Description Stax headphone amplifier DAC SRM-323S w/box USED Excellent[Condition]USED:ExcellentOperation confirmedThe exterior and interior were in very beautiful condition. STAX SRM-323S All semiconductor/intermediate model Higher model/same output TR as 727A Tradition = class A operation/balanced amplification/DC amplifier/non-magnetic chassis. This is a model that has undergone improvements since the previous model = SRM-323A, and has become even more mature. In terms of specifications, amplification: 323A = 54dB (500x) ? 323S = 60dB (1000x) Input level: 323A = 200mV ? 323S = 100mV Power consumption: 323A = 29W ? 323S = 30W Although there is not much difference in appearance, The volume knob has been changed to black, and the color of the bonnet has become more similar to silver. By the way, the successor of this model, SRM-353X ? Current product / SRM-400S, is a model equipped with an XLR terminal, but for those who mainly use his RCA cable (pin cable), this model is not suitable. I feel that the machine is sufficient. Comes with original box/genuine power cable/instruction manual (original).More than 50 years have passed since Stax released the SR-1, his first condenser ear speaker. And its been nearly 40 years since we started liking STAX ear speakers. I own many models, including the flagship SR-009 at the time, and have collected them as a hobby. I enjoy using a variety of ear speakers, replacing them depending on my mood that day. Stax capacitor molds require precision in the micron range and must be manufactured with extreme care, so most of the manufacturing process is still done by hand by skilled craftsmen, which is in a sense inefficient. It is made using a method. It continues to be a unique presence that represents the true essence of Made in Japan, which unfortunately is being lost in modern Japan. We are a manufacturer with a long history and tradition, which has continued to refine its technology and has maintained its identity for decades. STAXs condenser-type ear speakers are (almost) in a league of their own when it comes to electrostatic types. They have established a worldwide reputation, and their extremely clear and pure sound is colorless, transparent, and full of moisture. It is characterized by a bright, clean, beautiful and elegant sound, with excellent sound clarity and clarity, excellent resolution, and an exhilarating taste that does not make you tired to listen to.This is STAX! One of his characteristics is that he has excellent spatial expressiveness, and the sound field is very wide.From experience, I am acutely aware that the driver amplifier that is combined with the ear speaker is an extremely important factor when it comes to producing sound from ear speakers. Ever since the long-awaited dreadnought driver SRM-T8000 (654,500 yen) was introduced in 2017, there has been a feeling of pressure to rebuild the lineup, but just the other day, each driver amplifier has been completely redesigned, and the price has greatly improved. [SRM-700T=327,800 yen//SRM-700S=327,800 yen//SRM-500T=132,000 yen//SRM-400S=121,000 yen] [SRM-007tA?700T//SRM-727A?700S//SRM-006tA ?500T//SRM-353X ? Model change to 400S] Personally, I felt that although it was a full model change, the circuit configuration inherited the previous contents, reflecting the large cost increase. Speaking of which, I was a little disappointed as I had high expectations.[SRM-323S] STAX SRM-323S All-semiconductor/intermediate model Higher model/same output as 727A Tradition = Class A operation/balanced amplification/DC amplifier/non-magnetic chassis. It has been completely redesigned from its predecessor, the SRM-313. I think its safe to say that everything from the circuit board to the parts layout is completely different. The current model is SRM-400S = 121,000 yen, so if it is a middle-class driver amplifier and the SRM-400S does not have an XLR terminal, but if you can get by with an RCA terminal, this model may be sufficient. think. This is a second-grade all-semiconductor driver amplifier in the lineup, and although it is an intermediate stationary model, it has a solid discrete circuit configuration. All stages are directly connected/Class A operation/balanced amplification/DC amplifier, and the contents are firmly inherited from the higher-end model.Adopts plenty of low Cob high voltage transistors such as 2SA1968 and 2SC5466.What is noteworthy is that the final stage output transistor uses the same transistor as the top-of-the-line model at the time, the SRM-727A. As expected, the power supply section and the grade of each part are not as good, but it has been carefully designed and the parts are neatly laid out on a high-quality glass epoxy printed board. The chassis is made of non-magnetic aluminum alloy to avoid the negative effects of magnetostriction.The large power transformer is insulated and mounted from the chassis for vibration resistance. The volume is also a custom-made detent type, and it has been carefully constructed without cutting corners, so I think this is a driver amp with excellent cost performance. Since this amplifier is designed with sound quality in mind and operates in class A mode, it generates quite a bit of heat. I took a picture of the inside of the amplifier when I cleaned it with air blow. Please make yourself useful.There are some scratches and scuffs due to use, but I feel that there is no major damage that stands out. Please refer to the pictures for more details.
