before I upgrade to 1.5 firmware, i would like if those who did the upgrade noticed any new problem or sonic signature change ? thanks...
The 1.5 firmware is excellent!
FW 1.2 had been my benchmark for the N30’s sound quality, as I had limited time with FW 1.0, which was even better.
Here’s my comparison of 1.5 with FW 1.2 so far:
• Soundstage: 1.5 offers a slightly wider soundstage on the X and Y axes. I can’t comment on the Z axis due to my IEM’s limited depth rendering capability.
• Imaging: 1.5 has superior imaging, with instruments better spread out on the stage. Vocals are more centered and intimate, reminiscent of FW 1.0.
• Dynamics and Clarity: Both are excellent in FW 1.5, matching the quality of 1.2 and improving significantly over the messy performance of 1.3 and 1.4.
I’ll need to see how 1.5 performs over a few days, as some users reported sound degradation with FW 1.3 after a few days, possibly due to a buffer overflow or similar issue.
Testing was done with PW FTS + RN6 in P-Mode, Class A, High Gain, Moder Timbre Tube Mode. I find this modes combo sounds the best with RN6.
Another improvement in 1.5 is the charging display when the device is turned off. The new display is larger and easier to read. However, the charging limits are not respected when charging the device in the off state.
Cheers!
