1. The speaker terminals on the back of the amp are very difficult to get to, as they are close together and somewhat recessed. I don't think that spades would work. Bananas or bare wire are your best bet.
2. The ground lug for the turntable is on the underside of the unit, and it's a fair distance from the RCA jack for the phono input. If you have a phono cable with an captive ground wire, you may end up with a fair amount of tension on the phono cable/ground wire.
3. The power cord jack is right next to the speaker binding posts. My power cable (an Anti-Cable level 3) sits snugly against the binding posts. If my power cable's connector were any larger, I wouldn't be able to use it.
I guess these are the compromises that have to made to provide a small footprint amp like the Brio. Will follow up with listening impressions later.
