After I posted my previous comments last night, I lay in bed reflecting on the sudden improvement in the sound quality of streaming that I am experiencing.
A bizarre and heretical thought hit me like an express train. Yesterday, thanks to my kind wife, I had replaced the ageing iPad and Kindle Fire that I have been using as a Roon Control Point with a new 13 inch iPad Air with 512GB. Overkill for the job perhaps but likely to be useful for other purposes. This was an instant upgrade from an ergonomic point of view. The screen is bigger, the connection to Core and Linn DSM more stable and the screen refreshes much more quickly. Could the new iPad have also been responsible for the improvement in sound quality?
Google Gemini thinks that may well have been the case. The insecure connections of the old iPad and the Kindle would have been generating extra traffic over the wifi, which may well have been causing noise and thus be perceived as digital glare affecting the sound. Whether this is true or not, I’m going to take the win and enjoy the improved sound quality.
One thing is clear, my long term dissatisfaction with streaming is over.
