The VAC or CAT will handle the Avalons with ease. The Atmasphere MA1/MA2 would be another product line I would give much effort to audition. I think it ultimately comes down to balancing with your source and preamp sonic strengths/weaknesses.
I own the VAC Phi 300 and took it over to a friends house that has Lamm 1.2 driving Kharma 3.2's. The Vac 300 was the clear winner. He will be makeing the switch to the VAC soon.
