Yes, the ceramic Avalons can disappear and image really well. But, tonally, they are thin through the mids right on up to the highs. I am involved with many, many concerts listening directly to unmiked horns, drums, piano, strings. Sorry, they don't sound that thin in real life.
This is the type of speaker I call an "audiophile speaker", and they do those audiophile checklist things: image, disappear, depth, detail, image, detail, bass, detail, top end extension, detail........but the sound of real instruments take a bit of a back seat, yielding a lot of detail, which making a speaker a bit thin-sounding enhances.
Float things in space, give lots of detail, that floats audiophiles' boats. Did I mention the detail?
