Part3
The pa1 is a USB interface for mobile devices, designed to filter and reduce noise for USB signals and USB power supply. However, I was initially disappointed because the pa1 could not power on the digital source hiby digital m300. Although my phone could power on the pa1, it sounded more muffled than directly from the m300, so I set the pa1 aside.
It was not until L&P released the wy1 that, luckly , the pa1 was given new life on the m300.
After getting the wy1, I eagerly connected it to the hiby m300 and a power bank. With the support of independent power supply, the sound of the w4 became more dynamic, greatly extending both tre and bass and further enhancing what I thought was already a large soundstage. I also noticed that the wy1 itself is a very neutral, high-resolution sound. superior to qls and dd in quality, but lacking the natural smoothness of the wp2.
The significant improvement of the w4 with enhancements in dynamics, density, soundstage, and bass, truly indulging my ears. Of course, I still miss the natural and smooth sound of the wp2.
How to combine the grand, dynamic sound of the wy1 with the natural tone of the wp2, I thought of the soundaware pa1. I decide to tryout the pa1. I plugged the
Pa1 into the wy1, then connected the other end to the wp2, and anxiously connected the power bank:it just works!
At that moment, I realized that the so-called incompatibility of the pa1 with the m300 might be because the otg USB port of the m300 couldn't drive the pa1.
When the wy1+pa1+wp2+w4 are combined, the sound of this setup is incredible, instruments and vocalist surrounded me seems like true to life. It changes the stereotype of me on dongle sound.
Currently, I am extremely satisfied with this setup.
