Caratteristiche:
Dalla forma classica , con un pannello in alluminio anodizzato di
alto spessore e u coperchio in lamiera , veramente pesante.
Nella parte anteriore oltre a i soliti comandi di accensione e selezione
entrata , che puo' essere sia coassiale che ottica , troviamo un
display con led a fosfori blu , che ci segnala sia l'entrata selezionata
che la frequenza di campionamento , che puo' variare da 44.1 a 96 kHz.
Aprendo il coperchio superiore troviamo una coppia di valvole 6922
Helectro harmony , una coppia di trasformatori e una serie di
Condensatori di buonissima qualità Elna.

DAC 72 is the home station locates is HI END the DAC
basic product, simultaneously for 同系列 DAC in
with the family product DAC50 substitution type, many details already
passes through the improvement, the sound quality completely surmounts
the standard which DAC 50 achieved.
The chip uses the CD most flourishing time most to receive the high
praise PCM1702, with THETA DSP BASIC is the same product, this chip has
the stability, durable as well as the sound is exquisite, the analysis
strength higher merit.

DAC 72 may accept
44.1 kHz ~ the 96kHz signal. May accept
is equal to the DVD AUDIO quality, may completely and the present
most high-grade CD turntable perhaps the frequency hoist
coordination use.
On the line overhead construction, several parts select the 96kHz
receiver which at present most is worth trusting, the model are
CS8414 outside, matches sets at the high accuracy oscillator, causes
JITTER to fall to is lowest, guarantees the music purity.

Coordinates DF1704, finally sends in decoding chip PCM1702, the entire
machine design all uses in the market condition the highest quality
chip, the same specification similar product, the selling price at least
is above the DAC 72 several folds.
The analogy part is this machine kind another one brilliant place, first
is discards with inexpensive OP IC makes LPF (low pass filter), but uses
the vacuum tube to do outputs the part, completely avoids IC the
influence, also avoids using massively 負回授,
causes the detail losses. The line overhead construction makes SRPP by 2
6DJ8 to continue the output ultra, the output amplitude big, S/N
compared to extremely high, simultaneously has the low output impedance
characteristic, more important, the entire analogy signal output
completely is by succinct vacuum tube processing, completely does not
have any faint trace crystal perhaps the IC ingredient, guaranteed the
sound has most goes against and the equipment "is sweet, Run, slides, is
suitable" four major characteristics.
Except above, each kind of sound makes up the grade part is the case
everywhere. If ELNA precision ceramic FOR the AUDIO electrolysis
electric capacity, the DALE military discipline resistance and so on has
a fever the part, is slightest place all does not let off.
The power source supply is 大有文章, analogy and
adds on the electromagnetic screen with a several independent employment
high efficiency R transformer. Each chip all has an independence group
of power sources supplies line. The analogy part uses the precise
constant voltage control system, guarantees purely does not have
雜訊 the direct current supply.
Several inputs may provide group of coaxial inputs, group of optical
fibers inputs. The analogy part provides
group of RCA output terminal.
Engine case processing by the 10mm thick aluminum
kneading board, performs the surface anodic treatment, the sense of
reality is extremely high-level. The box body to the steel plate
makes, the intensity extremely high also the
quality is extremely heavy. The kneading board reveals 示數
the position signal input frequency as well as the input files position
by the blue color monitor, the blue light
demonstrated the curtain may make the shutting down movement.
Intends the step high progression position news source the fan movement
to have to be quick, similar high step chip like PCM1704, PCM63, PCM1702
all were a model which already suspended production, at present all
祇 has the few stocks to be possible to supply
to manufacture the DAC supply is the surface demand. Before is similar
to DAC 50, the chip uses up, immediately suspended production, intends
the friends which bought into surely don't again to hesitate, in order
to avoid regretted once more.[ Commercial

Come suona:
Direi che il prodotto e veramente ben riuscito , ottimo per tutti
quelli che cercano un suono piuttosto rotondo e avvolgente senza
perdere troppo nel dettaglio.
Consigliatissimo per i proprietari di macchine stupende come i Teac Vrds
o Philips o Sony serie ES , ma tanti altri , che dispongono di
meccaniche favolose , ma dal suono piuttosto asciutto e spigoloso.
