Sparkling highs that make music come to life, a sweet inviting midrange, full-bodied
palpable presence, and a rounded controlled bottom end are the hallmarks of the DAR’s
sound. The DAR’s controlled bass extension will produce satisfying, musical, bass
performance even when driving small stand mounted monitor speakers but will tame
the over loading often associated with larger woofer designs. All of these features
combine to present the listener with a true musical experience.
*Comes standard with wooden knobs. Stainless steel knobs additional cost option.
The DAR, a hybrid integrated amplifier with a 6SN7 tube at the input stage, produces
100 watts into 8 ohms and 150 watts into 4 ohms. The innovative design of the DAR
presents a number of technical firsts for Blue Circle Audio. It uses a "pancake"
style toroidal transformer that has high current, high power, and high-speed capacity
without the noise that is typically associated with transformer design. Its dual
power supply allows the tube and output stages to function independently for better
imaging and soundstage creation.
The DAR’s discrete circuitry creates smooth sparkling highs and a powerful-controlled
bottom end. The circuitry utilizes two ultra high power bi-polar transistors for
each channel to ensure that phase coherence is at its best . Our over sized heat
sink makes sure the output devices run at their best operating temperature. Everything
has been done to optimize the DAR’s performance.
*Shallco volume control and active gain stage additional cost options.
Most interestingly, the 6SN7 tube, seen in the following picture, is configured as
a unity gain at the input stage. This innovative design feature optimizes the 6SN7
to take full advantage of its sonic signature. The DAR s circuitry is so transparent,
it shows off the best of the 6SN7 and allows the seasoned audiophile to roll tubes
and fine-tune this exceptional design to their personal preference.
The DAR runs so cool that you can put it in a tight space. It needs a scant 5 inches
to breathe *. Its multiple protection circuits including DC offset, thermal overload,
and short circuit at the output make it safe and easy to use while driving the most
difficult loads to satisfying volumes. The DAR also includes a turn on muting delay
to avoid turn on transient noise.
This is only a partial listing of the many advantages that are at the heart of the
DAR s innovative design. To hear the sound of music bring your music to the Blue
Circle dealer nearest to you.
All parts used in the DAR are RoHS (lead free acceptance) compliant. The DAR uses
less energy than a 5 watt tube amp when it is at idle. When the power switch is off
the unit is completely disconnected from the power source and draws no power at all.
The high efficiency output stages waste very little energy and therefore generate
very little heat.
No matter which angle I used to dissect the DAR, its presentation managed to escape
tipping the scale to one extreme of the other. It always struck a happy balance between
distinguished character and "tell it like it is" transparency. Sean Fowler - Affordable$$Audio
