Description of Issue
Two months ago, I began using Roon. Love it. I had great success using my 2017 MacBook Pro as a core. Songs started instantly, zero buffering, zero error messages. The laptop was connected to my network via wifi at about 250mbps down / 35mbps up.
I decided I was tired of leaving my laptop open and decided to pull the trigger on a dedicated server.
Today, I received a brand new Nucleus rev B (no ssd). I connected it to the network using CAT6 and connected it to my streamer/DAC (Hifi Rose RES150B) via USB 3.0 A to B. I updated the Nucleus software as directed by the pop-up in the Roon app. I switched from my MacBook core to the Nucleus core easily. Network speed at the Nucleus was tested at 960mbps. I use Qobuz and Tidal but listen to Qobuz primarily and expect to end my Tidal account.
Iām having a few troubles out of the gate:
Problem 1: About 1/4 of new track selections stutter at the beginning then skip to the next track. At the same time a message at the bottom pops up and says something to the effect of Qobuz is loading slowlyā¦ This never happened with the MB Pro.
Problem 2: When I send information from Nucleus to the RS150 via USB, I hear pronounced crackling in the higher frequencies during playback. Itās especially noticeable when horns are playing. When USB is bypassed and the Nucleus communicates with the RS150 on the network the crackling stops completely.
Problem 3: I use an iPhone 13 Pro with the latest software to control Roon. Now that Iām using the Nucleus, the iPhone gets very hot and burns through battery several times faster than when I used the MB Pro. The phone is about three months old and connects to the network via an Access Point thatās located about 15 feet away (Ubiquiti U6-LR). The battery went from 90% to 20% during two hours of Roon use.
Thanks, John
