You should also try tweaking your software player. Try Playpcmwin.

Did you try tweaking the cable to match your system. Phasure Lush and Ifi Gemini are the only two cables I know that are configurable to different systems.

What does tin plating do for power? Silver playing for data makes sense since with high frequencies, skin effect pushes the charges to the edges of the conductor. What’s the special electrical property of tin? Does it do well with large input currents? Or is it merely cost saving?

I was surprised how awesome hd800 sound out of apogee groove (I prefer the groove over quite a few desktop amps for the hd800. It handles headphones not requiring lot of current very well). Maybe you could give it a consideration too. Or if you’re looking for something modern, maybe the questyle...

Looking forward to your new product. Hopefully it can be more powerful if it’s battery powered as it would no longer rely on usb power supply.

Many portable devices exist (I am looking at ifi as an option due to Mqa support and their custom filter) but I would be more inclined to questyle because the design/filter choices are better aligned with my preferences (except for being not battery powered)

Would questyle be interested to make a battery powered m15 with maybe more output power?

You mean like ifi idsd Diablo? Or bakoon hpa01? The Diablo can do NOS

Is cayin ru6 something that might interest you? Also, the choice of digital filter can change the output noticeably. On akm dacs I like the super slow filters, if you have dacs that allow filter swapping you can try changing those.

If you’re interested in Bluetooth, Logitech x50 and x100 are very good. (Also have a coax in). I actually found expensive Bluetooth speakers to sound bad (just sound loud and use quite aggressive dsp). Apparently Sony also has a decent budget portable speaker but forgot the name (sbs or...

Wtfplay is great! Xxhighend is even better (I love the custom upsampler). Yet to try pure asio player. Is it available for free?

It can even be about measurement settings inconsistencies. Headphone is not the same as a resistor and real world systems are not linear time invariant.

Glad you found a budget option that worked well for you! I bought two usb cables that together costed close to half the price of my dac (dac is a budget one 😅).

The numbers don't show anything audibly concerning to be honest. And resistors are not a 1:1 replacement of headphone for analysis purposes. Resistors have no mechanical load or movement, while a headphone does. While I am yet to buy a questyle m15, I do have an apogee groove, which uses current...

Thank you. Looks cool!

Looks cool. What is the amplifier that you’re using, and what’s the other device that goes along with it?

If you are fine with the spacing restrictions, uptone uspcb is awesome! It’s not really a cable but rather a pcb connecting from pc to dac. If you’re going expensive it would be preferable to find one with tweakable connectors and properties like phasure lush 3 or ifi Gemini. The overall...

The earlier cable might have not had enough shielding I guess. Might be possible to probe and check too.

Groove does work with phones but the output will be limited by the transient current supply capability of the phone, and hence generally sounds more controlled on a PC with respect to power. Anyway, my main target is full size headphones so more clean power is what I desire first and foremost...

Any idea how the m15 compares to Apogee groove, especially for driving headphones requiring significant current (my srh1540 requires quite a lot of current for full potential). I like the amplifier topology, the analog section implementation of the apogee groove but am not very fond of the sinc...

Why is it limited to renderer instead of full decoder? Power consumption and space limits (for the usb transceiver and processor)? I am interested in the m15 (to replace my current transportables), but I wish for a slightly more powerful, battery powered unit, preferably with full mqa decoder...

Where did you get the red case from?

I don’t think any of the PC audio deniers here have tried any customisation on how their OS handles the components and audio path. With a low profile distro like wtfplay (basically almost shuts down all components other than ones necessary to just keep the system running and feed usb out, and...

If you have the chance, play around with the interpolation profiles (also called over-sampler settings in some cases). I really like the super slow profile (marketed as the more natural/life like profile by AKM) on AKM DACs, especially with music sampled at 88khz or higher (truly sampled at...
