With the support of Shengya Audio, Lego Audio, Beijing Kaifeng Audio, and the majority of audiophiles, the third stop of the "Extreme Sound Good Sound" event on March 9, 2019: The Shengya Audio special event ended successfully!
"Superior Audio, Good Sound" is a series of high-fidelity Hi-End audio system appreciation events organized by the Home Appliances Forum in response to the various deficiencies in the current Beijing audio market, and then combined with many high-end Hi-End manufacturers to prepare for audiophiles in the capital area. The purpose of this activity is to make the best use of high-end audio equipment, but also to let the enthusiasts in Beijing get the best music appreciation fun. To this end, the total value of the audition equipment for each series of activities planned is more than 500,000 yuan, and it has been meticulously debugged at the Beijing Offline Experience Center of the Home Appliance Forum. In each event, the Home Appliance Forum also invites designers or product managers who are most familiar with the products of the manufacturers or general agents to give technical explanations and interactions, so that the enthusiasts present have a deep understanding of the product characteristics and quality.
Preparation before the event: Most of the equipment for this event arrived earlier. Therefore, the editors of the Home Appliance Forum set up the equipment roughly in advance, and conducted an audition to determine the equipment used in the demonstration. At the beginning, the sound source was Shengya CD-1 CD player + Shengya CV-1 tube fully balanced decoding Hi-Fi preamplifier + Shengya PSM-500 post stage*2, and the speaker promoted was the British ATC SCM150TPSL, with exquisite sound , The information is rich, and the sound effect is very gratifying. However, when the editors switched to the flagship preamp CS-6 of Shengya, they immediately felt that the sound took a higher level. So in the end, the editors decided to use Shengya's flagship pre-stage CS-6 as the pre-event stage.
In addition, in the process of constantly matching the pre-amp, the editors also found that both pre-amps support 2-channel balanced simultaneous output, so they immediately decided to use two additional PSM-300T post-amps to bring out the sound of the event. To Zhimei. The PSM-300T rear stage mainly drives the treble and midrange of ATC, while the more powerful PSM-500 rear stage specifically drives the ATC SCM150TPSL woofer unit. It can be said that the ATC SCM150TPSL at this time has been completely conquered by the 4 later stages of Shengya. Whether it is playing symphony or string music, vocals, high school and low frequency speaker units can send and receive freely, with ease.
On Friday, Lego’s President Liang came to the experience center. In addition to the equipment edited and adjusted in the home appliance forum, two pairs of British ATC SCM-7 pianos were promoted by the merger of Shengya A-238 before and after the afternoon event. Painted special edition bookshelf box system. In terms of equipment debugging, Li Gaoliang has always spent a lot of time and effort to debug equipment. Finally, the third stop of the "Extreme Sound Good Sound" event: The demonstration equipment and placement of the Shengya Audio special session are as follows:
Sound source: Shengya CD-1 CD player
pre-amp: Shengya CS-6 fully balanced tube and transistor mixed pre-amplifier, Shengya A-238 combined before and
after the stage: Shengya PSM-500 post-stage *2 Shengya, PSM-300T rear stage*2
speakers: British ATC SCM150TPSL, British ATC SCM-7 piano paint special edition (2 pairs)
Electricity: Canada Torus Power
Wire: German HMS signal cable, power cord, American Kimber Kable speaker cable
Saturday morning , Mr. Wu from Kaifeng Audio, a Beijing distributor of Shengya Audio, brought the Takaoka asr-3 equipment rack to compare with the original Japanese TiGLON equipment rack. After Duolun auditioned different repertoires, the equipment for this event was more suitable for matching with Gaoqiu asr-3 equipment rack. At the same time, the placement of equipment other than speakers was adjusted.
