A NEW AMPLIFIER AND THE MATCHING PRE HAVE JUST BEEN RELEASED BY FRENCH HIFI BRAND TOTALDAC

The Totaldac Amp-1-sublime and Totaldac d1-driver-sublime preamplifier have been designed to work together, and as part of a complete Totaldac system.

Sublime is Totaldac’s flagship range of products.

TOTALDAC AMP-1-SUBLIME AMPLIFIER

The Totaldac Amp-1-sublime is the new Totaldac reference amplifier, using solid state components exclusively and available in stereo or monoblock variations.

NEXT GENERATION

The triode stage used in the previous generation of Amp-1 is now upgraded by an innovative transistor gain stage, using very low component count (all discrete) and no global feedback.

VISHAY RESISTORS

A very high voltage (240Vdc) is used to give the maximum dynamic to the signal and its power supply is based on a discrete regulator as well. The circuit uses 0.01% VAR Bulk Metal Foil resistors from Vishay in the critical voltage gain stage. The gain stage is then followed by an equally powerful transistor buffer, using no global feedback as well.

This design combines no global feedback, low noise (0.2mVrms), high gain (33dB), high bandwidth (400KHz) and high current (driving 1ohm) thanks to its 2500VA/25kg live-power transformer.

STEREO OR MONOBLOCKS

The Amp-1-sublime amplifier is available as stereo amplifier with RCA inputs or as fully balanced monobloc with XLR input.

TOTALDAC D1-DRIVER-SUBLIME PREAMPLIFIER

A new d1-driver-sublime preamplifier has also been designed by Totaldac to perfectly match the new amplifier.

The d1-driver-sublime has no volume control because it relies on the DAC volume control but in case the complete system gain is too high (DAC + amp + speakers + room) an analogue -15.5dB attenuation can be activated using a switch at the back panel. This attenuator uses 12 pieces of 0.01% VAR Bulk Metal® Foil resistors from Vishay.

SPECIFICATIONS

-one-box stereo version: RCA inputs, RCA outputs + unbalanced XLR outputs
-two-box monobloc version: RCA inputs + XLR inputs, RCA outputs + balanced XLR outputs
-voltage gain: 0dB gain (x1 factor) or -15.5dB attenuation, selected by a swict on the back panel
-very high bias current class A design for a natural low output impedance and low distorsion
-very high grade components in the signal path, and no capacitor in the signal path.
-extreme low noise due to discrete design (no IC at all) and external power supply, matching the noise of d1-sublime DAC
-input impedance: 12Kohm
-natural low output impedance plus added 33ohm pure resitor for a perfect interconnect impedance matching
-can drive anything above 100ohm without distorsion
-distorsion: 0.0025%
-frequency cut-off at -3dB, RCA output: 2.5MHz
-using 12 pieces of 0.01% VAR Bulk Metal® Foil resistors from Vishay in the attenuator and 4 in the balanced output
-aluminium and PMMA enclosure with massive pure copper antivibration plate
-power consumption 20W
-main box dimensions: height 110mm, width 360mm, depth 290mm
-power supply dimensions: height 65mm, width 122mm, depth 180mm
-weight: 7kg
Available options:
-damping feet.
-one-box stereo version or monoblocs version.
-two pairs of outputs for a subwoofer or a headphone amplifier or for bi-amping.
-silver massive aluminium front panel.
-115V power option.

COMPLETE TOTALDAC SYSTEM

In case the complete system is missing some gain with some tracks recorded very low, the latest Totaldac DACs offer a +12dB digital gain option, giving  two selectable gain options in a Totaldac system to optimize all configurations.
