Ive been wanting to use studio monitors as home theater speakers for a while. Once I realized my TV had optical out and this DAC has optical in I instantly bought it. It seems to not color the sound and has a clean signal.The volume knob is smooth.The Bluetooth feature is very useful and sounds good.Throw away the optional they send you.Very easy to set up and use.

When we moved into our new apartment and I introduced the idea of "everything should work with everything" to my wife. She had one stipulation: get rid of the wires, even if that meant getting rid of my beautiful NAD 7225 stereo receiver from 1988. GASP! As it turns out, I had nothing to worry about.I discovered a tiny Bluetooth receiver to connect, using RCA cables, to my old amplifier. Now it was black in play. I found a tiny Bluetooth transmitter to connect to my Roku clicker via mini-plug to transmit to my stereo set. Computers and phones all have onboard Bluetooth capability, and therefore access to the amplifier. However, the challenge turned out to be the broadcasts I was receiving through my DTTV digital antenna connected to my plasma HDTV, which I also won't give up. The input into the TV is via a coaxial port. You see, back in 2005, congress allowed broadcast stations to drop the analog signals they had been sending for free through the airwaves since the 1940s. However, they would have to replace those with free digital versions, daily broadcasts of their one flagship channel, which they had to make available, for free, to anyone using a DTTV antenna. I use the "Antop Mini Big Boy" I got here. Using that rig, I saw every Olympic event I cared to on NBC, for free, in digital quality. The problem is that the only sound output from my old plasma HDTV is through an optical port. I hooked it up to the optical input port on the back of this thing and got...nothing. Turns out that when the input is from "digital antenna," the sound output from the optical port is in "PCM" format (whatever that is). For whatever reason, this thing can't handle PCM. To make the optical input work, you need to convert the TV's optical digital sound to analog (try the PROZOR 192Khz Digital to Analog Audio Converter), then into this transmitter, which I assume converts it back to digital, before transmitting it via Bluetooth. It's working very well with a couple of drawbacks. Using this rig, I can only change the volume at the stereo amplifier and not any of the remotes. You'll have to get up off the couch now and then. A collateral benefit is that any sound coming through the TV will be sent to the stereo amplifier, whether from the digital antenna, the DVD or the Roku box. While you can attach a Bluetooth transmitter to the Roku remote, directly, and in that configuration adjust the volume using the remote buttons and never get up, we almost never use it that way. That's because the sound coming through the stereo is so much richer and truer than from the TV's on-board speakers, we don't have to make it loud to hear everything, perfectly, clearly, and at a reasonable volume. We use the closed captions much less frequently, too. The second draw back is that having to use this two device system, converting digital to analog, back to digital again and then transmitting it, I suspect there's an increase in lag time. This means if I stare at the screen like a hawk, without blinking, I think the lip synch is not quite as good. My wife says she doesn't notice a thing, and, that's what really counts. What counts, for me, is that I get to see ballgames I can't get through Roku with HBO and Amazon, which is what we have. We get to see the old movies that are always on broadcast television, all kinds of playoff games, and every kind of award show. And all of this with beautiful sound and completely free.

Suite différents essais, correspond bien à mes attentes, surtout que le prochain TV n aura pas de prise CASQUE JACK 3.5 , je n ai pas d autre solution que de passer par ce miraculeux petit adaptateur

I was skeptical because I had an issue with the sound quality of a similar product and sent that one back. But this one, Amazing! Easy set up, great sound quality and Bluetooth connects easily and works even better! Took me a while to find the right product, but I’m very pleased I finally found this one!

Don't listen to the haters. I bought this wireless dac receiver and it is a great value. First, the build quality is very excellent. It is encase in a steel metal case that is a precised fit. It is not made out of plastic. Second, I opened up the case and looked at the board. It is clean and the soldering is clean. Really well done. Third, the range and distance of connection is fantastic. It doesn't drop when you are 40 feet away with walls in between!!! Four, there is volume control. It's through your phone or computer. Five, it connects right away and there is no fuss. Six, the sound is clear. I hear no distortions or anything bad. The music is clear. For $29 it is a great deal. This is a great solid package that fits in the palm your hand that allows you to stream music from tidal, Spotify, YouTube music to your stereo. You can hook this up to an amplifier and this unit becomes your wireless receiver, streamer, dac and preamplifier. All for $30. But I have this unit connected to my preamplifier and it works great.

