* Voodoo cables vertical right-angle 15 amp IEC adapter, allows PS Audio Perfectwave AC-12 connected to MM27 (anyone interested in this, might check the second post on my review of Sound anchors for MM27).
These adapters does not appear to implement any audible flaws.
* Kemp Elektroniks S/R plug (Shumann resonator).
Still looking for an alterative PC for Wadia. Sablon Audio Gran Corona is a top contender.
