Shouldn't source be maxed out and volume controlled via 5K amp gain?
That was a big ass letters recommendation on ES100.

In general that is the best approach. Remember that DVC often works by reducing the bit depth of the signal. It better to to send the full bits to the playback device and let it adjust gain at the amp.

„..Remember that DVC often works by reducing the bit depth of the signal..”
- can you explain this more ?

I can try. Full volume for a 16 bit recording uses all 16 bits. For each 6 dB of volume reduction from 100% you digitally remove 1 bit of depth (if done in software). Like many things in the audio world, it can be more complicated depending on specific hardware and implementation, so you may want to research for yourself.

Thank's, I'll check what's going on when I know what to look for

This might be a dumb question, but could I feed the 5K into something like the Schiit Sys or JDS Labs OL Switcher? I want to replace my desktop system and only use the 5k, but I would still like to have a volume knob.

Or would I be better off feeding the 5k into my element ii? But then I couldn’t sell my desktop system and get that money back.

Hey guys, I just want to clarify something, so I will ask.

I am using my Qudelix-5K with the TRI I3 and rarely with my 7Hz Timeless. What is the best practice/optimum streaming settings for Qobuz? Currently, I have it set on 24 bit Hi-Res/up to 192 kHz, for both Mobile Network and Wi-Fi, in the Qobuz App. In Qudelix, I have all the sample rates, selected. So, 44.1 kHz, 48, 88.2 and 96 kHz. Is this the best practice?

Remember that Bluetooth doesn't even have enough bandwidth for lossless CD quality, and everything is recoded and compressed for transmission. I see no point in using a source higher than 44.1/48 for Bluetooth because much of the information will be lost.

LDAC 990kbps can do up to 47khz lossless, anything above that (it can support up to 24/96) gets lossy compression.

Does anyone have an experience with the last build of the Qudelix 5K (updated proc), if there is some improvement with battery life ? I have one which is almost 2 years old and battery life is something like 4 to 6 hours with my moderately sensitive IEM (Sennheiser IE900) depending on what is activated as DSP/Power.
As I really enjoyed the battery lifetime of the iFi Go Blu (10 hours or even more), but some permanent little background hiss noticeable between tracks when I listen at a very low level volume, I couldn't keep it.
Basically the Sound Quality of my Qudelix 5K is a bit behind, but still rather enjoyable, I would say that just battery lifetime is annoying for my use .. I would like 10 hours or more at a decent power lever.
So what about the last Quedlix 5K Build ?

That's unusually short battery life. Did it use to be longer and degraded over time? Did you use the setting to restrict charging to 80% to preserve the battery?

No .. not really, as from beginning 80% was already a rather too short time for my daily use.

I listened with 3.5mm and got rid of the hiss. IIRC, most ifi products have some hiss listening through the 4.4mm output.

I ordered the 5K yesterday, should be here Friday. I’ll be able to comment on the quality then.

Looking forward to your thoughts

I finally pulled the trigger on the 5K - arriving March 1st.

Couple of questions for the experts out there...

Question 1: If you use an AutoEQ setting, are you able to use the Graphic equaliser to fine tune it or does the PEQ allow you to do something similar?
Question 2: Has anybody tried the Sennheiser HD700 (150ohm, 105db) with it? If so, do they perform ok on 3.5mm or do I have to go 2.5mm?
