If the Peachtree Nova 300 has any appeal, then have a look at the Nova 150. You may not need the extra watts of the 300 and AFAIK the features are otherwise about the same. The DAC chips may be different.
Keep in mind, though, that the Nova series amps have no onboard streaming capabilities. Peachtree has been pushing the Bluesound Node 2i for that. On the other hand, one nice feature of the Novas is their support for feeding an iOS device into the USB-A port. An iPhone/iPad/iTouch then could be used as a Roon endpoint as well as a direct source.
