Qudelix 5K Reference DAC AMP

Product Information

With 4V RMS on tap from the balanced headphone output, the Qudelix 5K can run pretty much every earphone and a lot of sensitive headphones like the Sennheiser HD660S. As an example you can choose the FiiO FH9 for a cinematic and bass shaking experience or switch to the Sennheiser HD660S for classical music listening like Yuja Wang's latest album. Simply by pausing one source and resuming the other, it is sufficient to switch the audio from each source.

Regardless of their purpose or inner hardware components, from audio players, wired or wireless USB amp/DAC, they tend to present a more or less neutral and uncolored sound.The Parametric EQ is always much more complex and requires some knowledge and time to use but allows a more precise customization of the sound. One small criticism here is that it doesn't seem to work if there's no music playing through the headphones - this is a small minus, and Qudelix should add the feature to always keep the transparency enabled, even if no music is playing - it can be very helpful.

The key difference between them is in the embedded equalizer, the BTR5 has a simple 10-band one which is only effective in Bluetooth where the 5K has the best and most configurable equalizer which is also effective in USB mode. net/Products/LDAC/ We, Qudelix, have developed the LDAC library for QCC512x by ourselves, upon the official technical partnership contract between SONY and Qudelix. The embedded DSP cores perform double-precision 64-bit EQ processing, providing the most accurate and precise frequency response even at low-frequency range. The only issue I have ever had- and this may be a phone issue rather than a 5k one- is that sometimes the bluetooth is garbled when i start a playback session, requiring either a 5k reboot or a disconnect/ forget from the phone.Despite the simplicity of the form, the device has a very effective and functional design, more than striking or spectacular. Without using any EQ it is clear, very neutral and clean, presenting no hiss with the more picky sensitive IEMs I could try. Desire to learn and share knowledge of science required as is 20 years of participation in forums (not all true). Well, it was released in 2020 and it is supposed to be used mainly with smartphones so they expect that everyone should own an updated one. The highly optimized LDAC library and the ultra-low-power QCC512x enables the LDAC streaming more secure and more extended.

The FiiO BTR5 is the only other hybrid wired/wireless DAC/amp unit, as the other three are wired only. Bluetooth:​Generally pretty stable, though it is more stable over aptX than LDAC for me over longer distances. I know some people pointed out in some reviews that on the spec sheet, the BTR5 has some dedicated USB controller.The Qudelix 5K comes packed in an environmentally friendly cardboard box and includes a USB C to C and USB C to A cables of 120mm length each.
