Transcripts
hi guys today I wanted to tell you about
uh a new acam pd5 uh USB dongle USB
dongle meaning uh headphone amplifier
and digital to analog converter in one
uh I got it because I was very
interested about the performance of the
AK 443 SQ um digital to analog converter
inside because this is unit that's
mostly found in uh bigger desktop
digital to analog converters so I was
very curious how does it perform in such
a small device um this is uh something
produced by acam you can get this
headphone amplifier in silver or black I
got the Black Version because uh black
is a classic color for me uh okay so
it's quite
small as you can see we have gain
selector and gain selector also doubles
as a playback control button uh one push
push will be stop and play uh two pushes
will be next and three pushes will be
previous song and we also have volume
controls uh here and these are physical
buttons they are quite nice uh we have
this uh nice small window here and this
window uh will show us not only the
digital to analog converter chipset but
but there's also an LED diode inside
let's connect it to my
R4 and we should be able to see par off
okay so so we won't see that so
anyway uh a few important things about
the Box contents I don't usually do
unboxing videos uh but this time uh
there's something important about the
Box contents uh together with the device
you're getting a USB
c2a
converter uh so you can connect this to
your PC and use use this as a digital to
and headphone amplifier uh for your
personal computer but the important
thing is that you're also getting this
small high quality USB to us USBC to
USBC cable it's nicely braided uh why uh
is this important this is an important
thing because USBC connector here is a
little bit recessed as you can see so
when you're connecting USB cable it's
quite important that the recess will
match the plug of the
cable if your USBC cable plug will be
bigger it won't fit the assess here so
it may be hard to connect the device
with third party cables uh in most cases
it will work but since you're getting
such a nice Cable in the Box why won't
you use it uh okay uh the device has two
outputs the first one is singleand at
3.5 mm output and the second one is 4.4
mm balanced output uh most of my testing
was done with uh balanced output uh I
was uh testing this uh nice little
device with all my plan out headphones
uh meaning uh KZ pr3 uh K Symphony
high-fi man area and highi man and
Ananda Nano um and leure S12 Pro uh I've
also use some other headphones but uh
these were the most important ones
because uh these are giving me the best
sound quality and uh they have different
requirements uh when it comes to uh um
Power of the output uh from the
amplifier uh
so I've told you about the cables I've
told you about the converter uh for my
testing I was using uh Spotify from my
phone and I was also using Neutron
player with direct USB uh digital to
analog converter access from my uh highb
A4 I was also using air4
alone uh uh to power this device uh and
I was using uh my notebook I was using
my notebook as the last source and my
notebook uh was um playing my songs with
Fubar okay so the device uh has a nice
quality build it's made of
metal the front panel here is made from
translucent plexiglass uh or glass it's
hard to tell uh and it has a nice status
diode hidden in here uh I don't know you
should be able to see the small pattern
here and let's try to power this pattern
up this is basically a stopus LED but
the thing is that it's very neatly
hidden underneath I have no idea how how
they've done that if these are actual
holes now we need power on
will it power on yes it power is on yeah
can you see
that I love that because it looks very
nice and it's completely lost when
powered off you don't even see that
there's a status somewhere
hidden okay the most important thing is
as usual how does it
sound uh I was interested as I told you
earlier uh in this device because as
because of Asahi Cass chipset Asahi Cass
digital to analog convertors uh are
usually uh a little bit warm but they
are very detailed and they have this
amazing quality of the voices and this
was something that I was expecting to
expecting to hear here and I wasn't
wrong uh it's uh very musical uh it's
very melodic uh and all all the nice
detail is still here uh the bus the bus
has the very good textures uh it goes
really low uh it was actually one of the
best PIR rings that I got uh with my uh
KZ pr3 uh pr3 are uh planners uh
produced by KZ uh they are single driver
planners these are not hybrids uh so
usually the bus on them is very PR size
but it doesn't go really low with uh
this one with akam pd5 uh pr3 were
driven uh very well and all of the base
was dir and had very nice
textures uh the next the next uh
Ms uh as I've already told uh this
device gives you very natural a very
nice sounding uh Ms uh meaning that the
human want voices that vocals that
female vocals that male vocals will be a
very good and uh and very natural uh it
doesn't sound digital at all it sounds
very analog very nice uh and it has this
uh amazing voice quality of the bigger
desktop digital to analog converters
based on Asahi Cas
devices um leaving means behind and
going into trouble uh we have nice very
well extended Trel with a big amount of
detail and
transparency uh the interesting thing
here is that uh travel is not sterile I
mean um you can clearly hear the
difference between a sahi Cay device
like this one and Es saber chipsets uh
it's it's not that either one of them is
bad they are just different so you have
to find your own flavor and sometimes uh
you'd like to have both of them because
for some music for some songs aaki Cay
will be better especially for acoustic
musics uh music but sometimes you'd like
to hear um this this very analytic
trouble of cyber
device okay so this a gives this very
transparent feeling and this translates
to very good separation of all
instruments uh The Sound Stage is really
good it's quite holographic uh since I
was testing this with headphones I won't
tell you that it extends very well in
all directions uh but uh for the
headphones it's a very good stereo
graphic and holographic Imaging that we
that we got with acam
pd5 uh okay what else uh
I think because you know uh I've been
reviewing tan gim space uh a couple of
months ago uh and compared to tanim uh
this device has better layering uh so
what why I mean what I mean by that is
that if you have for example classical
music on some or some small embl music
you can clearly hear that some of the
