![]() Slightly curious 2 of the DSP options as to what they do and whether the amp allows me to set them, last one seems self explanatory though. ģ2bit processing up to 192khz (have only need to upsample low quality files through JRiver when using ASIO)ĭigital Filter: fast/slow roll-off frequency (this is an option within the amp, fast just speeds playback affecting speech intelligibility so i have it on slow),ĭSP: De-emphasis for 32kHz, 44.1kHz, and 48kHz sampling,ĭSP: Click-free soft mute and volume control. I have not checked if it does any other funny stuff when receiving the signal from the source but will try to found out. I'm using an Pioneer SC-LX87 amp which has ESS SABER32bit Ultra DAC's in it. I'm not that knowledgeable about the internal operations of DAC's but i thought using an ASIO connection through a USB interface it sets the DAC to the correct timing without upsampling if it can support the various playback rates? I do not know what all this means or what may be significant but all these observations are with the same NAS connection described above. Changing from direct to play from memory changes the network activity pattern but not the peak values. Then I checked the box to open the device with exclusive access. Also, checking 'play file from memory' made things sound congested. In case 1b (interrupted playback), the average is the same but the peaks are in the 50-60mb/s range. The sound was more extended, faster, and lighter on its feet with the smallest buffer sizes. In case 1b (good playback), network usage averages 2% but peaks in the 85-100mb/s range. On the other hand, network behavior varies strangely. However, when I look at the individual cores, only 4 are running and 0 and 7 have most of the load. In all cases, the CPU/memory usage seems similar (5-22%, mostly in the teens, and memory usage at 2-4 GB). Converted to 176/32 or 88/32, everything plays. Converted to 192/32 or 96/32, there are interruptions and bufferings every 30 seconds or so. ![]() With a DSD256 5 channel file converted to PCM and DiracLive, the success depends on the target resolution.Ī. I relocated the NAS to the same switch shared by the MC server and it worked immediately.ġ.
