The main “issue” I have with Audirvana when playing on a PC, compared to my streamers, is the bass. The low-end notes feel light. Especially at lower listening levels (45–55 dB), my streamers render articulate, clear bass, whereas Audirvana on PC sounds softer, lacking texture and weight.
I make sure my PC is running on battery, connected via Ethernet, with Wi-Fi turned off, and all other applications closed except Audirvana. When checking Task Manager, I noticed Audirvana uses over 800 MB of memory (for comparison, Google Chrome uses over 1,100 MB), placing it near the top of the list. This suggests it is performing a fair amount of background processing or optimization. It’s no surprise there’s still no full implementation on mobile devices, as it would likely be quite memory-intensive.
I also tried inserting a DDC between the PC and DAC, using fairly decent USB and I²S cables, but that did not improve the bass performance. It still seems somewhat attenuated, almost as if a high-pass filter is applied. I believe I was running in WASAPI Exclusive or ASIO mode, which should be bit-perfect.
In any case, if you have suggestions on how to restore the bass performance, I’d appreciate it.