Normal quality item,

nachdem 12V meinem alten PROZOR nicht gut bekommen sind und BT. ein Handy weniger beansprucht, hab ich mir das aktuelle Gerät gekauft und muss sagen - schon nach den ersten Tönen...der is besser, klingt blitzsauber, knackig..null Störgeräusche, läuft absolut stabil kurz....Saugut für nur ca. 43Eus., das wirklich Neue sind die Sendequalitäten, die ich allerdings noch nicht überprüfen kann mangels KH.Es können gleichzeitig Zwei BT.fähige Kopfhörer angesteuert werden, die Decodierung von 5.1 ist aber weiterhin nicht möglich...muss auch nicht. Wie gehabt lassen sich zwei digitale Quellen anschliessen, einmal via Optisch und einmal Koaxial/Cinch. ob nun TV-Box oder Konsole...egal.Was gerade anliegt wird mittels MiniLEDs auf der Front angezeigt, die können im Dunkeln allerdings schon nerven...abkleben. Die Reichweite ist Top, geht auch durch 3 Wände. Ein Netzteil ist leider nicht dabei, so ist das aber bei solchen Geräten üblich. Ein optisches und ein Usb-Netzkabel liegen bei...normales Handyladedingsbums a 5V reicht, haben die fast alle...aber besser gucken. Je nach Verwendung hat vielleicht das Endgerät einen Usb-Port, den kann man natürlich dann auch benutzen. Kleiner Vorteil, denn das Ding hat keinen Netzschalter, ist also Immer an. Mir ist das wurscht weil...läuft eh immer, aber manchen stört sowas.Fazit - im direkten Vergleich zu einer Usb-Verbindung über meinen DacMagicPlus...man merkt es ist Bluetooth aber mehr nicht, klingt akurat...tendenziell schlank, ich brauche jedenfalls Nicht mehr. 👍 Testgeräte und Zuspieler Samsung S20/A50, HuaweiP10

Acquistato per ascoltare in cuffia partendo da un collegamento ottico da Tv LG. Livello sonoro di buon livello e soprattutto regolabile sia usando una cuffia collegata con cavetto sia con collegamento bluetooth. Un DAC completo e versatile dotato di una qualità del suono ottima e esteticamente molto riuscito. Manuale anche in italiano. Rapporto versatilità/prezzo imbattibile: consigliatissimo! Mario

This review is updated below. I bought this DAC not expecting too much. I just wanted a "something cheap, good for now" solution. Mainly I wanted something that would allow me to play songs on my phone (non-aptX / non-aptX HD) through my pre-amp without it being tethered with an audio cable. It does this, but it could do it better.The RCA line out connection does NOT provide a true line level signal. Far from it in fact. If the RCA outputs were UPSTREAM of the volume control and provided a TRUE line level output I would've given this 4 stars. Even with the unit's volume control cranked all the way up I still have to crank up my pre-amp's volume knob quite a bit.Hooked up to my CD player through the coax input, I wasn't expecting it to sound better than my CD player's built in DAC (Denon DCM-460)...and it doesn't. Still, it would've been a pleasant surprise if it did. Part of the problem could be that the volume control is sucking tone? Admittedly I was using an el cheapo coax cable, but still it should've come close I would imagine, but it didn't.All in all it does what it's supposed to do, does it cheaply and does it okay. Design the RCA outputs to be upstream of the volume control and provide a true line level out at the RCA and it would be a 4 star review.UPDATE 5/3/19: The seller reached out to me and offered to send an improved replacement. After receiving it I did notice an improvement in the volume level when hooked up to my preamp through the RCA connectors. The earlier version I purchased required me to turn the volume knob up to near or at 0db on the digital volume display. The newer version plays between -20db to -15db. CDs played through the preamp typically play at around -20db to -25db so this newer version is very much closer to a line level output through the RCA connectors.Also of note I replaced the cable running from the Proster bluetooth receiver DAC with a slightly better cable and that helped improve the sound coming out of it. In the near future I plan on replacing that cable with an even better cable.I did still mention to the manufacturer that perhaps in a future update of the BT receiver DAC that they make the RCA connectors upstream from the volume control to provide a true line level and improve the sound coming out of the RCA connectors.Comparing this DAC to the CD player's onboard DAC is a bit unfair since the cable running from the S/PDIF out at the CD player is not very good and the cables running from the Proster DAC (better generic ones) to the preamp isn't nearly as good as the ones running from the CD player to the preamp (solid silver core). When I upgrade the cables for the Proster DAC I'll post an update. But, as of this moment playing CDs through the Proster DAC is not as good as playing them through the CD's DAC.Because of Proster's attention to improving their product I'm going from 3 stars to 4. It's nice to see manufacturers wanting to respond to their customer's concerns and improve the product. The new version they sent me is a noticeable improvment.
