We started selling Jasmine Jasmine audio from Chinese audio brand in October.
Jasmine Audio is an award-winning pure audio brand established in China in 2001 by avid audio enthusiasts. The detailed components are carefully assembled by hand by experienced and qualified engineers. It is an official brand introduction (abbreviation), but since it is actually very well made,Bakoon ProductsI would like to introduce with the great cooperation of Mr. Nagai.
From Jasmine Audio, we are developing cartridges to turntables and phono equalizers for record viewing, but turntables are also belt drives only. The photo is T-D200MK2. Double arm support. It is very easy to make. (of course)
Bakoon ProductsThe jasmine products that I gave to are below.

About Belt Drive Turntable
We have a report on the setup TT-D200MK2 the turntable of the belt drive.
The 8kg platter weighs is floating with a powerful magnet to make it work very smooth.
But,
Because the magnet is powerful and does not sink, the stabilizer of about 1 km is temporarily resolved. 。
Following Jasmine's instructions, the bearing hole was cleaned with oil and oil was injected to eliminate the phenomenon. If you just put too much oil in, it will overflow for a while, so be careful. 。
This turntable was the last item in the manufacturer's inventory, and for some reason it was not packed in a dedicated case, and I think that it was a little influenced that I somehow filled up and sent it. In the future, I think that this problem will not occur if it becomes packing in a dedicated package because it seems that it was a symptom that is not past the place that actually inquired to the manufacturer.
The actual product is very beautiful. The turntable is compatible with double arms, but in the second, an optional protruding pedestal is required, and a separate pedestal for the tone arm should be much easier to set up. (Nagai's struggles later)
Now, after the problem is resolvedBakoon ProductsIt seems that it was a performance to go up the oblique of Mr. Nagai's prediction (happy lol), and it was a very high evaluation that this price is not available in Japan first with this performance!!
Nagai-san pointed out that the points of caution and correction should be corrected directly by the Jasmine Audio staff. Jasmine responds very quickly to problems, so I feel high consciousness.
Nagai-san reiterated his impressions of the past two months of .
I think the performance as a turntable is great. The platter floats 8mm with magnets installed around the axis. I think it is the same principle as the magnephroat that Tiac used to commercialize, but I think that it greatly contributes to smooth rotation and vibration prevention. However, there was a problem that the individual I used had a resonance with the magnefloat and belt drive, and an upper and lower vibration occurred during regeneration, but when the oil was injected into the bearing, it did not vibrate. Since the platter is floating with a magnet, if you put a heavy stabilizer, the platter will sink and the height of the arm will change. In addition, the record is supported by 6 points on the platter, and this support floats from the platter a little, so the phenomenon that the record goes against the opposite occurs when the stabilizer is put on. In this product, you should not use stabilizers or use light ones. The arm is equipped with two arms: the conventional arm and the company's linear tracking arm. The conventional tone arm attachment comes with a dedicated base, and the pipe-based arm of the same diameter as the company's arm is installed intact. Otherwise, you need to make your own mounting base. The base of the turntable seems to be a laminate of aluminum. It has enough weight and looks good. The base is supported by three bolts on the rubber foot, which are screwed into the bottom and adjusted the height. Rubber feet are hard like ordinary rubber, so vibration absorption is not done here. Walking on the floor will cause needles to fly and noise. However, it seems that the howling does not occur because the platter is floating with a magnet. The motor is 33 Although it is 2 speeds of 1/3 and 45 rotations, the rotation speed can be increased to 78 rotations even with a wide variable range of 33 revolutions. A stroboscope is required to adjust the speed, and now that the lighting is LED from a fluorescent light, a dedicated fluorescent lamp stand that flashes at a commercial frequency is required. Unfortunately, the power cable of the motor comes out from the front and the cable is troublesome, so I wanted it to be put out to the rear. The sound is high-end quality, and the maniac who came to listen to us seemed very surprised. As a turntable that can be purchased at this price, it has a very high quality. It is not recommended for beginners because it requires appropriate knowledge to install the arm and adjust the rotation speed.
This Jasmine belt drive turntable is currently in a model change (image below) incorporating the opinions of Nagai of our shop and Bacoon. Fast action!! However, I do not think that strobe. 。
to theLinear Tracking Arm
When installing JS-TAAB, normalThere was only a space that could be installed somehow by combining two bases on the base of the tone arm, and Nagai seems to have had quite a hard time.
After the installation is completed, the following Nagai-san's hardships are described as it is. 。『The level of the base is adjusted as precisely as possible with a level instrument. The position of the arm is fixed so that the needle tip of the cartridge is at the center of the shaft of the turntable, and the needle pressure of 2g is applied with the needle pressure gauge. Two weights were attached, so it was balanced in the center so that it was easy to balance, but it did not move well. I thought that the air pressure was not enough, but it jumped. Looking at the theory, I realized that only one balance weight was used. If one weight is set to one, it is possible to achieve a zero balance in the DL-103. So it worked out. " It seems that I was struggling with such a feeling, but from the conclusion, the mounting position is limited in linear tracking arm, the adjustment range is limited, it seems to be a phenomenon that occurred because the setting is not clogged. The cartridge can be mounted in a wide range from 6 to 18 g, and if it is DL-103, one weight should be enough.
In fact, the installation photos from the manufacturer are set on the protruding pedestal, and Jasmine has already requested that the protruding pedestal be enclosed with a special adjustment. And I've already received a CAD image of the new pedestal rendering! Work is fast!
