Which headphones render a more transparent sound between the M1570 and the AKG K702?

My Rock It Sounds R-50 that I got 9 years ago still amaze me with clarity, tonality, vocals, instruments, soundstage, middle and high frequencies. They sound great with tracks where drums or bass slam are not a prominent part of the presentation. Forget about these with EDM tracks. But, with...

What is the op-amp that has given you the sweetest tone that isn't too big to keep your NX3S inside its enclosure/shell?

Tonality is a distinctive trait of sound quality. When you give it a distinctive score apart from the bass, mids, treble, soundstage, separation and other sound traits, you are making a clear statement about how appealing the tone is to your ears. It is hard to find someone who officially...

Hola Marcus. Thank you for your reviews. One of the things that was very helpful from your reviews content was the score (from 0 to 10) on tonality. For example, I got the FiiO BTR3 knowing that it was going to sound good to my ears because you gave it a score of 8.9 in tonality. Tonality is a...

I solved the issue. Thank you for asking for an update on this issue!

Here is the official FiiO BTR5 thread: https://www.head-fi.org/threads/fiio-btr5-dac-es9218px2-csr8675-bluetooth-5-0-usb-dac-supporting-up-to-384khz-dsd256-native-3-5mm-2-5mm-aac-sbc-aptx-aptx-ll-aptx-hd-ldac.918298/

I just got a HiBy W3. It won't pair with 3 cell phones running on 3 different Android versions. In one of them the cell phone responds with "Wrong PIN or passkey. Try again?". I have already deleted/reset the stored data and the cache for the system Bluetooth application, to no avail.

Your next step toward upgrading your setup should be getting a USB Bluetooth transmitter. The sound quality of aptx HD that you are gonna get, will be at the same level of your BTR3 wired connection.

The needed speed for data transmission (the 1s and 0s stuff) between your source and the BTR3 will be covered by USB 2.0. So, the higher speed of USB 3.0 doesn't make a difference in this application. That is the theory (and obviously all or most of the reality) in this case. You can use USB...

Don't rest assured that there will be no difference in sound with different types of USB ports. There have been differences in sound quality when switching a part of my sound chain where technically the sound was supposed to be exactly the same. For example, with the same BT codec my BTR3 has a...

Which receiver has deeper bass to your ears between the W3 and the UP2? Which receiver has better mids to your ears between the W3 and the UP2? Which receiver has better highs to your ears between the W3 and the UP2?

"just double amping it then?" To my ears the amplification power of the BTR3 is a joke for headphones and it isn't much for IEMs. This and the BTR3's small size make it an ideal receiver to be connected to an amplifier. Obviously, with an amplifier the BTR3's portability goes down the drain...

Yes
