Review: Absolutely worth it! - This amp/DAC is extremely compact yet packed with features. The built-in 10-band parametric EQ (PEQ) is a game-changer for those who like to fine-tune their headphones. It also includes several preloaded EQ presets, including those from Oratory1990, making it even more versatile. I use it with my Arya Stealth and ZMF Bokeh, and it provides ample power to drive both. However, when using EQ with a negative preamp gain, I do need to maximize the volume to reach my normal listening level. Overall, very happy with the purchase - highly recommended.
Review: Perfect in every way. - Omg! The software just makes it worth every penny! Very professional.

## Questions & Answers

**Q: Does computer supply power thru usb when it works as dac or it work on battery power?**

**Q: Can i get full benefit of apple music lossless tracks on iphone 12?**
A: Yes, as long as you use this as a wired connection and with headphones that can reasonably play 16bit/44.1hz quality. Things to keep in mind: 1) The headphone is as good as the DAC, and vice versa. 2) Bluetooth is never really "lossless," but you can get approximates that are likely to fool your ears and thus be the same thing. Using the Qudelix as a bluetooth DAC will not give you "lossless" music output, but it will be very, very good. If you want true "lossless," you have to be wired. 3) On Apple devices, be sure to enable lossless output in Settings for iPad/iOS, or Music preferences AND in the MIDI launcher on Mac. Happy listening!

**Q: How can I pair this divice to a wireless earphones?**
A: It is not made FOR bluetooth earphones—IT IS A BLUETOOTH device itself!  Just plug in wired earphones & they ARE NOW Wireless Earphones when Quedlix 5 is paired with an audio source!

**Q: Is it possible to connect this to a pc via usb, then have the dac stream music to a bt headphone?**
A: Only if the BT headphone can be connected with a cable to the headphones.  Some BT headphones have a jack for a wired connection.
