Естественно конструктив. Но минимелф достаточно большой по размеру.

Вот что прочел у Чарльза Хенсена (Ауре аудио).
Maybe I should listen to them again. About 13 years ago when we were working on the K-1 preamp that uses silver-contact Shallco rotary switches with stepper motor drives, we needed a surface-mount resistor due to space constraints. So we ordered samples of everything we could think of from every major manufacturer. This included Ta-Ni parts, because the Shinko tantalum resistors were supposed to be the really hot thing for through-hole parts.
The test protocol was to put a pair of rhodium plated RCA connectors back-to-back, one male and one female, and put a 10 kohm in series with the hot and a 1 kohm shunted to ground, to create a 20 dB attenuator. This would plug straight into the power amp, and was fed by one of Jocko*s D/A converters using the fixed output (which sounded quite a bit better than the variable output). It was a simple matter to swap out attenuators and pick out the best sounding resistors.
(By the way, this is exactly how we did the listening tests for PRP that resulted in their PR9732 "audio" resistor.)
All of the thick films sucked. They weren*t offensive, but they had no detail, no resolution, and the bass was lumpy and ill defined. All the brands we tried sounded exactly the same.
All of the thin films sucked. They sounded, well, "thin". No body, a lot of extension at the high end, a lot of false detail. I guess a lot of people would like them, but I didn*t think they sounded musical at all.
The winner?? The only SMT resistor worth listening to was the SMT version of the Roederstein through-hole parts. This is no surprise, because it is exactly the same part, but without the leads. It pretty much sounded exactly the same as the Roedersteins, which are still some of the best-sounding resistors around. They are in a MELF package, which is kind of a pain, and they have the steel endcaps, which I still don*t get. How in the world they can sound good with steel endcaps is beyond me.
I listened to some old Wondercaps or something that had steel leads and they were laughably bad. But then again, every tube in the world has steel internal parts. So go figure....
Anyway, back then there wasn*t any difference between the tantalum parts and the nichrome parts. I know that IRC was one of the brands we listened to. I*m beginning to think that the problem is the nickel barrier layer. It*s used on almost all SMT parts. George Cardas swears that it is the worst sounding material known to man and that a layer of that on a connector will ruin the sound quicker than anything.
So I*m still waiting for a thin-film SMT resistor without a nickel barrier layer that doesn*t cost $7 each..
Не надо думать, что все аудиозапчасти это разводка, это очень узколобый и предвзятый взгляд. Понятно, что, к примеру, OPA604 "фор аудио" это мерде, но нестоит огульно охаивать все. Религиозные убеждения (в число которых входит "все аудиозапчасти фуфло"_ это, ясно дело нехорошо, а вот ухопроверенные - очень даже.
