Me too. Right now I have MartinLogan Vantages, MartinLogan Stage, and MartinLogan Vistas all hooked up to it and it drives this cruel load with no problems whatsoever. Mind you the Vantages and Vistas can dip below 1 Ohm.
There is a reason HCA-2205's sell on Audiogon just about as soon as they are listed. They truly offer 95% or more of the performance of the 4500 Dollar A51 for around 1000-1200 Dollars used.
Compared to the very popular Emotiva XPA-5, the 2205 has almost twice as large of a Toroidal Transformer (2.0 versus 1.2 kVA) and almost triple the amount of Capacitance (150,000uf versus 60,000)
Granted the 2205a retailed for 2500 Dollars new as opposed to 799, but used the prices are quite close and my Parasound has been on 24/7 for 10 years as well.
