Unique, Innovative, Rarely Japanese Audio for Audiophile!!
Famous, Historical, Vintage Japanese Audio Device!!Bakoon Products PRE-5430 PreamplifierBring out the power amplifier’s performance by 120%!PRE-5430 is a preamp developed as an anniversary model together with the main amp AMP-7511A.It has three voltage inputs and two SATRI-LINK current inputs, and the gain of the amplifier can be continuously varied up to 20dB. The output circuit has been changed to a circuit that matches the preamplifier, using the circuit of the main amplifier AMP-5521, which is popular for its deep sound. The PRE-5430 replaces the CPU-controlled discrete volume of the advanced model PRE-5410 MK3 with a standard volume and high-precision attenuator, and suppresses the price by omitting luxurious functions while increasing the accuracy of the main PCB circuit. The front panel has a very simple appearance without the LCD display. The gain controller controls the preamp gain from 0 to 20dB. Unlike normal volume control, S / N does not deteriorate even when the volume is lowered, so you can enjoy music at low volume with confidence even at midnight. Also, PRE-5430 is designed for speed. The sense of speed refers to the time from when a signal is input to when sound is output from the speakers. From the experience of making professional PA equipment, Bakoon recognizes the importance of a sense of speed and incorporate it into the design. If there is a sense of speed, howling does not occur from the speaker. The preamplifier functions as an interface for audio signals. In other words, it makes a kind of correction so that the power amplifier amplifies the input music signal correctly. Generally, the source equipment of a vacuum tube has a high output impedance, usually about 1 kohms. TR source equipment is about tens of ohms. Bakoon’s preamplifier corrects the signal of the source, reduces the output impedance to less than 10 ohms (for RCA output), and sends it to the power amplifier. The lower the output impedance of the preamplifier, the better the power amplifier will perform. Furthermore, it is possible to increase the driving power of the speaker. And SATRI link. By using this link, the preamplifier and the power amplifier behave like a single component. It is hardly affected by external noise. However, if you use a good quality RCA cable, you can approach a similar level without using the SATRI link. This unit can fully demonstrate the ability of other models of main amplifiers without being particular about SATRI link.

REVIEW The speaker used for audition is Casta Acoustics’ Model C .. A cool sound unique to the horn, but the high density of the midrange is more than expected. Complete, dynamic, and finely expressive. I thought this was a different speaker? For example, 1st movement of the Violin Concerto by Tchaikovsky played by Heifetz. As one of the living recordings of living stereos, their strengths stand out well. A little bit of hiss and the flexible, natural taste of analog recording is a gem. Heifetz’s presence with powerful charisma shines like a jewel. What kind of harmony is it?Listening to Neil’s Rope Gren’s ‘Keith Don’t Go’, the complex guitar play as if you were playing two people entertains your ears, and the lively realistic feel is reproduced properly. Delivered. Energy, tone, and finesse are all in harmony.Then I listened to Pink Floyd’s “Money”. The positioning of the various effect notes is accurate once. Touching the cash register, people’s conversations are heard everywhere. In time, the band’s play began to unfold in three dimensions. In particular, the tenor saxophone’s booming performances offer the charm that only horn type speakers can produce. Wow, look at this? Naturally, I thought Bakoon’s 100W output amplifier was a match, but surprisingly, the 15W SCA-7500K is hanging. surely? But it is true. However, there is one trick here. The PRE-5430 preamp. Preamp? Did you walk this and the 15W output suddenly changed to 30W? No, the output is the same. However, there is a difference in speaker driving power. What do you mean? Bakoon’s preamplifier corrects the signal of the source and lowers the output impedance, making the power amplifier perform at its best.If you already have a Bakoon main amplifier, do not replace it and add this unit to enhance the completeness of the system.*Monthly Audio
