With the RME SRC set to 96kHz: Cleaned up but still poor.Ĭompared to the AVR through the TV, optical to RME, with SRC (same without pretty much): Much nicer! Also, the S50 also appears to resample everything to 44.1kHz, the RME status reports. USB file, dig out to RME dig in, then analog loopback, with no resampling: can barely lock to it. Much cleaner and less jitter though than the S50 PRO. Doesn't like the 9kohm load of the RME much either as results worse than Amir's (i've been through this in another thread). THD is the preouts saturating (see Amir's review of the V6A). 1dBFS 48KHz, 24 bit USB FLAC FILE IN, ANALOG OUT (2VRMS measured at S50 for 0dBFS, rme set to 13dBu full scale so you expect -5.8dB for -1dBFS in): Not great.įor comparison, the AVR (Yamaha RX-A2A=RX-V6A pretty much) analog out for the same test was: Wifi or a USB file also made no difference. Specs only say THD is 0.03% which is indicative perhaps of things to come, but SNR noise 110dB odd.įor a -1dBFS tone via any WAV, FLAC or MP3 I got the same results. I was going to test the ADC as well but given the performance here there seems little point. A sample rate converter or two helps to clean it up a bit but it is still worse than the AVR (Yamaha RX-A2A=RX-V6A).

TLDR: it's not great, with poor THD and worse jitter.

Both seem to retail for US$200.Īs no direct digital in, testing was limited to recorded REW tones etc played back via wifi (via Foobar2000 UPNP), usb stick and also bluetooth.Īnalog or digital, depending on the test went to an RME ADI-2 PRO analog in or SPDIF in->main out->analog in loopback. The S50 PRO is the just superceded Arylic streamer, with two analog inputs. I need to use digital out generally as it goes into my DPA-1 digital preamp to use the RoomPerfect room correction, then to RME ADI-2 final DAC. I bought one of these recently, hoping to simplify my Spotify Direct use as I was previously using my AVR and optical out of the TV extracted from HDMI, into my DPA-1 digital preamp.
