De vanzare o super rara pereche de boxe vintage japoneze de exceptie, Victor SX-900, aduse personal din Japonia anul trecut si care mi-au servit drept boxe principale de auditie aproape 1 an.
Acestea sunt rivalul cel mai de succes creat de Victor/JVC la aparitia faimoaselor Yamaha NS-2000.
Toate difuzoarele au magneti ALNICO, care contribuie la un sunet cristalin dar totodata "sweet", nu sunt obositoare la ascultat indelungat precum Yamaha care au tweetere si medii din beriliu.
As spune ca pentru genuri precum jazz, clasica, instrumente precum chitara sau pian sau cu vocal in prim plan sunt niste boxe absolut fantastice.

Alti useri care au avut si ocazia sa le compare direct cu NS-2000 au exprimat opinii in aceeasi directie :

"es I received the Victor SX 900. My god the sound is incredible. I feel they have a more enjoyable sound than the Yamaha NS 2000's. A bigger sound.Right there with the band sound.Tight bass. really good quality bass and lots of it, clarity, Lots of detail and an incredible sound stage. Really smooth flowing sound. I'm blown away.They have such a nice sound that you could listen to them for hours without fatigue. I have a pair of Tannoy DC10 and they are worth over $15,000 and they hold there own against them easily. Guys if you can get a pair do so they are well worth it. They bet my highest expectations.

Pretul la lansare pe bucata a fost de 220.000 yeni in 1988, vs 228.000 yeni la Yamaha NS-2000 in 1982.
Ca sa ne facem o idee fata de produse care au mai ajuns pe piata europeana, acest pret e dublu fata de monitoarele Yamaha NS-1000M care fusesera lansate la cca 108.000 yeni pe bucata.

In stare foarte buna estetic si functional, dupa cca 35 ani vedeti si pozele si video demo atasate.
Suspensiile difului de bass nu necesita inlocuire la acest model fiind din textil impregant cu cauciuc special, pe viata.

A 3-way speaker system with the same design philosophy as the SX-1000.
Newly developed link type alnico magnetic circuit is adopted in all units.
With the excellent magnetic characteristics of Alnico as it is, the back pressure in the magnetic circuit is efficiently removed by making it a ring type.

The mid-range is equipped with a 6.5 cm domed squaker, and the high-range is equipped with a 3 cm domed tweeter.
The diaphragm of these units is made of Victor's unique fine diamond ceramic material, which realizes high start-up characteristics.
The network section is divided into three sections to eliminate sound quality degradation due to mutual interference.
The front baffle is made of 38 mm thick maple wood. It is hard and has an appropriate internal loss to improve the clarity of sound. In addition, the G-line unit using Victor's unique sound intensity method realizes a rich sound field.
The exterior has a 6-sided wood finish.
The input terminal is compatible with bi-wiring and bi-amplifier.
Comes with a special stand.