Here are some thoughts on the essential linear tracking arm:
"The pump sound is almost silent even when placed nearby. The sound that is played isA completely unshakable sound that I've never heard before. It's not a convenient arm at all,Recommended for those looking for the best sound.』
Bakoon ProductsI never thought I would receive such words from the representative of the company! !
I think the amount is much cheaper than the linear tracking arms that are available all over the world. If you are interested in this arm that Nagai praises, we look forward to seeing you! !
I asked Mr. Nagai to give us another product review, and he was pleased to receive it in a long post. After all, it seems to be a "life" adjustment, either one or two. The secret of analog audio is that paradise awaits you beyond the strict setting. .
- JS-TABB is a linear tracking arm made with air bearings, a product of Jasmine. The arm body and air pump are included in the set, and the pump sends high-pressure air to the air bearing, and the air bearing with the arm floats into the air to eliminate friction, achieving linear tracking. This tone arm allows you to get a clearer sound with a higher resolution, but the adjustment is even more severe. If the adjustment is not made accurately, even the arms will not be able to operate. First, attach the cartridge to the arm to determine the position of the arm. Adjust the cartridge stylus so that it is in the center of the turntable spindle. It can also be adjusted using the included jig. Connect the arm and pump using the included pipe. Switch on the pump and move the pump away until you can't hear the pump noise. The pump is quiet, but if you listen carefully in a quiet state, you will hear a slight sound, so you will no longer hear it after a few meters apart. With the arm in the base position, check the horizontal shaft of the air bearing. The horizontality of this shaft is the most important factor in normal operation of this arm, so precise adjustment is made using a sensitive level. It's fine as long as the base of the turntable is level, but if the horizontal is even slightly off, it may not move, so adjust the shaft horizontally to the precision. Even if you move the arm by hand it won't work properly. The gap between the air bearing and the shaft is only 5 microns, so if you move it with your hands or apply excessive force, it will contact you. Therefore, when moving the arms by hand, be careful to avoid excessive force. Next, apply needle pressure to the cartridge you installed. A pressure gauge is required to apply pressure. As for the lateral balance, there is no needle pressure scale written on the weight. Next, lower the cartridge onto a stationary record and adjust the height of the arm using a commercially available jig so that the cartridge is level. At this time, adjust the air pipe and signal cable connected to the arm and the main unit in a mountain manner as shown in the photo in the instruction manual. It is the cables and pipes that interfere with the movement of the air bearings. Therefore, the distance from the arm's turntable center and the shape of the cable bend greatly affects the operation. These fine adjustments are made by applying the record to allow smooth playback on one side. Therefore, it takes patience to make it work without any problems. However, the quality of the sound you get from this arm is incredible. This will make you forget about the time-consuming adjustments.
About JS-TB297 12-inch Dynamic Balanced Tone Arm
This is a high-end S-shaped long arm from Jasmine's tone arm series. Even though it is high-end, it is priced at mid-class levels compared to domestic and Western products. If it weren't affected by the weak yen, it would be even more affordable.
This JS-TB297 is now becoming closer to Bakuon's reference, so I asked Mr. Nagai to share my thoughts.
--This arm has a unique shape with the center offset from the axis to the right. Needle pressing is a dynamic balance method that has a different pressing mechanism such as a spring rather than a weight. As stated in the catalog, it seems to have absorbed and inherited the essence of the best tone arm design ever. Therefore, there are many similarities to the famous tone arm. However, it is said that this has been achieved through Jasmine's technology to a higher level using the latest precision machining technology and new materials. When listening to it in combination with the company's turntable, the first thing I feel is the high-end sound. The clear and informative sound was praised by those who listened to it as being heard of digital high-resolution. Setting and adjustment is required to demonstrate this ability, and jigs that check the vertical and horizontal of the cartridge, as well as test records that adjust anti-skating will be essential.
To do so, the horizontal level of the turntable must be taken strictly. Use the height adjustment mechanism of the turntable to correctly adjust X and Y in the level instrument. The adjustment of the overhang to determine the position of the arm comes with a dedicated plastic jig, so adjust it using it. Fix the arm base with two screws on the installation base of the turntable. However, although this screw has a rollet, it is not possible to use the driver or wrench, so it is necessary to pinch it with your finger and fix it. The surface is pear processed, and it is slippery, so let's fix it firmly. Since it is an ordinary tone arm that turns in the anti-clock direction and pressurizes, I was confused at first JS-TB297 turning in the clock direction and pressurizing. The available cartridge weighs between 5 and 17 g, but if you attach a light cartridge like the M2 of the company, the balance weight will get close to the center. This makes it difficult to turn the needle pressure pressurized knob and requires adding weight to the cartridge. Next, align the cartridge horizontally and vertically. The correct needle pressure cartridge is lowered to a stationary record, and the horizontal level of the carlidge is adjusted by adjusting the height of the arm using the jig. Vertical adjusts the vertical tilt of the shell by loosening the screw stopping the shell connector of the arm, but I think that it is easy to adjust by using a cartridge with a line that represents vertical such as DL-103 on the cartridge. Since the lateral balance is a static balance, I think that it is good to match the scale, but the inside force canceller is non-linear, so I use the third track on the B side of the Audio Association test record or a dedicated acrylic test record. The needle pressure is applied to lower the needle between 9 cm and 12.5 cm from the center of the track and adjust so that the cartridge does not flow left and right. Strictly speaking, this method is not inside force cancellation, it becomes anti-skating, but less distortion is adjusted. The axis of the inside force canceller's weight contains a scale, but this does not fit at all. Since the cartridge changes greatly, adjustment using the above test record is necessary. When you listen to these adjustments, it is very clear and high-endYou can listen to the wind.
