All-purpose power amplifier with a new generation of circuits
A new generation amplifier with MK4 circuit
The SCA-7511MK4 has a completely new base design to increase the thickness, amount of information, and realism of the sound. When the power is turned on, it starts up in 30 seconds, which is much faster. While retaining the MK3's ability to reproduce an overwhelming amount of information, the MK4 is equipped with a newly developed impedance adjustment circuit for input and output. As a result, the amount of information is further increased, and the overwhelming amount of information of high-bit and high-sampling can be reproduced with a realistic sound that is comparable to that of high-end class.
The MK3 had two voltage inputs, but the MK4 uses one voltage input and one current input, and it is possible to obtain even higher sound quality by using SATRI-LINK.
The SCA-7511MK4 is equipped with a BTL mode, and you can easily switch from a stereo amplifier to a monaural amplifier with a switch on the rear panel, and by using two SCA-7511MK4s, you can enjoy a full-fledged monaural sound with much higher output and no distortion.
It has a clear, natural sound and a deep and quiet background, and it has the strength to be enough to play in a normal room. Connect your CD player directly and enjoy the sound of a real CD that you have never heard before. It is a versatile amplifier that also has the performance of a full-fledged headphone amplifier.

*Bakun Products will gradually change its logo and name to SCL (SATRI Circuit Laboratory). Thank you for your understanding.
It was the SCA-7511MK4 that was sent. The number of switches on the front and rear panels has increased compared to the MK3. After finishing the wiring, I listened to it first. As I turned it on and played the CD and waited for the amp's bias to stabilize, I didn't hear the first rattle that was unique to Bakun. If you are a user of Bakun Products, you will understand, but you will be surprised when a beautiful sound suddenly comes out of the speaker at the start. That's how fast the MK4's bias stabilizes!
THANKFULLY, THE MK3 IS EQUIPPED WITH SATRI-LINK, WHICH WAS NOT INSTALLED, SO YOU CAN ENJOY THE COMBINATION WITH OTHER BAKUN PRODUCTS WITH CURRENT OUTPUT.
Amateurs don't know how much of a new circuit called HIBIKI-IC is, but it's completely close to live sound. It's been pretty good so far, but it's the closest to the live sound I've heard. In any case, the sound field is close to the sound you hear in an actual concert hall. It doesn't feel electrical at all. I don't feel like I'm trying my best to be so-called crunchy. It's not a three-dimensional feeling that is created, but the sound that should come out reaches it firmly, or the perspective is perfect. It's very close to the feeling of listening from a certain distance rather than directly behind the conductor.
The sound itself and the sound field are very natural and unpretentious. The vocals are also wonderful, and you will be drawn in more and more.
It's more than singing in front of you, it's more like a feeling. Anyway, the subtle nuances of the voice are conveyed.
I don't get tired no matter how many hours I listen to it, on the contrary, it makes me feel better, I feel real when I listen to it seriously, and I don't mind it at all even if it is played as background music.
The resolution and SN are even better. The spread of sound is not as high as that of the MK3. The sense of reality at low volume is also wonderful. The sound doesn't lose weight at all. It just makes you feel like you're listening to it from a distance. The vocals are very natural, soft and not tingling at all.
What's even more noteworthy about this amp is that it is equipped with a BTL mode, and you can easily switch between stereo and mono with a switch on the back, so if you have two SCA-7511MK4s, you can enjoy a much more powerful sound in monaural specifications. It is an attractive option that has been proven in the high-end models AMP-5511 and AMP-7510A.
