Juliejoema, yes, i have noticed this also, but were you to move the HFCs much you might have to wait awhile to hear them as they were earlier. I left all of my HFCs unused for two months. Now three weeks since returning they are back. But every night they are ready to go in about ten minutes.
I would also add that I find it more than smoothness. Especially in live recordings, I am there. It is totally involving. I must say that I think the power cords are most important. I recently tried one on my Nantais/Lenco turntable. The Exemplar charged Portal pc had been quite good, but the HFC CT-1 UR pc just was a "wow", although expensive, improvement.
