Audio Research VSi 75 integrated amplifier


Power Output: 75 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1.5% at 75 watts, .05% at 1 watt.
Approximate actual power available at “clipping” 80 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
Power Bandwidth: (-3dB points) 12Hz to 70kHz.
Frequency Response: (-3dB points at 1 watt) 1.0Hz to 70 kHz.
Input Sensitivity: 0.55V RMS Single-ended for rated output. (32.5dB gain into 8 ohms.)
Input Impedance: 52.5K ohms Single-ended.
Inputs (5): 1, 2, 3, 4, 5 (Single Ended RCA connectors).
Maximum Input: 10V RMS (any input).
Output Polarity: Non-Inverting (any input).
Push Buttons: Volume up, Volume down (103 steps), Power, Input, Mute, Bias. All functions on IR remote control.
Output Taps: 8 ohms, 4 ohms.
Output Regulation: Approximately 2dB 8 ohm load to open circuit (Damping factor approximately 4).
Overall Negative Feedback: 4dB.
Slew Rate: 10 volts/microsecond.
Rise Time: 4 microseconds.
Hum & Noise: Less than 1.0 mV RMS -88dB below rated output (IHF weighted, Vol down).
Power Supplies: Electronically regulated Low and High voltage supplies for input stages. Automatic 40 sec. warm-up/brown- out mute.
Power Supply Energy Storage: Approximately 350 joules.
Power Requirements: 100-125VAC 60Hz (200-250VAC 50Hz) 400 watts at rated output, 600 watts maximum, 210 watts at
“idle’: 1.0 watt power off.
Tubes Required: 2-Matched pair KT120-Power Output; 2 -6H30 driver.
Dimensions: Width 14.5” (36.8 cm) Height 9.25” (23.5 cm)
Depth 16.25” (41.3 cm) Rear connectors extend .88” beyond chassis.
Weight: 36.4 lbs. (16.5 kg) Net; 49.3 lbs. (22.4 kg) Shipping.

Totaldac D1-digital reclocker


The D1-digital is a new concept of reclocker. It aims at improving the sound of a digital system.
It is connected between a drive (CD player, computer with USB, music server) and any 24bit DAC.

The D1-dual uses the same technologies as the D1-dual DAC but the analog outputs have been replaced by digital outputs.
So it has multiple digital inputs, an 69bit volume control which can be used or not and even more interesting a FIFO memory and an internal clock which attenuates the jitter of any digital source.

So the D1-digital reclocker is compatible with all available drives and all available DACs.
It can be also used as a USB to AES-EBU or spdif converter with high sound quality.
Even associated with the D1-dual it can de-jitter any digital source to get an unexpected better sound when the source is a computer, a music server or a CD drive.

-192KHz asynchronous Xmos USB, optical, RCA and AES-EBU digital inputs, selectable from a remote control.
-44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz and 192KHz, 16 to 24 bit formats supported on all inputs except 96KHz max for optical input.
-USB input compatible with Jplay in 24 bit "extreme hibernate" mode.
-AES-EBU and spdif (RCA or BNC) digital outputs.
-69bit digital volume control, adjusted by a remote control and an OLED display. The remote control receiver can be disable by a switch to dedicate the remote control to the D1-dual when the D1-digital stettings are finished and saved.
-phase polarity selected by remote control.
-display switch off by remote control or automatic.
-all unused inputs are completely disconnected (including the ground) to keep the optimum noise floor even when several sources are connected.
-external power supply to minimize the noise.
-aluminium and PMMA enclosure.
-power consumption 18W.
-DAC dimensions: height 110mm, width 360mm, depth 290mm.
-power supply dimensions: height 65mm, width 122mm, depth 180mm.

Available options:

-silver massive aluminium front panel and silver lid.
-Adjustable 12dB/oct high pass filter for D1-dual, to attenuate sub bass to solve a room acoustics problem or to protect the loudspeakers or to remove sub bass when listening with a headphone or to remove the recording offset or to preserve neighbours or children at night.
-115V power option.
-BNC coaxial digital input and output instead of RCA.
-D2-digital, 69 bit 2 way active crossover including the main volume control and also for the relative level between bass and treble. The crossover slope can be 6dB/oct, 12dB/oct or 18dB/oct. All parameters, crossover frequency, filter slope, relative volume, main volume, relative digital delay... can be controlled from the remote while listening to music.

FM Acoustics 268+1811

Both units is FS at a dealer in China.
Both are brand new and can only be bought together as a set.
No discount so total price is $280,000.

Not every day this set is FS as there is 6 months waiting time.

A 115 pair on top of 1811.

T+A PA 3000 HV Integrated Amplifier
