Your helpful comments much appreciated!
Thanks, Sdatch, for the explanation about the Velocitor. Since there isn't a lot I can do about the power lines in my building, in spite of its sonic virtues this doesn't sound like the unit for me. You've helped me simplify my choices!
Thanks, Twb2, for the positive evaluation of the APS, which I think is widely shared. A friend tells me that one has just now come into the Audio Ark (which I'm tempted to describe as Edmonton's Temple of High End Sound) -- clearly a listening session is called for. I'll report back what I hear.
Thanks, Warren, for the endorsement of the Audio Magic. I should explain that my hesitation about its sound was based on a Stealth review of long ago, and I dare say to-day's Eclipse, not to mention the Transcendence, is something else again. I wonder if my limited mains access curtails the effect of the two power cords -- I've e-mailed to find out.
Thanks, Uru975 and Brainwater, for bringing Sound Application into the picture. Hadn't encountered this company before. Spent some time on their website -- great reviews. Ease, liquidity, black background? Yes, yes, and yes! Not clear on the difference of models, have e-mailed them, too, for more info.
Great responses, everyone -- I'll post again when something interesting transpires! -- Nick
