At 2:30 p.m. on January 13, a Perlisten ASR** appreciation event was held in the audiovisual room of Home Theater Technology magazine. The main character is Perlisten**'s S7T Limited Edition floorstanding loudspeaker, ASR Emitter II amplifier. In preparation for the event, all the equipment was in place and debugged the day before. Since I was hosting the event and asked me to share it with the audiophiles**, I started selecting the records that night and also auditioning the pairing. From classic recordings to recent recordings, from pop to classical, vinyl and CD records, the S7T Limited Edition with ASR Emitter II is not an ordinary outstanding. 
The S7T Limited Edition is flanked by carbon fiber
The s7T Limited Edition's foot seat is customized by Isoacoustics in Canada, and there is a shock-absorbing design inside the foot seat to isolate the speaker from the ground
The S7T Limited Edition's terminal blocks are larger and thicker, with a larger, tighter contact area with the speaker wire; The name of the CEO of Perlisten is engraved on the metal nameplate of the S7T Limited Edition to signify the quality certification of the S7T Limited EditionLooks similar, but has been fully updatedI remember 2 years ago,The magazine came to a pairS7T,At that time, it was the first time to listen to S7T,Later, I listened to a full set of Perlisten speakers in the audio-visual room of Foshan dealer Jusheng Audio-Visual Audio,The front main channel speaker isS7T。 I said right then that the sound is really transparent, clean, with clear details, strong texture, and pretty good sound quality. Why should I mention S7T? The reason is simple, the S7T Limited Edition is further optimized from the S7T. You must know that the performance of the S7T itself is already quite good, what else can be improved when it comes to the S7T Limited Edition? What else is there to improve? From the obvious appearance, the S7T Limited Edition has carbon fiber on both sides of the panels, and the four bases of the speaker are custom-made suspension bases from ISO Acoustics, a company specializing in the design of audio shock absorbers. As for the places that cannot be reached from the outside, first of all, the Textreme cone mid-woofer, commonly known as the "checkerboard", has been improved, and the voice coil magnet has been redesigned, so that the linear stroke range has been increased by 20%, which means that the S7T Limeted Edition maintains low distortion at a higher output sound pressure level. The short-circuit ring has also been redesigned to reduce the inductance of the unit. In addition, all units have improved heat dissipation to further improve the power tolerance of the units, and finally the crossovers have been readjusted. Equivalent to S7T, S7T Limited Edition is a comprehensive update. The S7T Limited Edition is a limited edition limited to 50 pairs worldwide! Perlisten strives for excellence in the production of each S7T Limited Edition, all the components on the unit and crossover are precisely matched, with a tolerance of only 1%, and the parameter pairing error of the final product is 05db。And each pair of S7T Limited Edition has a thick manual, which not only introduces the product, but also provides the measured parameters of the product in detail, and is signed by Dan Roemer, CEO of Perlisten. 
The S7T Limited Edition's woofer has been re-optimised to increase the line-stroke range by 20 per cent, while also improving heat dissipation to allow the driver to withstand more power and maintain low distortion at higher sound pressures
One of Perlisten's signature features, DPC Array directivity control, minimizes the negative effects of room acoustics, and the module includes a pure beryllium dome tweeter and two Textreme carbon fibre midrangersPaired with ASR Emitter II Basic amplifierThe German ASR Emitter II Basic power amplifier was selected because the first business owner thought that the sound effect was the most ideal power amplifier after many matchings. There is a prerequisite for the collocation here, that is, the difference between the two should not be too great. The price of the S7T Limited Edition in China is 280,000 RMB, and it also needs to be a good match in terms of matching power amplifiers, and the current price of the Emitter II Basic power amplifier is 2090,000 RMB. One of the features of the EMITTER II Basic amplifier design is that it is divided into three chassis, two of which are equipped with transformers to supply power to the left and right channel amplification lines. In addition to the power amplifier line, the bottom of the chassis is full of filter capacitors, which are close to the power amplifier line. The idea of ASR is to use these capacitors to store the electrical energy transmitted by the transformer and then quickly supply power to the amplifier line. Thanks to the exaggerated power supply design, the ASR Emitter II Basic amplifier has no worries about driving force at all. In terms of output power, most HiFi amplifiers have a nominal output power of 8 ohm load and 4 ohm load output high power, but rarely dare to standard the output power of 2 ohm load. But the Emitter II Basic is different, its output power per channel is 250W (8 ohms), 450W (4 ohms), and even the output power is 800W when the load is 2 ohms, and the power amplifier that can stabilize the output power at 2 ohms load is really not simple! However, a detailed review of the ASR Emitter II Basic amplifier will be left for the next issue. 
