I think it is the perfect match for my Head-Fi system.Īs mentioned above, the comparison is based on headphones sessions only. On the other hand, it is surprisingly natural and musical, and good for prolonged listening sessions. It carries enough details, but not as much as the nowadays delta-sigma DAC. Teradak TDA1387: The bass is slightly less weighted when compared to the other two DAC HATs. Sounds from R93 is balanced, with good details but not much harsh. Ustars R93 AK4493: My favorable digital filter setup is Short Delay Slow Roll-off. Hifiberry Dac+ Pro: It sounds balanced and crisped, but I think it has the “digital sound” of some old day CD players, and can get fatigue easily. As for Head-Fi system, I have focused on tonal and sonic balance rather than sound stage, etc. The RPi was running mpd + mympd of Dietpi v6.32.2, with music files from NAS (via samba mount). The RPi unit was powered by BRZHiFi 5V LPS (which carries both USB and 5.5/2.1 DC sockets). I have used RPi 3 for testing the three DAC HATs. It is a very well known DAC HAT, and should serve as a good benchmark baseline. Same on both Cronos/Rhea boards.Besides of the two new DAC HATs, I also have a spare Hifiberry Dac+ Pro lying around. And if I change Cronus Input from 5.0 to 5.3, still 3.3V.īut as soon I connect a Rhea board, regulator seems to stop working and I get 4.1V.ĭunno what the problem can be. Then I discovered if I remove both Rhea boards, regulator seems OK. I see that Cronos use 150mA, but still 4.1V at pin to Hermes "3.3V Input". I then gave up and assembled my second Cronos board and Rhea Board. I checked every solderjoint again on the Cronus, found nothing. If I lower the voltage from 5V to 4V on Cronus Input, the pin with 4.1V going to Hermes board also gets lower voltage, so something wrong with regulator I thought. I then disconnect Hermes and only measure the Cronos board. I started measure at the Hermes board, and then saw that I have 4.1V at Hermes "3.3V Input" from the Cronus Board. I have continued with the troubleshooting. If same problem with the extra Cronos board, I skip send that back, and pay for that board too. Should I try solder components on the extra Cronus board, and if it works then I send the faulty one back to you so you can inspect. The plan is to send my extra Cronos Board (and extra Buffalo board) back to you. Player starts playing track OK, but no lock on DAC.Ĭan it be some problem with the Cronos board? As I have tried change the Rhea Pair with no success.īut dunno what else to try. I verify that I have 5V (4.99V) at input on Cronos board. Replaced my three U.FL Connection wires with new ones. Inspect every solder joints on the Cronus/Hermes Board, and solder at all through-hole pads again. I have now reflashed Amanero and tried it direct to Buffalo board. Will verify with a laptop and short usb cable tomorrow and see what happens.Īny more suggestions? If nothing work is it worth trying the Cronos board I was planing to send back? But then I have to solder on it and buy that too. But when pressing play, nothing happend/player unresponsive. I now tried play direct from my computer with a long (10m usb cable) that I used to flash amanero card with. Hqplayer find Amanero as usual and start playing track when pressing play, but no lock on DAC. I use a streamer (microrendu) at Amanero input. But then same result, no light on "LOCK LED". Then after a while I started the one suppling DAC. Main switch then start Amanero/Cronos + AVCC supplices. I now tried a on/off switch for DAC power supply. ![]() I have one powersupply for Amanero/Cronos, one for DAC, and one for each AVCC. Anyway, tried another set of Rhea Pair from that. I have two sets of cronos (lost DAC package arrived, will send one back, talked to Brian about that). I have measured that Cronos/Amanero board take 200mA from my 5V powersupply (can handle 350mA). I have checked R1-R7 mounted on the Cronos board, and I measure 30 ohm where D1, D2 and DCK end up at Buffalo board. Question, should Prescaler at Amanero be MCLK/1 as in picture in diyaudio link or MCLK/2 if have two clocks on Cronos? I have it like in the Picture MCLK/1. Amanero found by HqPlayer and track plays, but lock LED not light up. I have now also reset and update Amanero with Slave_For_1080 and config bits as in I have them stacked on top of each other and D1, D2 and DCK with U.FL wires to Buffalo board. So problem seems to be Cronos/Amanero board. I have problem with Amanero-Hermes-Cronus-Buffalo-IIIsePro38, no signal lock.Ĭhanged SW1 P1 to ON, and tried the spdif input with a dvd player.
