Eagleeyes Posted July 24, 2021 Posted July 24, 2021 Excellent condition Esoteric I-05 Integrated amp with phono stage. Bought very recently for second system as was having my tube amps repaired and now back as issue was very minor so can sell this beauty again on here. Has box remote and manual which for some reason I forgot to take pics of. Very good condition a few minor marks hard to really see, I would rate it a 8.5 or 9 out of 10. Info from Dr google... Esoteric MSW* Pure Class D Mono Block Power Amplifier*MSW= Master Sound Works • Introducing the design know-how of professional studio-use power amplifiers The power amplifier is at the core of our integrated amplifier, the I-05.Esoteric has introduced techniques collected through the trials of designing professional studio-use power amplifiers into the power amplifier sections of I-05. The power amplifier of the I-05 continuously balances outstanding drive power along with natural tones and conveys the essence of a master sound recording regardless of the size and efficiency of the speaker combinations being used. • Esoteric's MSW Pure Class D power amplifier with dual mono architecture The I-05 is equipped with a MSW Pure Class D power amplifier that uses the latest high-speed MOS-FET devices in a 2-parallel configuration to achieve superior speaker drive performance. This circuit uses separate power amplifier blocks mounted in a dual mono architecture. This allows each channel to obtain a high practical-use maximum output of 190W+190W (6Ω). • Linear (analog) power circuit supplying strong driving performance The power circuit is equipped with a high capacity custom EI core transformer that generates tenacious yet silky sound quality. The smoothing condenser achieves a great balance between high capacity and low impedance by means of a parallel connection of four circuits to each channel. Also, strategic placement of the power amplifier on the board shortens the signal path, which means a faster power supply. Furthermore, the high speed Schottky barrier diode is used for its low noise when rectifying. The linear power source, which boasts low noise and abundant power, contributes greatly to the unit's excellent sound quality. * The power source of the amplifier is the heart that determines the performance and tonal quality of the amplifier. The I-05 satisfies both pure and warm tones along with strong driving performance by combining the traditional linear (analog) power source and the latest amplifier stage which easily drives even low-efficient speakers. This might even give the listener a feeling that there are no speakers at all. Full-balance Designed Dual-mono Preamplifier • Full-balance preamplifier circuit thoroughly suppressing noise The preamplifier is carefully designed carrying over the award-winning technologies introduced into the C-03. The application of a fullybalanced configuration reduces noise to the limit. The mounting point is located at the rearmost area of the chassis, which is closest to the input terminal. • Esoteric-QVCS (QVCS = Quad Volume Control System) By turning the volume knob, the variable volume gain of all four circuits – right and left channels, positive and negative powers – are activated by control signals that are transmitted to the preamplifier. In this way, the system keeps left and right audio signals independent from each other and from positive to negative. The benefit being that sounds are heard clearly with good channel separation and accurate phase characteristics. Furthermore, the deletion of a cable from the audio board to the volume device radically shortens the audio signal path and thus stops sound deterioration. The volume device uses the New JRC “MUSES,” tried-and-trusted for its sound quality • Low noise operation capable of reproducing minute dynamics The control board for the entire Esoteric-QVCS is physically separated from the preamplifier board. A measure is being taken here also for downright low noise operation, which is to completely stop the control microcomputer, unless the operation launch is accepted. • Functions utilized by the high grade preamplifier The preamplifier is equipped with a PRE OUT terminal system, accepts biamp configuration and also serves as a fully-balanced dual-mono preamplifier so as to be compatible to future system upgrades. The headphone terminal is available for personal listening using your favorite pair of high-quality headphones.

075Congo Posted July 24, 2021 Posted July 24, 2021 Fantastic amp! I'm the original owner; bought from Cameron at Krispy Audio and traded it in on a Esoteric F-05 Integrated. GLWTS Cheers 1
