Hi
Thank you again for being so tolerant! I am not sure what dual aes is or what costs it involves, probably cabling of some sort? It seems to have settled down, probably as i have not been playing any sacds anD the switching seems yo be where the problem manifests. Am in Farnham in surrey, one of the cables is a old firewire ( pale grey…old dcs issue) as upsampler/clock only came with one firwire whereas the cable routing for a 4 box needs 2 . Luckily i had the old one to hand, probably dates from my first elgar so it could be just old. I am not sure if these cables are the sort you can ge5 on amazon for about £5, if so then its worth a punt. If however one needs hydrogen nuclear infused cryogenic wire then it no doubt will cost a fortune!
The upsampler is showing 24/176.4 to dsd, however when you power it down whilst playing a cd the sound carrys on as normal…implying that is not offering any sonic gain?
The manuals are not very clear in this regard and assume you have a computer based knowledge, i dont…i just like listening to music!
