Yes, you can affect fullness of the sound, which I would call a warm, natural, and revealing midrange and mid-bass. We do not often think of 'revealing' as applied to mid-bass, but it can be a real consequence of removing RF noise.My point is that achieving this tonal quality requires reducing the effects of RF noise in your whole audio system and in your house wiring. A single power cord change may modify the RF noise environment, but cannot resolve all RF noise problems. Hence my recommendation of Alan's Hammond choke tweak (the parsimonious audiophile's version of the Richard Gray Power Station).
All electrical cables that are terminated in mis-matched impedances act as filters, so that includes just about all audio power cords. The filtering action may not be what you want, however. Low-loss cables with severe impedance mis-match terminations are high-Q resonators, and the resulting amplification of selected RF tones (in the VHF and UHF bands, primarily) can cause significant problems when these tones intermix with the audio signal. They result in spurious audio-band tones that mimic overtones, but are not musical because they are not necessarily even-order harmonics of the musical fundamentals. They cause a dry, disconnected midrange and a veiled mid-bass, as well as excessive treble energy.
IMO, cables with lumped-element filters built in to them are not successful because the remaining segments of the cable act as resonators.