Each pair of S7T Limited Edition comes with a thick manual, which also lists the measured parameters of the speaker in detail, and the manual is also signed by PerlistenCEO Dan Roemer. Listen to vinyl records, it works great! As for the ** end, I was very lucky this time, and the ** new sound of the ASR amplifier also provided me with a vinyl turntable and CD player. In my record collection, there is a part of ** that I have both CD and vinyl versions. I listened to it from a vinyl record of Sir Boulter's Elgar Symphony No. 1 released by EMI in a drawer**, and I also have a CD version of it, and it is still a Black Angel front version CD. Listening to the sound system, the difference between the two is really huge. In terms of timbre differences, the vinyl version has a stronger texture, a more straightforward timbre, and it will look mellow when listening to CDs, and the amount of mid-bass will be fuller, and the timbre will be more bright. Although the vinyl version of this recording is not as quiet as the background of the CD version, I personally like the sound coming out of the vinyl disc from the perspective of listening to the sound. Through the replay of the S7T Limited Edition, the sound density when the orchestra plays in unison, as well as the openness, height and depth of the sound field, the vinyl version is very good, it can be described as easy to show, it can be described as self-indulgent and unrestrained, this effect is the "off-box feeling" pursued by audiophiles, especially the undercurrent of the bass at the beginning of the fourth movement, the sound of the S7T Limited Edition replay is very full and very solid, The scale of the soundstage is huge. There is also the recently released "Piano Memories"** which is also released on CD and vinyl at the same time. The strings used in the performance are made of silk, and the timbre is relatively restrained and gentle. After comparing the two, the vinyl version of the sound feels a little better texture, the sound image is more solid, and there is a sense of 3D, while the CD record sounds relatively gentle and the sound is smoother. Anita Mui's eponymous "Anita Mui" (aka "The Year of Water") is also my favorite**, released in 1985. The whole album is a slow song, use today's audio equipment to re-listen to this classic**, S7T Limited Edition's high resolution and high transparency, it is easy to present the details inside the record, which allows me to hear the characteristics of the post-production of the record, which can be said to be some defects, or a technique. Especially the title song "Like a Year of Water", the later mixing of the vocals will seem a little mixed, not so clear, but in exchange for a kind of artistic conception, there is also a warm, rich, comfortable feeling, and Anita Mui's singing is also very "tasteful", it is simply wonderful, but real. Best-in-class resolution and transparency, high-quality bassIn the previous chapter, I said that I like the classical ** recorded by EMI very much, and I like its timbre orientation very much. EMI has a series called Artist Profile, which includes recordings of famous artists. I particularly like one of Witold Malcuzynskid's 1959 recordings of Chopin's Waltz, which is very majestic, emphasizing the contrast between strength and weakness, which is completely different from Rubinstein's dragonfly style. About this**,I have had a profound experience twice,The first time was on the Focal Utopia headphones,The second time is this S7T Limited Edition speaker。 When the CD player starts, the back noise of the old recording is particularly clear, and when the piano sounds, the piano sound is warm, full, and powerful, and you can feel the finger force quite fiercely. And the S7T Limited Edition's sound resolution is really good, and although the recording itself comes with back noise, I can still hear the faint spatial details in the recording. In addition, the bass quality of the S7T Limited Edition is very high, the bass is full, and the piano table is very grandiose and solid. But when I switched to Marta Deyanova's Rachmanilov Piano Sonata No. 2 (recorded in 1979) at Nimbus Records, the vinyl record used Direct to Disc Recording, what audiophiles call a direct-engraved record. After the microphone collects the sound, it enters the mixer and mixes it into two tracks, and then directly hands it over to the engraving machine to engrave the master disk, which belongs to audiophile-level positioning recording. The effect of S7T Limited Edition** can be described as amazing, the texture of the piano is very real, the sound of piano resonance is recorded quite well, the bass is magnificent, the whole piano is very clear, and it is realistically presented in front of you, the overtones are abundant, and the above recording** is not a level at all, after all, there is a difference of 20 years between the two recordings, and the technical level is not a level. Fast transients, precise positioningI continued to listen and found the "Dachang Disc" from the record cabinet, which was a gold disc re-released in the 90s, which belonged to the fever recording. I especially like the eighth part of the "coco jam", which is divided into three parts, the first part makes you feel comfortable, the second part starts to pick up the tempo, and the third part is full of enthusiasm. I know an audiophile who uses million-dollar speakers and he has a disc like this. He once said that if the acoustics are in place, you can hear very clear positioning, as well as shimmering timbre. Listening to the S7T Limited Edition this time, it seems that I can appreciate his description of this record. When I sat on the emperor's seat and listened to this "coco jam", the positioning of all the instruments was very clear, very precise in front of me, the texture of the instruments was very strong, the sense of scene was full, it could be called high definition, and the sound was clean and clean, and the transients were fast. The timbre of the instrument is even more vivid, gorgeous, and shiny, perhaps this is the sparkling tone described by my friend.
Summary. The Perliten S7T Limited Edition paired with the ASR Emitter II Basic is one of the best I've ever heard of a Perliten loudspeaker. In fact, the design of the Perliten Signature series speakers itself is very good, as long as the amplifier is matched, the sound effect must be a blockbuster, you can feel the real transparency, the real clean, the real high-definition sound, the sharp dynamic contrast, and the accurate restoration of the details inside the record. In addition, I know an enthusiast who is also a new user of Perliten S7T Limited Edition, and is trying different power amplifier combinations, and one day when he is ready, I hope to pay a visit to my home, maybe the S7T Limited Edition will perform differently at that time.
