Since I have retired I have ditched the speakers and gone whole into headphones primarily because my dear friend and neighbour next door to me contracted Motor Neurone disease and I wanted to make the time he had left to him as peaceful as I possibly could. After he passed I just didn’t want to go back to the whole speakers thing so I built up my headphone system to a superb sounding one. I have a bespoke audio computer that I built myself and my files from ssd drives and streams from Qobuz and Idagio are either streamed straight through to my PS Audio DAC and into my Luxman headphone amp or I record them onto a hard drive on the computer clean them up and then store them onto a SSD in .dsf form and I play them through my J Play player because both Qobuz and Idagio drop files from their sites without any notice. At least this way I still have the files to play.
My tweaks nowadays centre on RFI and EMF distortion suppression and the ubiquitous Fuse replacements and they all seem to be very successful according to my listening tests. I probably have lots more to keep me going into the future. Watch this space !!
