Hey aseaman, I just sold the .05, and now have the 1.0 hooked up to my amp only, as I just purchased a Synergistic Research power cell for the rest of my system. That 0.5 is what got me going on the power upgrade and let me hear what it can do. I just love the sound that my system puts out now. Very detailed,clear and alive. I see me upgrading the 1.0, as I am a believer in the High Fidelity products. For now, I have to let the bank account recover.. : )
