I call myself The Occasional Audiophile because I only occasionally perfectly triangulate myself seated in front of my toed-in speakers listening to the music critically ... I mostly listen to music in the background while doing other things, it's a small house filled with wonderful music. I listen to CDs played on a 1999 Technics SL-PD8 5 disc rotary changer connected to a 2024 Schiit MODI+ DAC via toslink optical cable.
I upgraded my system (12/8/2025) when I traded away a set of ADS L780/2 speakers for a 1978 harman/kardon 730 twin powered receiver. The 730's high current dual mono design allows each channel to deliver its full RMS power output to my large ADS bookshelf speakers without compromise, the model L980/2 loudspeakers were made in 1983...refinement with Max Headroom. These ADS loudspeakers compare favorably with high dollar . I've also added Grado RS2e headphones that were made in 2014.
