The Halo integrated is a solid choice. You may find an open box or 'B' marked unit at Sight and Sound audio. Plenty of options, at 160 wpch at 8 ohms, it has a lot of power. I own the Halo C2, purchased used via ebay, great unit, really good build quality.
You can purchase the Magnepan LRS direct from Magnepan, 90 day trial, if you don't like them you pay return shipping and that is all. Option 2 trade them in during the first year for a higher priced pair of speakers. They will never fatigue your ears. Qualified down side, they need to be 4 feet from the back wall, to sound their best. You will need a subwoofer or better a DBA swarm bass system. Magnepans are also vampires, no sunlight on them. If you are near a dealer they offer the same trade up option. Or call Magnepan direct they may have some returned models to choose from.
I have called both of these companies, the employees know the equipment and can help with questions.
