Headphoneus Supremus
Dammit, I have to partially correct myself, and I am glad to have to do so... I have just received the iFi Power usb reconditioner. Also, I am using a filtered socket, for both the Metrum power cord and for the iFi psu. I am using the Forza Audioworks twin usb cable I have, from the iFi power cleaner to the Metrum. The improvements, combined, are amazing. The resolution and treble detail is much much higher. More interestingly, a layer of sound, listening to the AD2000, is uncovered. Soundstage is also wider and deeper. I am very very surprised. I must say, this is the sum of several changes: the power filter, the iFi, the iFi PSU out of the same filter... so I will need to isolate the effects of these things. The Metrum keeps retaining the same character but it is much bigger. The sound improvement is definitely better than when using the Audiomeca Mephisto and Belkin cable, at a friend's house, using a similar quality power filter. I will be adding up more impressions when I form them.
