All hardware (except speakers and headphones) is placed on a wall-mounted sideboard tailor-made of steel and solid walnut. The speakers are placed left and right of the sideboard with no tilt 2.25 meters from each other and 0.30 meters from the wall.
I have started to build this system a year ago with the cd player, the amps and the speakers and have added the turntable this year. Most recently I have added Grado RS-1 headphones driven by the Grado RA-1 amp which I link directly with the source using Jcaudio WOW interconnects.
I do not intend to upgrade my system ever six months. I just want to have a system which produces great sound. However, if I feel that I should add or upgrade a component I will consider it. On thought is to add another Cambridge Audio A-500 power amplifier and bi-amp the speakers.
System edited: I use YBA HP Glass speaker cables and Audiovinyl interconnects (Suhner+HUber cables and Neutric connectors). When I use my headphones I link the Grado RA-1 directly with the source using Jcaudio WOW interconnects.
