If you use this device then volume level decreases around 40%. But size, and all of device is good, durability is good. In terms of the output i dont recommend it. I am using it with my VU 65 inch tv along with the creative woofer system.
Excellent product very happy with it, using usb power from my sony amp and ive connected additional mixer for Karaoke mic and my Tewtross converter, and selected pcm on my smart tv ,And 1 more selection on smart tv that is sound output mode on Receiver HDMI now with all these connections your one and only one remote for smart tv works for everything, Speaking about Tewtross DAC audio output is crystal crisp clear,the most important is that any normal usb cable can power this DAC, i am so very pleased with the product, its been only a month may be next month i would be able to tell u about the durability, currently I've been using for not less than 3hours a day since 15days no heating issues like earlier i had pruthvik DAC which i had to replace once and after month it was dead ,i guess this lasts long. Overall i loved Tewtross DAC performance at fullest.
I have connected my TV to bose soundlink revolve speaker & it's working fine with very good sound quality. Very easy to setup & it comes with Aux & micro USB cable (which I have attached directly to my TV's USB port for power). Customer support is good & it comes with 1 yr warranty. Price is reasonable. So I would strongly recommend it.
There product does everything as specified. You just have to connect the optical cable from your source to the tewtross converter and use a 3.5mm aux cable to connect to your speaker system. There's no perceivable downgrade in the audio quality, but make sure you use good quality cables and a 10watt USB adapter or a fast charger. Conclusion: It's an useful converter to connect to a digital source to an analogue sound system.
Sound clarity is really good. It gets power from USB port. So no need of additional power source. You can connect to the USB port of TV itself, if TV doesnt have additional USB you can use Mobile charger.
