In October, we began selling Jasmine Audio, a Chinese audio brand.
Jasmine Audio is a highly-known, internationally award-winning pure audio brand founded in China in 2001 by avid audio enthusiasts. The carefully detailed components are carefully assembled by experienced and qualified engineers by hand. Regarding the official brand introduction (abbreviated), the products we ordered are actually very well-made, soBakoon ProductsWith the great cooperation of Representative Nagai, we would like to introduce it to you.
From Jasmine Audio, we are developing everything from cartridges to turntables and phono equalizers to watch records, but the turntables are also only belt drives. The photo is a T-D200MK2. Compatible with double arms. The construction is also very well done. (Of course)

About Belt Drive Turntable TT-D200MK2
We are receiving a report on the setup of the Belt Drive turntable TT-D200MK2.
The 8kg platter is floated with a powerful magnet to make it work very smooth.
but,
The platter is swaying (sweats), but the fact that the magnet is strong and it doesn't sink completely is caused by a stabilizer of about 1kg, which is temporarily resolved. .
After that, following Jasmine's instructions, I cleaned the holes in the bearing with oil and injected the oil to resolve the problem. However, be careful if you add too much oil, it will overflow and ooze for a while. .
This turntable was the last item in stock at the manufacturer, and for some reason it was not packaged in a special case, so I think it was a bit of an impact because it was able to fill it up and sent it in the ready-made form. When I actually contacted the manufacturer, it seems that the symptoms were unprecedented, so I think this problem will not occur if the product is packaged in a dedicated package in the future.
The actual product is very beautifully finished. The turntable supports double arms, but the second one requires an optional protruding base, and it would be much easier to set up if there was a separate base for the tone arm. (Nagai's struggles will be later)
Now, the actions after the problem is resolvedBakoon ProductsApparently, Nagai's performance was above what was expected (lol) and he received a very high praise, saying that this price would not be available in Japan for this much performance! !
We have made an agreement that the Jasmine Audio staff will also directly correct any cautions and corrections that Mr. Nagai pointed out. Jasmine responds to problems very quickly, so you can feel a sense of awareness.
Nagai has given us another review of his TT-D200MK2 over the past two months.
I think its performance as a turntable is excellent. The platter is a magnet installed around the axis and floats about 8mm. I think it's the same principle as the Magnefloat that Teac used to commercialize, but I think it contributes greatly to smooth rotation and prevent vibration. However, the individual I used had a problem with resonance occurring between the magnet float and the belt drive, and up and down vibrations occurred during regeneration, but when oil was injected into the bearing, it no longer vibrates. The platter is floating with a magnet, so if you place a heavy stabilizer on it, the platter will sink and the height of the arm will change. Additionally, the record is supported at six points on the platter, and this support floats slightly from the platter, so if you place the stabilizer on it, the record will warp. It is best to avoid using stabilizers for this product or use lighter ones. The arms can be attached to two arms: a traditional arm and the company's linear tracking arm. A dedicated base is included for mounting conventional tone arms, and can be installed as is with a pipe base arm of the same diameter as the company's arms. If not, you will need to build your own mounting base. The base of the turntable appears to be a laminate of aluminum material. It's heavy enough and looks cool. The base is supported by three rubber feet with bolts and screw them onto the bottom to adjust the height. The rubber feet are as hard as regular rubber, so they do not absorb vibrations here. When you walk on the floor, needles will fly and noise will appear. However, it does not seem to cause howling because the platter is floating with the magnet. The motor is 33 1/3 and 45 rpm, but the variable range is wide and it was able to increase the rpm to 78 rpm even at 33 rpm. A stroboscope is required to adjust the speed, and now that the lighting has changed from fluorescent light to LED, a dedicated fluorescent light stand that flashes at commercial frequencies is required. Unfortunately, the motor's power cable comes out from the front, making it difficult to handle the cable, so I wish it was brought out on the back. The sound was high-end quality, and even the enthusiasts who came to our company to listen to it seemed very surprised. It has a very high quality turntable that can be purchased at this price. It requires a reasonable amount of knowledge to use the arms, adjust the rotation speed, and is not recommended for beginners.
This Jasmine belt drive turntable is currently undergoing a model change (image image below) taking into account the opinions of our store and Mr. Nagai from Bakuon. Actions quickly! ! However, I don't think there's a flash. .
For TT-D200MK2Linear Tracking Arm
When installing JS-TAAB, the normalNagai seemed to have had a lot of trouble with the space to connect two bases by combining the tone arm base.
After the installation is finally complete, we will explain the difficulties involved in Nagai's setting as is. . "The horizontal base is adjusted to the level as precisely as possible with a level. The arm is fixed so that the tip of the cartridge is in the center of the shaft of the turntable, and apply a 2g pressure gauge to apply a needle pressure of 2g. There were two weights, so I balanced it in the center to make it easier to balance, but it didn't work well. I thought I wasn't getting enough air pressure and raised it to the maximum, but it still flew by. Looking at the instruction manual, I realized that I only used one balance weight. If you put one weight, the DL-103 will achieve just the zero balance. So when I played it, it worked. It seems that there was a lot of trouble, like this, but to put it simply, this phenomenon occurred because the adjustment range is limited with the linear tracking arm, and the setting was not fully completed. The cartridge can also be installed over a wide range of 6-18g, so with the DL-103, one weight should be enough for you.
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 this, you need to keep the turntable level strictly. Use the turntable height adjustment mechanism to correctly adjust the X and Y using the level. A special plastic jig comes with an overhang that determines the position of the arm, so you can use it to adjust it. Secure the arm base to the turntable mounting base with two screws. However, although this screw has a knurled screw, it is not suitable for use with a screwdriver or wrench, so you will need to pinch it with your fingers and turn it to secure it. The surface is coated with a pear finish, so it is slippery and securely secured. Since it is a normal tone arm that is turned counterclockwise to pressurize, I was initially confused by the JS-TB297 that is turned clockwise to pressurize. The usable cartridge weighs 5-17g, but when you install a light cartridge like the company's M2, the balance weight will just close to the center. This makes it difficult to turn the needle pressure knob and will require weights to be added to the cartridge. Next, align the cartridge horizontally and vertically. Remove the cartridge with the appropriate pressure applied to a stationary record, and use a commercially available jig to adjust the arm height and adjust the horizontal position of the cartridge using a jig. For vertical use, loosen the screw that holds the shell connector on the arm to adjust the vertical tilt of the shell, but I think it will be easier to match if you use a cartridge with a line indicating verticality such as the DL-103. The lateral balance is a static balance, so it's best to match the scale, but since the inside force scan seller is non-linear, you can use the third track on the B side of the Audio Association test record, or a dedicated acrylic test record. Apply the needle pressure to remove the needle between 9cm and 12.5cm from the center of the track and adjust the cartridge to prevent it from flowing left and right. Strictly speaking, this method is anti-skating rather than inside force cancellation, but adjusting it will reduce distortion. There is a scale on the weight axis of the Inside Force Scan Seller, but this is not a factor at all. As it varies greatly depending on the cartridge, adjustments using the above test records are necessary. By making these adjustments and listening, you can hear very clear, high-end sounds with high resolution.
