First look
Though not from the same manufacturer (not even from the same country), the Blue Note and the BG Radia units were both black in hue that gelled together very beautifully in terms of aesthetics. While the Z-92 is clad in a rusty old school black-ash finish, the Blue Note products are dressed in a mildly lustrous piano black finish on the front panels. With not many embellishments, except for the tiny silver switches, both these products display a minimalist design approach.
Technological aspects
Blue Note Mini Koala CD Player
Bearing the critical responsibility as the source in this system is the Mini Koala CD player, an entry level product from the renowned italian company, Biuenoten, now goldenote. it incorporates a drawer type transport designed to achieve a sturdy disc rotation mechanism. Assisting this system is the Mini Koala's special Electro-Power power supply system that is a self-adjusting power supply, which enables the player to reduce speed fluctuations (of the transport) lower than 0.0001% in any electrical system within 100 to 260 volts. For clocking purposes, it uses a proprietary Zero Clock mechanism, which makes sure that all the internal parts, mainly the transport and the DAC, are working in sync with each other so that there is practically no jitter. As for the DAC. it uses an original filter that allows the Mini Koala to reproduce a very wide bandwidth with very low signal compression.
Blue Note (Goldenote) S-l Signature Integrated Amplifier
Next in line is the S-l integrated amplifier, also an entry level product that incorporates a special proprietary amplification design called Mirror-Amp design. It works very similarly to the balanced circuit designs, where you have a mirror signal generated to eliminate any noise by using the common mode rejection method. For power supply in the S-l, they have used two different custom made transformers. The transformers are dedicated to the audio signal, while an internal galvanlcally insulated power section controls all the functions that could adversely affect the sound of the amplifier, such as the motorlzed volume control, checking relays, power 'On' LED light besides the micro-chip used for some electro-mechanical functions.
BG Radia Z-92 Floor Standing Speakers
The highlight of the Z-92 (Just like all other BG Radia speakers) is the coaxially-mounted mid and high frequency planar ribbon drivers. Planar drivers have inherited the benefits of a faster response time than any other loudspeaker driver technology available till date. But the trick is that they have used these planar drivers even for the mids section, which makes it even more alive for the listener. The planar speakers enables the speaker to have an unprecedented transient response and dispersion for the mids, which form the core of any genre of music. The rapid transient response and a wide dispersion throw results in a sound that is detailed and crystal clear. And to complement this clarity in the mids and the highs, they have the twin 6.5" black aluminum cone woofers featuring double-gap motors and neodymium magnets. The two drivers promise excellent dynamics with a tight, clean bass response.
For the speaker connectors, they have used high quality gold plated brass insulated with Teflon washers and bolts that carry the pristine signal to the next component in line, the BG Radia Z-92 speakers.
