AAVIK U300 INT. AMP/PHONO/DAC ...THE BEST..RARE..MSRP $30000 INT. AMPLIFIER

Selling for a customer, one owner, less than one year, with original flight case and all accessories. From Denmark, an extreme-end audio equipment both technical and artful. Sitting in the rack since bought new, therefore, though some dust in the second picture, actually like new. The 3rd and 4th pictures are from factory's stock photos.
Only the MSRP  $30000  explains its being rare since it's an INTEGRATED AMPLIFIER, but,not just a common int. amp..... It's with the best phono, the best high-reolution DAC(including USB),  the best line/volume control...at least, it will be very hard to find the better. The background of its design/manufacture/launch is.... a joint project between the designer behind the multiple award-winning loudspeakers of Raidho Acoustics and the high performance cables of Ansuz Acoustics, Michael Borresen, and some of the best analog and digital designers that the world has to offer.

I extracted some things for your quick reference:

Phono/RIAA :
The Aavik U-300 RIAA section is based on a discreet, floating, balanced, ultra-low noise, bipolar input circuit. By nature, the topology of a moving coil cartridge is a floating, balanced signal generator. We have kept this floating, balanced circuit topology throughout the phono stage. The floating input circuitry allows us to use ultra-low noise, bipolar transistors. By paralleling several transistor pairs, we have created a dead-quiet input section. The Aavik U-300 phono stage has a 62 dB gain, and the cartridge loading is adjustable from 50 ohm to 5 kOhm.
The phono section of the Aavik U-300 will let you explore the amazing details and musical depths of your vinyl collection!

• Floating RCA (1 set)
• Load-impedance adjustable from 50 ohm to 5 kOhm;
• Frequency response: +/-0.15dB (20-20 kHz)
• Noise < -100dB re @ 2V out
• Distortion < 0.01% (20-20 kHz)
• RIAA correction curve
• Gain: 62 dB

DAC:
 The Aavik U-300 DAC section is designed around 5 digital inputs, which all excel in performance. The DAC performs without any digital signature, which makes any music sound "analog". The digital circuits are created with the best high frequency skills tools available and great care was embedded in the PCB design. We made a lot of effort to ensure we have a 100% equal treatment of the differential signals, with time-aligned, ultra-short, 4-layer PCB traces. The DAC's circuits are fitted with ultra-low jitter onboard clocks in order to minimize timing errors in the digital-to-analog conversion. In the Aavik U-300 all DAC circuits are isolated with 13 onboard, separate low-noise, high-PSSR voltage regulators each feeding only one stage of the signal handling. The USB input is galvanic isolated to avoid noise pollution from the host. The digital signals from the 5 digital inputs are routed to an ASRC, where they are resampled and re-clocked to 200 kHz/24 bit PCM, feeding current output DAC chips. The current-to-voltage conversion is performed with a differential floating topology with virtual GND. This isolates the signal path from the potential GND noise and signal induced GND modulation.

• 2 x RCA SPDIF (32 – 192 k-samples, 24 bit)
• 2 x TOSLINK optical (32 – 96 k-samples, 24 bit)
• 1 x USB fully isolated, UAC 2, asynchronous (PCM 32 – 192 k-samples, 24 bit)

Line Stage / Volume Control :
 The Aavik U-300 line stage uses a unique, inverted, virtual GND amplifier topology, which preserves the finest musical details on a dark, quiet, black background. The line stage gain can be adjusted between 0-6-12 dB – on the amplifier’s digital inputs the line stage gain can be adjusted 0-6 dB. These adjustments give you the opportunity to adjust individual levels of all inputs on the Aavik U-300 amplifier. The volume control is realized with microprocessor-controlled resistor-ladder (R2R) circuit inside a virtual GND amplification stage. The volume control regulates from -80 dB to 0 dB in approx. 1 dB steps.

• Line 1, Line 2, Line 3
• Gain adjustable in 3 steps (0, 6, 12 dB)
• Input impedance: 10 kOhm
