Hi Brad, Felipe,
Thanks for the posts!
I am very excited about RMAF, and so are David and Martin, and I think this could be a significant turning point for Aspen - an acknowledgement that the next steps are marketing oriented. I certainly have sufficient products now.... It will also be the first time in my life I've been to the US, JUST in time I flippantly suggest before the artificial knees kick in!
I'm reluctant to compare my power supply to Wayne's. The name does indeed reflect the imaging qualities. I greatly respect Wayne, his update/refinement approach is fantastic, but yes, we've compared the H3 to a Bolder Cable supply of about 15 months ago, which is somewhere near the mark. It compares very favorably, but I won't comment further.
The Hologram 3 brings sonic improvements which literally leave your jaw on the ground. I know very well how the supply operates - I designed and refined it over a long period - but the subjective effect on the music is something else again which defies comprehension. Most linear supplies use feedback to control voltage; this circuit does not, and so there cannot be any damped overshoot characteristics or slew rate issues. Regulation is done in real time rather than after the event. Impedance falls with rising current and speed is in the MHz range. This appears to be the clue to what is going on. Dimensioning is extremely critical and must be tailored to the current draw very carefully. I'm very, very pleased with it because it's unique and works so incredibly well. I intend to bring quite a few to RMAF, and run a continuous, dynamic demonstration with a SB for all to hear.
Thanks for the interest!
Cheers,
Hugh
