At the risk of thread drift, ASR hasn't resulted in a purchase, but Frank's posts on turntables has resulted in me restoring the LF filtering on my turntables' phono stages. These are essential for broadcast use as any excess LF will just soak up transmitter modulation for no good reason, but I thought that at home it wasn't necessary so I bypassed the filters.
Having read Frank's posts, it got me thinking about what else excessive LF does, not just with headroom, as I'm not short of that, but for LF distortion in particular. This afternoon the bypasses came off.