Let's start with the introduction of the sound source: The sound source of this event is mainly a CD player, using Shengya's flagship CD-1 CD player. The appearance of this CD adopts the design of LP vinyl record player. The shock absorber system and servo system are very reliable. At the same time, the large-scale all-aluminum foot-post streamlined chassis and the top-open record warehouse are of advanced design. Balanced audio amplification, using imported electronic tube and FET field effect tube two sets of output. Vacuum tube and transistor hybrid precision high voltage regulated power supply. Philips VAM1250 brushless motor movement. The digital and analog conversion chip adopts two American Burr-Brown company decoding chip PCM1792 (24Bit/192KHz). The analog signal amplification adopts the high-precision, high-speed operational amplifier OPA627, OPA2134 and OPA2604 of Burr-Brown Company. Balanced digital and optical and coaxial digital output. 4 R-shaped transformers supply power.
The preamplifier uses a hybrid preamplifier of Shengya CS-6 fully balanced electron tube and transistor. The core of its amplifying part is a DC combined gallstone hybrid amplifier circuit developed and developed for many years of experience. The dual mono full-balanced amplifier circuit design of the gallstone mixed tone is complete; in order to reduce the dynamic crosstalk interference, each channel uses a power transformer, and a special transformer shielding box is used to eliminate power noise interference. In addition, the CS-6 fully balanced electronic tube and transistor mixed pre-amplifier with eight Russian-made audiophile grade 6922 electronic tubes with gold-plated feet and fully gold-plated tube sockets, the sound performance is significantly better than ordinary products. The tube type A output buffer with up to 30V undistorted output voltage can easily match any post-amplifier. Made in Japan ALPS large quadruple high-precision potentiometer, small channel error, long life, and ensure beautiful sound performance.
Shengya PSM-500 rear stage and Shengya PSM-300T rear stage are the main force of this event, and the appearance and size of the two are very similar. The appearance of both are independent mono A/A and B balanced transmission amplifier structure. The appearance of the whole machine is also large in black, and decorated with a small amount of aluminum metal parts; the front is similar to the blue power watt indicator table. Both the unbalanced signal input terminal and the speaker connection terminal are made of WBT brand made in Germany, and the balanced signal terminal is made of NEUTRIKP brand made in Switzerland. The internal audio signal connection line adopts imported wire, so that the audio signal can be transmitted more ideally.
The difference is that the rear stage of Shengya PSM-500 is currently the flagship product in mass production (the higher-end PSM-600 above is a customized product), and its power supply part is composed of a 1500W toroidal transformer and a 120,000 microfarad audio special electrolytic capacitor. The maximum output of pure Class A is 50W delicate and thick energy. After more than 50W, Shengya PSM-500 rear stage and Shengya PSM-300T rear stage will automatically switch to Class A and B output status. However, when it exceeds 50W, the two will automatically switch to Class A and B output modes. At this time, the rated output power of the rear stage of Shengya PSM-500 under 8Ω impedance can reach up to 500W (1000W under 4Ω impedance); and Shengya The PSM-300T rear stage rated output power at this time is up to 300W (under 8Ω impedance, it doubles to 600W at 4Ω).
Soundya PSM-300T rear stage, as well as the new soundya A-238 combined front and rear stages have to be mentioned. This combination machine is an upgraded version of the gallstone combination machine A-211. In appearance, the two are very similar. But the difference is that Shengya A-238 combines the front and rear stages to increase the power output a lot. At the event site, President Liang used this rear stage to simultaneously promote 2 pairs of British ATC SCM7 piano paint special editions, which was also easy to do
Although British ATC is a supporting role, its excellent voice performance at this event was praised by the guests. The active version of the SCM150ASLT of the ATC Tower series ranks third in the same series, with SCM200 and SCM300ASLT. Compared with SCM200ASLT, the overall quality of SCM150ASLT only uses one woofer. All design materials still maintain the highest level of ATC, and the design materials do not compromise. ATC SCM7 should be the smallest speaker of ATC. ATC speakers have a rule. The number behind its model is the volume of the speaker cabinet. scm7 means: a household monitor speaker with a volume of 7 liters. The special edition of the British ATC SCM7 piano paint was unveiled at this event. Compared with the ordinary British ATC SCM7, the appearance is more fashionable, and the speaker unit and internal components are also upgraded. During the event, don't look at the small speakers, but the sound is excellent and staggering.
