Bakoon Products PRE-7610MK4 Preamplifier

The PRE-7610 MK4 successfully defeats the argument that a preamplifier is not required for a power amplifier with volume, giving the power amplifier more drive power and a huge amount of information. It is also possible to control power amplifiers from other manufacturers. This unit is equipped with a total of 5 input systems, including 3 voltage inputs and 2 current input SATRI-LINK systems. The output can also be combined with the company's SATRI-LINK input power amplifier to create a full current transmission system.

By installing a new circuit, it has demonstrated performance that far surpasses that of MK3. Despite its compact size of 78 mm (H) x 235 mm (W) x 295 mm (D), it has content and performance that is not inferior to the high-end class. The addition of the newly developed HIBIKI-IC to the SATRI-IC circuit has increased the thickness, amount of information, and reality of the sound. The originally vast range is even wider, and it extends from low to high frequencies without stress, giving you a very natural sound. The sound image is clear, each instrument can be heard comfortably, and the background is deep and calm and quiet, so it's like listening to it in a live hall!　The bias adjustment time at power-on has also been dramatically increased to less than 30 seconds.

With the addition of the PRE-7610 MK4 preamp, you can feel the increase in the amount of information. The more dull the music looks from the monitor's ATC speakers, the higher the resolution. The sound of chords and bows scraping, the sound of the crowd talking, the sound of stepping on the floor, the sound of the breathing of the performers and singers is vividly transmitted, as if looking through transparent glass. It's as if the world reappeared on the day I put on my glasses for the first time without noticing that my eyes had deteriorated.
First, listen to the Royal Philharmonic Orchestra conducted by Rene Lebovitz in "A Night on Bald Mountain" and "Pictures at an Exhibition." The change when PRE-7610 is added to SCA-7511 can be felt very clearly and directly. The first thing you will notice is an increase in volume. If you are a user who has been dissatisfied with the output of the SCA-7511, you can see that the introduction of a preamplifier has a considerable effect in securing volume. You will feel as if you have changed from a 4-cylinder car to an 8-cylinder car. Next, you can directly experience the expansion of the space. The width and depth of the stage are expanded at the same time. What is particularly impressive is the expression of the depth of the stage, which enhances the expressiveness of the "hierarchy" of each instrument group in the orchestra, making it possible to enjoy the performance more realistically. The string parts are thicker and smoother in terms of texture, and the brass parts are full of brilliance. And the faithful reproduction of the bass sound could not help but admire.
Next, listen to the Bill Evans Trio album. The point of appreciation is how to vividly reproduce the whole tones peculiar to live performances. The track I played was "Porgy". First of all, you can feel that the air on the stage and in the auditorium becomes transparent at once. The sound of the audience talking and the clashing of wine glasses in the audience is very realistic. If you listen closely, you can discern the content of the audience's conversation. June 25, 1961, New York, the Village Vanguard air approached here. Bill Evans' transparent yet warm touch, his indulgent rhythms in Scott Rafa, and above all, Paul Mortian's gorgeous, understated technique fill the transparent space. Even considering that it is a 24-bit/192kHz sound source, the fact that it was recorded half a century ago is an incredibly faithful reproduction. The combination of SCA-7511 MK3 alone seems to be an elegant reproduction that could not be expected. Even though it was an album that I loved, there were some aspects that I was not satisfied with the usual playback, but with the introduction of the PRE-7610 MK4, I was able to eliminate most of those complaints. In particular, the refreshing sound of cymbals bursting like bubbles of carbonated water was truly exquisite.
