PROZOR 192KHz Digital to Analog Audio Converter Optical to RCA Adapter Upgrade Volume Adjustable DAC with Optical Cable, SPDIF TOSLINK to Stereo L/R & 3.5mm Jack Converters

I wanted to hook up a pair of Bose headphones to a Samsung TV, which has no headphone jack. This device works very well and I can now watch DVDs with much better sound quality than I had ever heard before. I also got a splitter and two long cables, so two can watch and listen at once. The sound level is also adjustable using the control knob on the device (the TV remote sound level button does not work when the optical sound output is in use).

Bedroom TV Coax out to the Prozor 192KHz Digital to Analog converter. Out of the converter thru an AtNeDcVh RCA 4-Way switch into an old Aiwa all in one bookshelf stereo. It just worked. The volume control allowed matching the volume to a Bluetooth receiver also connected to the RCA switch.

Works very well. The last one worked for about 2 years before I started getting static from the left channel. This one is an upgrade to the last one. Same company.

Awesome - works a treat! I'm not an audiophile, but have been an avid listener to an eclectic mix of music for 40+ years and have owned moderately high-end gear for many years: Cary tube amps, Cary tube preamp, Klipsch Cornwall speakers, NHT tower speakers, Arcam integrated amp, Audio Control Pantages amp, Golden Tube amp, B&O turntable, etc. Recently, I downsized my audio equipment and now mainly just listen to music from my desktop PC played through near-field Kef Q300 bookshelfs powered by the Pantages amp. I needed an external DAC that could accept a Toslink input and found the Prozor on Amazon and gave it a shot. I have been totally amazed at how well this unit works and especially sounds! Had originally planned this would just be a bridge device until I could research a higher end unit, but its performance has me rethinking my strategy - certainly in no hurry to replace it with anything 20 times more expensive. I know from past experience, I won't come close to receiving 20 times better sound. Besides the amazing detail produced in the data stream, the best thing about the Prozor is its invisibility - no sound is created by the device when nothing is being fed it. And, the volume control and headphone jack are gravy on this well-engineered metal cased unit.I have only had this unit for a few weeks and initially, I was going to send it back. It doesn't come with a power supply and I plugged the supplied USB cable into a USB 2 port on my PC and immediately got this very annoying low-level hum when no music was being played. The hum disappeared when the USB cable was unplugged, which pretty much confirmed it was coming from the Prozor. Fortunately, I eventually plugged it into a newly installed USB 3 port and was happily greeted by total silence. Its been silent ever since as long as it's plugged into a USB 3 port and not a USB 2 port. Strange, but absolutely true.Most audio reviews always include a qualifier stating how well the device being reviewed performs given its price level. No such qualifier needed for the Prozor - great sound - period!

I recently purchased a new TV (a 2015 Samsung LED) after my old TV kicked the bucket (requiescat in pace, friend). All was well and good until a week ago when I wanted to play video games late in the evening. I had decided to use headphones as I didn't want the noise notifying the humans in the neighboring apartment of my awesome gaming skills and their attendant coolness. It only breeds jealousy and contempt, you see. Anyway, to my surprise the new TV did not have a headphone jack. It did, however, have a digital optical output--you know, for all those digital optical headphones that exist and which everyone has...And so, with modern technology being so awesome, giving us more options, and generally making life easier, I went and picked up the necessary DAC (not this one) so as to operate this peculiar and archaic device known as the headphone. Which... didn't work. I mean, technically it worked, but there was no way to control the volume once External Speaker was selected in the TV sound options, and my headphones don't have a volume control, so the volume was limited. The neighbors would just have to deal with my coolness for the time being...Then I bought this thing, which DOES have volume control. And it all works great. Except for one thing: this little box is so good at converting things that it also converts the left audio into right audio and vice versa. This means that audio cues in a game (gunfire, fe) come from the wrong direction. I believe another reviewer also mentioned the same thing. Perhaps it is defective, though I suspect they are all like this. I solved this issue by wearing my headphones the wrong way (they're actually more comfortable that way as the cable no longer crosses my body or gets in the way) but it is something to bear in mind. Overall I am happy with this product and would rate it five stars were it not for this issue, which, as I said, for my purposes isn't really a problem.

Great converter. Works perfectly.
