Brunoco Diva Digital Amplifier
is the ultimate digital amplifier with integrated DAC/ADC/EQ for today’s digital music reproduction needs. All you need is source of your choice (digital or analog), ENTRON DIVA, and speakers.
The amplifier is as good as the power supply. We adapted analog power supply for musicality instead of SMPS(switching mode power supply) which is commonly used due to cost and size. Separate transformer supplies good quality current to the circuit, and oversized reservoir capacitors guarantee rich, pleasant sound.

Performance
The Prism Sound DA-2, 96kHz, 24-bit D/A converter provides ultimate-quality monitoring of digital audio signals. Its exceptional linearity and rock-steady clock generation and recovery ensure the highest conversion precision available for recording and mastering applications.
The DA-2 combines truly state-of-the-art audio performance with the advanced features needed by the professional to provide the most revealing, most transparent and most flexible digital to analogue conversion unit available.
Ayon Audio is pleased to introduce the superb Skylla II DAC featuring a fully balanced digital and analog design. In its digital section, four Burr-Brown PCM -1704K DACs are arrayed in a true differential dual mono configuration. The differential gain stage is composed of two 6H30 high-current tubes per channel. The Skylla II DAC features a vastly overrated, high capacity power supply for the 6H30 analog output stage with tube “bridge” rectification, choke coupling, three oversized power transformers, two for the analog and one for the digital section.

Minimal discrete wiring for optimum signal propagation
No followers or buffers in the signal path
High quality parts throughout
Fully hand assembled to insure the highest level of craftsmanship
Separate analog output stage for left and right channel
Burr Brown D/A converter

Power Supply
The power supplies have been further refined with new components and enhanced AC line noise filtration. Separate power transformer windings and filters provide total isolation between the input and output stage which makes this a pure power source and it is a critical attribute for a 6H30 output stage. We also use electrolytic capacitors with much larger storage capacity to make up for the loss in filtering when using resistors in lieu of inductors.
3 separate R-Core / Low noise – insulated power transformer for digital & analog
Tube rectification
Dual choke – filtered power supply and coupled with special film caps
Innovative power supply provides a high speed energy delivery on transients
Separate and isolated power supplies over each stage of amplification
Regulated DC filament supplies with soft start for 6H30
AC power line filter to avoid noise and hash from entering into the unit.
10 separate voltage regulators
The Lindemann USB-DAC 24/192 is a digital to analog converter with a resolution of 24 bit and 192 kHz. The USB-DAC 24/192 operates in asynchronous mode (USB Audio Class 2) and allows music files to be played via the USB port of a PC or a Mac.

Overdrive Technology
The performance of the Overdrive DAC is a result of several innovative design breakthroughs
Low jitter Clocks
Low jitter 192 Async USB interface module
Ultra-Simple pure Class-A analog Path
D/A Volume Control
Ultra-Linear Output Stage
Fully Balanced Analog Path
A large number of Black-Gate electrolytic capacitors
Point-to-Point silver wiring for the analog output stages — Signature version
High quality output coupling caps — V-Caps and Sonicap Platinums
Low jitter/Upgrade Clocks
The Overdrive requires 2 clocks in the USB module section because of the asynchronous USB protocol. The other inputs (S/PDIF and I2S) are clocked by the incoming stream. The two clocks provide for the two sample rate ranges on USB: 44.1/88.2/176.4 and 48/96/192. The standard clocks used in the Overdrive are upgraded monolithic clocks with very low jitter. We also off the dual Turboclock, which is an extremely low jitter upgrade clock with 2 Hynes voltage regulators.
