    Tiny audio genie

    I wanted a small dac dongle with good audio output. I was surprised when I first listened through. Its output is sparkly with digital hifi like output. Bass is good. Voices are clear. Decent staging. Treble is good but may cause sibilence in high treble tuned earphones. Planar like CCA Pla13 are decently drived. Power output is better than other dongles in this price. Dont consider them as replacement for 5k or 10K dongles/usb dacs but for price they are really good. Build quality is good. Biggest con I could find is only 3 months warranty. Increase price to 1.1k and provide atleast 1year or 6 months warranty.

    Beginner's DAC-AMP, value for money

    I have never used a DAC-AMP before and I was in a shoestring budget. I even did not know whether it will be a good option or not as an add on to my mobile phone audio player. My Laptop has a poor sound output quality, not the volume,but the character of the sound. Adding a separately purchased USB -A to type C converter, I was amazed to the change it made to the sound quality and volume. 40% of laptop volume was more than required. I wonder,why such a small chip cannot be included in a laptop to enhance sound. I use a basic, inexpensive over the ear headphone, probably of 32 ohms rating.With my mobile, the sound improved(clarity,volume, frequency separation) definitely, but not to the extent that was there with my laptop. Sound clarity improved significantly for such a small dongle. As I cannot compare it with more expensive DACs, I do not know, how they will perform, but I am satisfied with this and I think it to be a real value for money product. It came with a hard,fibre clad box as well but the only downside I think was the failure to provide a basic USB-A to type C converter that is essential to attach it to the laptop. It is just the reverse of usual OTG dongles that is available everywhere, and it is a bit difficult to procure. No adapter for iOS was there as well.

    Thank you so much for taking the time to leave us this review.
