Phono stage :
To build a great sounding and technically perfect Phono Preamp is one of
the biggest challenges in HiFi-but easy for you-Tango ULTIMATE.
You need - exact equalization of the input signal - which can only be
achieved by using high-precision components in the equalizer of the Phono
amplifier. Therefore, we measure each single part with high-precision
measuring instruments. The values of the components used are hand selected
here on a deviation of less than 1%! For the two stereo channels also always
identical pairs are to ensure perfect equal channels. All this efforts are
done to get an almost entirely linear output voltage from the Tango
ULTIMATE. We use a passive EQ network followed by an active network which
gives the best results.
Additionally - high, adjustable gain - The Signal delivered by the cartridge
is very very low. The needed amplification also amplifies the noise and hum
which is naturally involved in any electronic device. We are using specially
designed devices which have incredible low noise and accuracy so the result
is a very high gain amplifier with very low noise. All those carefully
chosen devices are placed on the printed circuit board by using the latest
CAD technology and star shaped mass technology. A power supply circuit
supplies the sensitive amplifier circuit with filtered direct current. Our
output is an extremely fast Single ended Class-A Mosfet output stage with
very low output impedance to drive any cable on the market to make sure the
signal is transported to your amp no matter which cable you use in highest
perfection
All this is put into a rock solid housing milled out of a block Aluminum.
This nonmagnetic housing is part of the shielding and ensures perfect sound
quality.
Technical Data and Dimensions:
Dimension: BxWxH 190x165x50mm
Weight: 3kg
Gain: 41dB forMM, 57dB for MC, and 69dB for MC-low
selectable by the front knob.

With the Tango Mk3, we created a mid price phono preamp that is easy to
use and produces outstanding sound quality. The mainboard is manufactured as
a double-sided board with a large shielding surface on the top. Only with
the double-sided layout those short signal paths are possible which are
needed for the perfect amplification of the extremely small cartridge
signals. This guarantees very low hum and noise values and an outstanding
sound quality. MM and MC settings are widely selectable. We only use the
best quality capacitors on the market.
All electrolytic capacitors are bypassed with Foil-capacitors to make sure
small and fast impulses are transmitted in the best way. The allowed
tolerance from the RIAA curve is less than 0.2 dB. This is reached by using
1% resistors and high-precise 1% tolerance capacitors. The Tango also has a
subsonic filter which eliminates extreme low frequency distortions under 6
Hz. The technical data corresponds to the enormous effort we have used in
designing this phono preamp. Gain is 40dB for MM and 67 dB for MC.
