I see no reason to delete your post, it is not offensive and contains a simple test that anyone can do on their own with the necessary tools and a little skill and patience. The fact that this thread doesn't have 100 pages yet, but only 13 says a lot about the situation. If the phone had...

And this explains the strange silence on this thread... in practice the phone does not eliminate android's audio resampling (as communicated by the company and by some reckless reviewers), it is not compatible with UAPP (it does not detect the internal DAC) and It has a poor implementation on...

Q15+Cayin iHA-6+HD6XX (Custom Can Mod) Great synergy!!!

The strange thing is that the same powerbank, when connected with the Aceele hub works perfectly with all the dongles I own... the problems arise when I connect it with Y cables (L&P WY1/CB19). However, this only happens with three dongles of all the ones I have (RU7/M15/W4) while it works well...

Has anyone tried using the W4 with the Luxury&Precision WY1 cable? When I connect it to the powerbank the W4 restarts continuously, while if I connect it to the same powerbank via the Aceele hub this does not happen. Do you have any idea what it could be? Thank you.

If you're looking for a single, complete machine, the H7 is definitely superior... but the Q15 with the PA10 is superior. In terms of tonality, detail rendering and general quality they are similar, but the amplification of the H7 is superior, so in the end the sound of the H7 is richer and more...

In my opinion, no portable amplifier can bring out the best from the HEK Stealth and it's not just a question of power, but everyone can drive them. I tested them with the H7 (1300 mw), with the AK PA10 (1890 mw), with the iBasso DX220MAX (1900 mw), with the Venture Electronics RA2BFE (3000 mw)...

It improves it in almost every aspect... quality and quantity of details, soundstage, fullness of notes and their depth, general richness of the sound, everything becomes more vivid, colorful, dynamic, but at the same time soft, much less edgy, but clear, limpid, the sound becomes deep...

Simple... because on its own it's a 350 euro amp/dac that sounds like a 700/800 euro dap, while with the AK PA10 it's a system that costs less than 1k euros and sounds like a 3k/4k euro DAP.

A very high level system for your IER-Z1R (FiiO Q15 + Astell&Kern AK PA10)

For those who own and love the Q15 I advise you to think about purchasing an AK PA10... together they reach incredible heights!!! Using the excellent line out of the Q15 to equip it with the enhanced amplification of the Astell&Kern SP3000 (Class A - Teraton Alpha) is a very wise thing to do. ;)

Some considerations on the use of the Q15 alone... it is certainly an excellent device with a sound that is enough and more than enough to make 90% of users happy and considering its price it can certainly be defined as a bargain without any doubt. Having said this, a direct comparison with the...

I noticed that the Q15 has the volume that increases exponentially and not linearly like the H7... in fact at the beginning it seemed much less powerful... Let's say that where the H7 makes the SLIIVO SL-T6s sound with 27- 30 volume at Q15 requires 47-50 (desktop mode).

A little warm up and I'll let you know as soon as possible...

The Q15 has finally arrived, but with sub-zero battery... now a good charge and let's start with the tests...
