Once I laid eyes upon the Audio Space Mini Galaxy 1, I knew there was no way I'd turn down reviewing it. How could
anyone pass up quality time with this little gem? Hong Kong-based Audio Space is no here-today, gone-tomorrow
A
sian brand. These folks have been offering vacuum tube audio equipment for over 10 years and in the process, built
a solid rep in the Far East for quality and reliability. Still, they are relatively unknown in North America and Europe.
That should change. Audio Space has secured steady distribution in Canada and the US via Charisma Audio and Gini
Systems respectively. With the continuing stories of Asian grey market shenanigans, I can understand many Western
readers' reluctance to sample yet another Chinese brand. Upon accepting this assignment, I dutifully snooped around
the web and indeed, found a considerably cheaper knockoff of today's piece. When I broached the subject with
Canadian distributor Bernard Li, he informed me that various Chinese audio manufacturers are currently pursuing legal
action against this particular counterfeiter operation
. I have no idea how successful they will be considering China's
free-wheeling capitalist anarchy. But it is comforting to know that at least some Chinese firms are trying to deal with
these issue.
The Mini-Galaxy 1 is a diminutive two-chassis integrated loaded with features including headphone output, outboard
power supply, adjustable negative feedback and even a USB DAC. The Mini Galaxy 1 offers 12 watts of Ultralinear
Class A/B push-pull power per channel and can also function as a standalone headphone amp. It has inputs for two

sources and uses a separate power supply with a fairly substantial toroidal transformer. No plastic wall wart here. Tube
complement consists of a pair of 12AX7s and four EL84s. No periodic check-up of power tubes with a multi meter is
required with the auto biasing circuit. Internal wiring is point-to-point. The supplied tubes were of unknown origin but
sported Audio Space logos. However, the EL84s looked and sounded identical to a set of JJs I had on hand. The tiny
onboard DAC is built around a Burr Brown PCM 2702 44.1/48kHz chip which appears to be standard issue for most
inexpensive USB DACs. The manual is well laid out, informative and written in decent English.
The front panel has a pair of sturdy metal knobs for volume and negative feedback control. The rear panel of the amp
half contains gold-plated 5-way metal binding posts, the USB input, two sets of gold plated RCA inputs, headphone
output, power umbilical connection and a small toggle for source selection. Power up is via the power supply’s front-
mounted knob. A 450mm locking umbilical links the amp to the power supply which itself gets connected to the wall
outlet via the rear-mounted IEC and included AC cable. Dimensions are 165mm x 125mm x 210mm for the main unit
and 165mm x 65mm x 210mm for the power supply. Total weight for both modules is 6.5kg. Both were finished in an
understated yet attractive two-tone cream/grey finish. Completing this eye-catching feature-rich package was a pair of
extra fuses, a USB cable, cotton gloves and a lint-free dust cloth.
Build quality was excellent as with every Audio Space product I have thus seen and would probably embarrass not a
few more expensive products. No loose solder balls or flimsy controls or aberrant behavior. Apart from the rear panel
location of the source switch and headphone output, the Mini Galaxy was a joy to use. In fact, the rear switch was not
a concern due to the small size of the amp. So you need to reach a few inches around to change sources. Big deal.
A
fter sufficient warm up, the Mini Galaxy was fairly quiet electrically and mechanically. Up close there was a slight
hum, audible from the amp itself as well as through speakers and headphones. It didn't interfere when listening to

