Oops, I missed the fact that the Lepai was an integrated amp

.
The
Dayton APA150 is integrated, has a nice compact form (5½" H × 6" W x 11½" D), a nice price, but it is rated at 75 wpc at
4 ohms. They don't rate it at 8 ohms with two channels driven, but we can assume it will be less. For what it's worth, the Parasound zamp was 45 wpc at 8 ohms, and 60 wpc at 4 ohms. So, the Dayton is a possibility. Nice catch
It always works better if you read all the web page
