I need speakers for low volume listening -

BrianV - if you love the Angelus, you will certainly like the TC50. Not as extended on top or bottom, but richer mid-upper bass, compared to the ANgelus. I have found them to sound good with everything from a Harmon Kardon to Pass Labs Aleph3 to JJ828. They will reveal the differences between electronics, but never seem to sound bad with anything.

Unfortunately the TC50s are to big for my application. I have had them and loved them. They were wonderful even for 2.1 movies.

dont know the rest of your set-up but when I added a quality preamp, lower volume listening was improved 100%.

If you need a small speaker and like the Spica sound, I would recommend the Audio Physic Steps from the late 80s, before Joachim sold the company. They offer a much more detailed sound than the Spicas, but are still very natural sounding. They have a much smaller footprint than the Spicas, but I don't know how they do close to a wall. Probably best far from side walls, though.

If the TC 50s are too large, I to will suggest a good set of headphones (with good headphone amp).
