After a bit of forced spousal persuasion, my amp and cab are now tucked away out of sight in their respective cover/case, only to come out for gigs. The problem, then, is practicing. I've managed for ages unplugged, but decided to try and use some of the other devices lying around the house.
First I tried the [url="http://www.harmankardon.com/EN-US/Products/Pages/ProductDetails.aspx?PID=SOUNDSTICKS3AM"]Harmon Kardon Soundsticks[/url] but the buzz was bad, and the tone a bit boomy.
The real surprise came when I tried playing through the [url="http://www.pure.com/products/product.asp?Product=VL-61212&Category="]Pure Oasis[/url] digital radio. Quiet, but loud enough to play at home, and a lovely, full, true representation of my bass' tone. And a bonus is that I can take it anywhere. Maybe I'll take up busking again