instruments are in the back and some of
the instruments are in the front so you
have these layers of Music clearly uh
visible actually hearable you can hear
them very
well uh then another interesting thing
and maybe the most important thing about
this device it's a very rhythmic device
uh when you're listening to your music
uh you want to tap your foot it makes
you enjoy the music it makes you feel
the rhythm it makes you uh want to Lose
Yourself into losing the music and
that's actually what happened what I was
when I was um listening uh to this
device during my critical review session
uh it should be about 1 hour but I
finished that about 5 hours later
because most of the time I was not only
listening and taking notes but just
switching my songs listening to my music
and spending quality time with my
headphones and with aam pd5 uh
the other important thing is that it's
although it's very Musical and it's in a
way very easygoing it's also very
Dynamic and very precise meaning that it
won't cover up the bad things in your
music if the recording has a bad quality
if the recording have has some flows uh
production flows uh you will be able to
hear it all um it won't completely dist
destroy your musical experience but you
still will hear all the bad things that
are in the recording which in my book is
uh very good because I want my devices
to be transparent precise and musical if
the song was recorded badly then let it
be it was recorded badly it will be bad
when listening
to okay uh another interesting thing uh
here is that uh as I've told you at the
beginning I was testing this device also
with my uh big planners with my high-fi
man uh lineup and this small fry was
able to drive properly highi man area
although I had to switch the G to high
but it was working fine it wasn't very
warm when used for a long time uh so
it's very efficient uh when using the
power from your phone or from your
digital to analog player and it was able
to drive
areas uh which is a good thing in my
book I wasn't expecting that but the
area when where this excels uh is
driving your
items uh it's
uh very Noise free if you know what I
mean uh it has completely black
background no his or
whatsoever Nothing Hurt with any of my
IMS so very quiet very clear black
background and uh very good sound
quality very transparent very Dynamic
and very very natural when it comes to
vocals so I think for now it will be my
reference USB uh device um the last
thing is uh you're probably wondering
about the price of this device and the
good news is that you can get this for
$79 and that's without any coupons or
without any sale cleanes that you can
get uh on Ali so you'll probably will be
able to get it even cheaper but for
$39 it's absolutely brilliant I wasn't
expecting that kind uh of uh quality
sound from such a small device and I
wasn't sure if it will be better than
tangim but it is it's better it has
better sound quality uh it has uh two
gain levels uh it's as small as t gy uh
and all in all I like it very much uh I
will give the links uh in the
description uh of the video to the shop
that I got this one from uh so you can
check the current
price uh okay ask me anything I could
probably forget forgot to sorry ask me
anything I probably forgot uh in the
comments
section and one more parting view on the
device as I said it's very well
made it's light but it gives you this
sturdy feeling in your hand
thank you I hope you enjoy this video
and see you next
time yes you thought that was the end of
the video and I also thought that's the
end of the video but after reviewing
what I've recorded I've decided to add
some more information uh about this
small but beautiful device uh the first
one is that uh it does DSD and it it
does DSD up to DSD uh
512 so it's very very good uh the
sampling frequency that this device
supports is up to 778 khz so also top uh
of the uh shelf
device uh but what's uh the most
important thing here is that signal to
no noise radio is 125 DB I haven't
mentioned this area because usually I
don't talk about
because you can check them on the
manufacturers page but
125 DB uh signal to noise ratio is
state-ofthe-art uh the same goes for for
THD plus noise so total harmonic
Distortion and noise uh have less than
115 DB that's amazing uh if you ask me
uh what else can be interesting for some
of you guys is that you're able to
access and change the uh filters that AK
for for 93 uh integrates uh you can
change between six filters provided by
the digital to analog converter you're
switching the filters by pressing this
volume keys together and holding them
for a couple of seconds and you have six
filters to choose from the default one
is short delay sharp rolloff which is
basically my favorite in uh all of the
devices all of the um digital to analog
converters I use and but you can also
change it to sharper rolloff or short
delay slower rollof or just slow rollof
or super slow rollof of just low
dispersion short delay but the best for
me giving the most detailed and fast
sound is sharp roll sharp roll off and
short delay
uh another interesting thing uh for PC
users here is that you can actually
download AO drivers for this device and
uh you can switch uh USB access modes uh
you can access you can use this device
in USB 1.0 mode or you can change the
operating mode of the device uh for USB
2.0 mode uh but uh with default settings
it's ready to use use with the best in
my opinion with the best uh set of
settings so USB Point 2.0 and uh sharp
uh
rollof uh short delay
filter uh so I forgot about these things
because I've set them I checked if I can
change them and I've left them uh on
default positions uh when I started to
listen to the device but that's quite
important because uh because of two
things the first one is uh I don't
really know another device like that
that would allow you to actually change
the filters uh usually the producer the
manufacturer chooses one of the
available filters and set it sets it as
a default and you cannot do anything
about it and the other thing is that uh
in USB 1.0 mode it'll be compatible with
all operating systems uh out of the box
however it will be limited to uh 96 uh
Kilz um uh for the uh sampling frequency
uh but in USB 2.0 mode it'll work like a
fully blown desktop digital to analog
converter okay so once again thank you
and uh ask me anything I could again
forgot in the comments
section highly recommended highly
recommend that it will be my daily
driver and and my main testing device
for IMS from now on bye guys
