Descrizione

[From the ARC website]

The VT100 is a new all-tube, balanced stereo power amplifier that draws upon the advanced technology of the flagship Reference Series models. Rated at 100 watts continuous output per channel, the VT100 is a Class AB, differential circuit design using two matched pair of 6550 output tubes in each channel, along with four 6922 twin triodes per channel for input and driver stages. A fully regulated, 270-joule power supply is distributed between two separate, isolated output circuit boards for short signal paths and true “dual mono” operation back to the massive main power transformer. Constant-current sources in the input stage help maintain stable drive characteristics and differential balance under the dynamic conditions of music reproduction.

Ultralinear output transformers and partial cathode coupling to the output terminals give the VT100 higher efficiency and lower output impedance than conventional designs for better drive into a wide variety of loudspeaker loads. Inputs include both single ended and balanced. Output terminals are custom-machined, heavy duty, gold-over-brass posts. A spacious chassis and open internal architecture allow ample convection cooling without fans.

POWER OUTPUT
100 watts minimum continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 100 watts, below .05% at 1 watt. Approximate actual power available at “clipping”: 110 watts(1kHz) (Note that the actual RMS power output is dependent upon both line voltage and “condition” ie: 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) 15Hz to 80kHz.
FREQUENCY RESPONSE
(-3dB points at 1 watt) 1Hz to 100 kHz.
INPUT SENSITIVITY
1.9V RMS (Bal or SE) for rated output. (23.5 dB gain into 8 ohms.).
INPUT IMPEDANCE
200K ohms Balanced, 100K ohms Single-ended.
OUTPUT TAPS
8 ohms, 4 ohms
OUTPUT REGULATION
Approximately 0.8dB 8 ohm load to open circuit
OVERALL NEGATIVE FEEDBACK
10dB.
DAMPING FACTOR
Approximately 11
DISTORTION
1kHz total harmonic distortion typically 1% at 100 watts, below .05% at 1 watt
SLEW RATE
15 Volts/µs.
RISE TIME
3 µs.
HUM & NOISE
Less than 0.5mV RMS – 95dB below rated output (IHF weighted, input shorted).
TUBE COMPLEMENT
VT100: (4 matched pairs) 6550 power output, (8) 6922. 
DIMENSIONS
19″ (48.3 cm) W x 8 ¾” (22.2 cm) H x 19½” (49.5 cm) D. Handles extend 1½” (3.8 cm) forward

Titolo

Consonance Srl

Ricordo da bambino zia Maria a casa della nonna suonare con il Petrov Pianofortissimo di Carosone, un brano da virtuosi che lei eseguiva con naturalezza. L’idea di riprodurre la musica dal vivo in un luogo protetto come la casa di mia nonna mi ha spinto a fare di questa passione il mio lavoro. A 14 anni andai per la prima volta in un negozio di dischi, chiesi i Police e ascoltai Bring On The Night in un “Pioneer A400”: fu un momento indimenticabile, un rituale di iniziazione… Da qui è nata la mia passione: all’istituto agrario passavo ore tra i banchi di scuola ad immaginare come potesse suonare quel pezzo strappalacrime di Tracy Chapman, Baby can I hold you, con le casse di ultima generazione Yamaha. L’adolescenza l’ho passata costruendo o riparando amplificatori Marantz che trovavamo a casa di amici e parenti.A un certo punto con mio padre decidemmo di creare Consonance, per coniugare questa passione con il lavoro: e sono passati quasi 30 anni dal fatidico 21 aprile del 1991, quando aprimmo il primo negozio.
