Audio Grade Solder HMX Review
Different from conventional solders that are supposed to be audio grade, the soldering makes you feel a sense of refinedness in the recorded sound and the replayed sound. It does not mean the reaction to the sound source is dull, but I had the impression that the reproduction of the sound source details was being done at an extremely advanced dimension.

Audio Grade Solder HMX Review
First, it was an eye-opener that soldering changed the sound this much. Music consists of many elements overlapping, and how much quality you can form in the “mille-feuille” makes an unbelievable difference in intensity as the final output of spirit. Therefore, if you start to care about the soldering of all the parts, (as a guitarist would have many effectors), I can imagine a fantastic future ahead of it, and the kind of people who have a strong sense of inquiry would be addicted to soldering for sure. I’m looking forward to the future of it.

Audio Grade Solder HMX Review
KOJIMA SOLDER FACTORY CO., LTD. Audio Grade Solder HMX Series Review
Up to now, I thought the type of mic changed the drum sound, and I never thought that the soldering used on the cable could change the sound of the drum. First, you can control how thick the sound is. Next, you can control how vibrant the sound is. Drum sets use a lot of mics, so I think the effect of soldering is great. Be sure to try it!!

Audio Grade Solder HMX Review
A special point of the HMX series is the speed at which the sound start-up.
Band balance changes depending on the composition, but all models have a minimal accent in sound and accurately express attack part details that are central to the performance. Even subtle overtone starting can be replayed without any loss, so you can feel a hot sense of overtone and sound pushing out that you could only get with vintage solders, and still at the same time, there is no strange exaggeration. I feel that it has a quality, unlike any other product in the past.

“Toshiaki Yanagi” Review of sound tone by product
Sn-Ag-Cu
It has one of the most amounts of information in all the bands, and the impression is that words like “modern” and “hi-fi” suit the best. It not only sticks in a simple flashy manner, but it captures without giving up until the sound retreats. It is unlike any other existing soldering with silver. When recording, it captures subtle changes in the touch of your hand, so you could say that professionals would tend to like this product. It would do a good job when recording string instrument sounds like guitars and violins.
Sn-Cu-Ni+Ge
I felt it has the most ideal semi-cylindrical frequency characteristic. While maintaining the amount of high-frequency information to make it not feel plain, it seems to contribute significantly to mid-frequency resolution and stereoscopy. It has the potential to be able to hear the cutting ends of sounds when you listen carefully. You will not go wrong with choosing this solder as the first choice when recording vocals.
Sn-Pb
I have listened to the sound of mainly lead solders for a long time, but I barely felt the slowness unique to the lead produced sounds. You can feel absolute comfort in the richness of the mid-frequency, and as the new lead solder approach, I felt it was a perfect finish. From the perspective of a recording engineer, I consider it will be used a lot for summing bass tracks.

Sn-Ag-Cu
This one seemed to have the vibrant part at the top coming out to the front, and in total, the range seemed to have widened, and it was the most hi-fi. When you listen to it on its own, it was magnificent with flashiness and profoundness, but mixed in an ensemble, it starts fast in the upper band, so sometimes it may sound light, but as the range is wide, it may have the most range of width. I think many guitarists like this because it is the most vibrant. (lol)
Sn-Cu-Ni+Ge
It has a different sense than lead in the sense that profoundness is added. I think it is suitable for instruments like acoustic guitars where the low tone is vital. Sometimes, the low tone could just be a sound distortion, but I could solidly hear the presence of the low tone as a pitch. In terms of acoustic guitars, it feels terrific playing it.
Sn-Pb
Compared to standard tin-lead solders, the sound output from the speaker seems to form a precise sound image. What this means is that it has a broad and stable sense in the mid-frequency, so it would match musical instruments that value these bands. The best way to express it is that it sounds committed.
“Takahiro Toda” Review of sound tone by product
Sn-Ag-Cu
It has a broad sense of range unique to silver, and fast starting unique to this series. These two effects create synergy to actualize overwhelming overtones and pushing out. Compared to others, it almost feels that the volume went up. It’s so powerful that you may need to select the source, but it is guaranteed that you would want to hear all the sound sources you have all over again. For musical instruments, it matches bass guitars so well you won’t be able to let go. Everything changes, including distorted guitars. The amount of information is the best, so try this solder first, and if you need to, you can take away things so that you can find the perfect point right away.
Sn-Cu-Ni+Ge
It has a warm thickness in the low-frequency, suitably extended high-frequency, and softness, and depth of the mid-frequency, which makes the perfect balance. It is a balance that matches well to the human auditory sensation. Although it has a resolution that allows you to hear to the detail, as a special expression, it is smooth and soft. The high-frequency range does not extend too much, yet it has an open resonance. It is the best sound quality for listening. The trend is the same in recording as well, as it is not pushy, and you can get a sound image that is soft and penetrates. It would do a fantastic job with live instruments, especially collecting the sound of vocals.
Sn-Pb
Maybe it’s because my ears are used to listening to traditional compositions, but this one has the best band balance that makes me feel comfortable after hearing it. It has a low center of balance like lead (Pb) but has a resonance with grit in the mid-frequency, yet it doesn’t have the dull sound, which is the weakness of lead. Although the extension in the high-frequency is inferior to silver, the start of high-frequency within the band is extremely fast, so you don’t feel much of a disadvantage. When listening, the source with a sense of lo-fi creates a soothing heaviness when replayed. For musical instruments, it would match instruments like single-coil electric guitars and parts where you want to bring the sound image to a low position.
