Nucleus+/1.6 build 416/stable (64 bit)
I bought the Nucleus+ a couple of weeks back from a UK based dealer.
Here’s a log I’ve kept because of playback issues covering the past week or so:
Issues with playing through Benchmark usb with Nucleus
Left Nucleus playing to Benchmark usb overnight Aug 9th. Showed flashing light in the morning. Roon recognised usb, but attempts to play just showed the selection failing to play. Turned Benchmark off with remote. Turned back on again but no connection made to usb. Turned off again with remote. Disconnected cable both ends, reconnected, powered on again and system worked.
Switched Nucleus to internet radio. Added a radio station - RTE 1 and played it successfully. Tried switching to Lyric FM and connection was dropped. Disconnected from Benchmark, reconnected, steady blue light but no playing and light flashing blue again. Disconnected from Nucleus, reconnected, steady light but lost Nucleus on the remote. No sign of Nucleus on the network.
Disconnected Nucleus from all connections. Reconnected and it functioned again.
Problems only appear with usb to Benchmark. Chromecast audio Benchmark works fine.
Turned on the Benchmark kit. usb light was steady. Started Lyric FM on Nucleus - no issue. 15 minutes later switched to Qobuz playlist ‘Stormy Weather’. Played first track ‘Riders on the Storm’ and when finished dropped the connection. Switched DAC to Chromecast Audio and played without problem.
Switched DAC to usb, flashing light. Turned DAC off via remote, disconnected both ends of usb cable, reconnected, steady blue light. Played internal storage playlist from Nucleus to DAC.
90 minutes later stopped playback and selected internet radio BBC 4, working fine. Then tried switching (without first stopping) to Radio Paradise - dropped usb connection. Switched DAC to Chromecast/Optical and Nucleus played radio no problem. Disconnected usb cable from DAC and Nucleus, music stopped playing. Reconnected usb cable, switched DAC to usb, steady light. Selected usb on Nucleus, played radio fine.
Back home, started playing Nucleus via usb about 5pm. All well until sampling different tracks via Qobuz. Was playing fine until switching mid track to another Qobuz artist when the connection dropped. Nucleus appeared to keep playing but no output from DAC - just the flashing light. Switched to Chromecast via DAC optical - played fine.
Powered on Benchmark DAC and switched to usb - blue light still flashing. Disconnected at the DAC end and reconnected - steady blue light but Nucleus couldn’t see the usb connection. Disconnected at the Nucleus end, reconnected and got steady blue light and Nucleus could see the Benchmark usb. Nucleus could see and play to Chromecast through DAC optical connection throughout.
Switched on DAC from remote and switched it to Chromecast/Spotify. Shortly after switched back to usb, light still steady and played internet radio. Switched to another radio station and usb dropped out. Nucleus showed playing continuing but no music played through DAC, blue light flashing. Switched DAC to Chromecast and played with no problem. Benchmark usb still showing as a zone in the Nucleus zone list. Switch DAC to usb and choose usb zone in Nucleus and play radio station. Nucleus shows playing activity to usb zone but DAC blue light flashing. Disconnected/reconnected usb at Nucleus, steady blue light. Lost connection to Nucleus core. Switched DAC off with remote and back on. Steady blue usb light on DAC. Still no Nucleus Core. Disconnected power cord from Nucleus, reconnected, still no Nucleus Core. No sign of Nucleus on IP scan. Disconnected Cat6 connection at Nucleus, reconnected and Nucleus shows up on IP scan and iPad sees Nucleus Core. Select radio station on Benchmark usb and blue light starts flashing. Switch DAC to Chromecast, same for Nucleus, plays perfectly. Meanwhile, Nucleus shows music still playing on Benchmark usb zone. Disconnect usb from DAC, reconnect, steady blue light. Nucleus still lists usb zone but music stopped. Hit play button and radio station plays immediately.
Came back some hours later and started sampling Qobuz tracks through usb connection. Played ok for a short while but eventually lost connection whilst forwarding through a Stones album on Qobuz. Nucleus shows music playing on Benchmark usb. Switched to Chromecast on DAC. Stopped playing, turned off DAC with remote.
Turned DAC back on and switched to usb, blue light flashing. Disconnected usb at DAC, reconnected, steady blue light. Selected album on Roon Core, pressed play, usb disconnected. Core shows Benchmark usb and music playing, but no signal received by DAC. Turn off power switch on Nucleus, lose Core on iPad. Turn power back on, usb on DAC shows steady blue light. Short time later Core reconnects on iPad. Hit play button on Nucleus, usb disconnects on DAC, flashing blue light. Do a four second switch off on Nucleus. Switch Nucleus back on, steady blue light on DAC. Core reconnects, press play, and it does!
August 17th, Saturday morning, system left on overnight, usb blue light is flashing. Tried playing from Core but no go. Core shows track after track trying but no go. Turn DAC off with remote. Turn DAC back on, blue light flashing. Do four second power down on Nucleus. Power on Nucleus, steady blue light on DAC. IPad reconnects slowly to Core and then music plays ok.
Turn off DAC with remote, leave for two hours. Power up DAC, steady blue light. Play album from Core, usb disconnects, flashing blue light. Do four second power down on Nucleus, power back on, slow re-connect iPad to Core, music plays fine.
Here’s Benchmark response received earlier today:
Engineering read through this and are saying it’s either a problem with the Nucleus or with the DAC. We run our Nucleus with Roon Rock and have not issues.
A thought is is that the Nucleus USB may not be functioning properly. Possibly it’s not providing the steady USB power which our DAC requires. It might be “flaky”. You could try a powered hub between Nucleus and DAC. It if works fine, then that was the issue, but the Nucleus needs repair as it should provide the proper power on the USB.
If you try the DAC now, on a different computer, will it run without issue. If not, then it has the problem.
Let us know.

Will try testing tomorrow but interested in your views meantime.
