Levchappy,
I know what you mean. It really sucks when experimenting with an upgrade means getting rid of an existing piece of equipment.
On another note, and not to get off on another rant about this vs. that, but I took a look at the specs on the Sherbourn amp that you are interested in.
Assuming that the manufacturer's published specs are on the optimistic side, the specs do not instill much confidence with regard to the amp's abilities. Most notable to me are the power ratings at 8 and 4 ohms. The 4 ohm rating is less than 50% more than it is at 8 ohms and they clearly state that the minimum recommended load impedance is 4 ohms.
Again, I don't know how this amp is going to handle your speakers with the 4 ohm nominal impedance, with it dropping down near 2 ohms a lot of the time.
Honestly, and again, just based on the published specs, I think I'd consider keeping the Levinson and getting into an Emotiva 5 channel amp. That way you can keep the Levinson for two channel and back that up with the other 5 channel amp for home theatre.
I'm only saying this as a personal thing, because I've never been wild about Acurus amps. They aren't for everyone.
