Anyone still using monster M2.2S cables (the really fat ones )

Ive been playing with my power cables lately after picking up a Hydra.   Have been trying a few different speaker cables but I keep going back to the old thick monster cable.    Running upgraded Odyssey Monos with tube preamp and Dunlavy SC IV speakers.  Sources= mostly digital but also a few records now and then.  Room is treated and been tweaking it for the last 4 years.    I tried Groneburg,mid range nordost and cardas speaker cables.  Interconnects are all high end Groneburg.  Curious what the Audiogon community thinks on the Monsters.