music but it was noticeable during silent passages and between tracks. I auditioned the Mini Galaxy first in my main
system and then in my bedroom for a little late-night Internet radio via headphones and laptop. Connecting my IBM to
the Mini Galaxy via the USB connection was dramatically superior to driving my headphones directly from the laptop.
What was thin and lightweight became significantly fuller and richer sounding.
Recent CD/LP acquisitions which have seen plenty of air time over the course of this review included a wildly quirky
yet utterly captivating 1971 live BBC performance of Mahler's Ninth conducted by the late avantgarde
composer/conductor Bruno Maderna [BBC Legends 4179-2]; a delightful Replacements retrospective [Rhino 70013];
Dylan's surprisingly good Modern Cool [Columbia 87606]; and Rudy Van Gelder's remaster of Eric Dolphy's smokin'
classic Out There [Prestige 8101].
Sonically, the Galaxy exhibited most of the characteristic signature of every EL 84 amp I've
heard to date: quick, incisive slightly lean bass, sparkling grain-free highs and a smooth
detailed midrange without any trace of bloat or excessive warmth. How it differed from my
EL84-equipped Manley Mahi monoblocks was in areas such as weight and frequency
extension. More on that anon.
A
s for the Galaxy's music-recreating abilities, don't let the puny size fool you. This little
hottie had no trouble filling my room with music. If you auditioned this amp blindfolded,
you'd undoubtedly guess you were listening to a bigger amp. The Galaxy was rhythmically
alive and -- providing I used the appropriate speakers -- thoroughly competent and
convincing. Rendering of spatial cues and instrumental timbre was better than expected.
Music was not projected forward of the speakers but more along their plane, with a decent
rendering of depth.
Tonal balance was open and neutral; that is, not too rich or warm nor overly cool or
analytical. The amp's presentation was crisp - detailed with enough immediacy and
coherence to maintain my attention.
Bass performance was more about quickness and timbre than weight or power. After all,
this is a quite small amp with limited power reserves. Don't expect to play AC/DC at 100dB
levels unless of course you own very sensitive speakers like Ed Schilling's Fostex 126E-
equipped Horns or Gemme's now discontinued Concerti 108, both of which played to
extremely high levels with the wee Audio Space. In fact and in many respects, I preferred
the Audio Space over my Manley separates when driving the aforementioned single-driver
speakers. While not as weighty and ballsy as the Californians, the smaller amp was a tad
smoother in the treble. I suspect the 4" Fostex drivers are a little peaky up high, hence my
preference for the Audio Space which conversely sounded slightly rolled off and reticent on
my highly revealing Green Mountain Audio Callistos. I suspect their 4-ohm impedance
additionally presented the Galaxy with a somewhat difficult load.
I heard more low-level resolution from the Manley trio which was also quicker, more incisive
and with tighter, fuller yet more controlled bass. There was also greater body, bloom and
rendering of space. At nearly four times the price and with substantially more robust power supplies, this came as no
surprise but was still heart-warming. More money doesn't always buy better sound after all.

The adjustable negative feedback control -- like that of the Manley Mahi I reviewed a few moons ago -- simply gave me
greater influence on the sonic presentation of each recording. Think of it as a presence adjuster that pushes back or
pulls forward the entire sound picture. Dial up more feedback and everything shifts back several rows with each detent.
Subjective volume decreases as well of course. Therefore, turn up the wick as you increase feedback and down while
reducing it. This feature proved ideal in taming overly hot or excessively in-yer-face recordings - as well as injecting a
little zing into reticent or distant-sounding ones. Overall and regardless of speakers used, I preferred the normal or
middle setting. It offered the best of both worlds. There is no right or wrong position. It depends on the material you
play, your partnering equipment and preference.
The Mini Galaxy 1 got most of the important aspects I look for in a component right and while there were caveats in
terms of weight, extension and self noise, it never failed to entertain. As a bedroom system with headphones or easy
speaker loads, the Galaxy would be an ideal choice.
My only issue with the Mini Galaxy is price in relation to its line mates. For $400 more, Audio Space's larger AS-3i
integrated offers more than twice the output power, triode switching, an additional input and the convenience of front-
mounted source selection and headphone output. Mind you, it doesn't have a DAC but I suspect most users would
already own a standalone CDP or transport/DAC combo. I admit that $1200 Canadian for a testicularly challenged --
albeit attractive and full-featured entry-level tube integrated -- seems a tad high but I doubt Audio Space had the
budding budget punter in mind with the Galaxy. I suspect the Mini's target are folks looking for a small, portable yet
high-quality second system. Perhaps then, the asking price doesn't seem out of place. While there are other entry-level
tube integrateds like the Dareds and Fatmans that sell for under $1000, none that I'm aware of share the Mini Galaxy's
build quality or flexibility.

A
s with any low-rated amp of limited power reserves, proper speaker selection is critical. I'd stick to small two-ways or
single-driver designs with sensitivity ratings over 90dB and at least an 8-ohm impedance. I don't think anyone in their
right mind would attempt to drive a pair of B&W 801s with this little amp.
The Audio Space Mini Galaxy 1 is an attractive, well-built, charming little music maker that would be ideal for a second
system in the bedroom, office or cottage. It sounds good and looks even better. Even the missus will approve.
