, the received indexes AMP7 and AMP8.
Inside of both amps are similar, use of proprietary development on the basis of transistors with low saturation voltage allowing not only to achieve a good voltage swing, but a decent recoil current. According to the developers, the transistors are sorted by hand in pairs for best performance. AMP7 uses a normal 3.5 mm connector, and AMP8 — balanced Pentaconn, different source and their characteristics, being balanced model «eight» offers greater voltage swing. So in theory AMP8 in the pros a better separation of channels and the ratio signal/noise, but, in fact, both modules these parameters still lie outside the discernible range of human hearing. Despite the differences in their designs, the cost of the modules does not differ and is about 15000 rubles.
Boxes have remained unchanged: white cardboard, grey paper strip around. Located inside the amplifier module, screwdriver (I have quite a collection), spare cogs, and warranty card.
The installation is very simple: weaken the cogs (completely remove them is not necessary), remove the module, put a new, gently tighten the screws back. To do this, of course, very desirable when you turn off the player.
With these amps iBasso DX200 time in my measurements was 6 hours 55 minutes AMP7 and 6 hours and 25 minutes with AMP8.the
Most of the tests of these modules I spent with iBasso DX200, first to discover their potential, and, secondly, of all the modules DX150 I subjectively like it AMP6, have this couple some special synergy.
The overall presentation of both amps is somewhat «analogvalue» in color, they are slightly smooth out the harshness, but it adds a bit of emotion, giving the music drive and drivepast. The difference between 7 and 8 is not great, in fact, we can safely say that it is power, and if headphones sensitive, the differences when comparing at the same volume to hear will not work. Naturally, the same volume should be set using the sound level meter, not the numbers on the player screen.
So both modules are different in a darker color relative to AMP1, they have a slightly lower noise level, which also contributes to the impression of their sound.
Discrete modules add a bit of bass depth and weight, which in turn gives some boost to «monumental» sound. Given this increase due to a small reduction in resolution but the bass is still detailed. As compared to AMP1 slightly increases attack speed by NCH.
MIDs get a small increase to the width of the imaginary scenes, and a bonus in the form of emphasis of emotions. Slightly reduced emphasis on microcontrast, but this reduces the criticality of the player to the quality of the material that stock DX200 were often a problem. In General, the sound is slightly shifted from neutrality to a more «taste» flow, but it sounds very vovlekayut.
In General, not the company iBasso cares about its customers does not facilitate their a difficult choice: each module of the amplifiers is good, and choose the «best» almost unbelievable, but «seven» «eight», perhaps, as much as deserve this title. At least as long as the company has not released something new, and they have obviously prepared.
