UNICO PRE is a versatile and fine - sounding preamplifier based on hybrid valve and mosfet technology. Although designed as the natural partner for Unison Research Unico DM dual mono power amplifier, it will give excellent results with virtually any good quality power amplifier.
Circuit Design
The fully solid-state input stage uses J-Fet technology, whilst line
level amplification is entrusted to three twin-triode valves. A phono
stage is built-in, which is also fully solid-state using low-noise op-amps
designed specially for audio use to give excellent performance on vinyl
replay.
RIAA equalisation is active for the low frequency band and passive for
the high frequency band.
The phono stage will cater for both MM and MC cartridges, including those
with low (i.e. less than o.5mV) output.
Balanced/Unbalanced Operation
For maximum flexibility of use, five unbalanced inputs are provided,
and three (line 2, 3 and 4) are also balanced. One pair of balanced outputs
is also provided, as well as two pairs of normal (unbalanced) outputs.
All connectors are gold plated to guarantee excellent contact surfaces
throughout the life of the product.
Controls
Unico Pre is supplied complete with radiowave remote control of volume,
activated by an elegant wood handset. Radio control is a convenient feature,
allowing distant operation even out of sight of the preamplifier if required.
The input selector is a high-quality unit, hermetically sealed with sliding
gold contact surfaces for silent operation and long life. The large power
on/off switch pad incorporates a soft back-lit multi-led display to provide
visual indication of status.
Unico Pre is also equipped with the same Link and Loop facilities of
Unico DM Power Amp, to enable remote switch-on and switch-off, activated
either by musical signal or by power-on from another unit in the chain
(see Unico DM characteristics for details of this feature).
Appearance Design
No Unison Research product would be complete without an attractive appearance
design.
Unico Pre is no exception, its understated elegance being enhanced by
machined stainless steel controls that are silky smooth in operation.
Its half case - width form means that Unico Pre can be placed side-by-side
with one or more Unico DM power amplifiers to give a high power yet compact
stereo or multi-channel set of outstanding sonic performance.

Ayre Acoustics C-5xe Universal Disk Player Stereophile Extract: "It ought to be fairly obvious that I found the Ayre C-5xe more than satisfactory. I didn't expect it to disappoint, but I was unprepared for just how much it delighted me. I've heard a lot of impressive audio components over the years, but I've heard very few that afforded me greater musical pleasure or sent me on as many voyages of musical discovery through discs I thought I knew well." - Wes Phillips, July, 2005 |
Gryphon Diablo The ultimate reference integrated amplifier at £6100. The Gryphon sonic magic in a reasonable sized and georgeous case, you must hear this as it puts most pre power combo's to shame, pure music at its best. |
Brinkmann LaGrange turntableThe Brinkmann LaGrange turntable is without a doubt the best source component I have ever had the chance to enjoy over an extended period of time. It represents a level of perfection and emotional connection to music that I have never heard before. - Danny Kaey extract from Positive Feedback |
Teac Esoteric DV-50SThe Esoteric DV-50 is the most fun you can have with digital music playback short of the dCS trio reviewed by Michael Fremer in April 2003 (Vol.26 No.4). Given that the dCS gear costs about six times as much as the DV-50, the Esoteric is a screaming bargain, especially considering its hyper-advanced technology, bulletproof build, and exceptional sound. You can even play movies on it. - Stereophile Extract |
