High Fidelity MC 1Pro Double Helix Plus Signature

This is High Fidelity most power full plug in wave guide at this time. Was not sure what to expect. Since i have a lot of High Fidelity gear already in my system. It really took me for a surprise,  I can recommend it very highly. It will work well with all levels of their plug in wave guides. Adding greater detail with outstanding smoothness to your sound.
I had in my system for about 200 hours before i did any real listening. I had 3 spots where i could have plugged it in at. I liked it in one spot - plugged into the wall with my MC 05s on the front end. the second spot was plugged into my  Mc 6 Hemisphere power conditioner, which i now use as a power strip coming off of the plug for my front end. This plug as i said above has a lot of MC 05s plugged into it along with a few MC 05s Helix plus and 1 MC pro.  This is where it stayed. I liked it so much I never moved it to the 20 amp line for my power amp. The increase in sound quality was not small or a little bit in any way. Note decay and drumming, where noticeable better at about the 225 hour mark. The tightness of the bass also increased (no bloat). As i approached the 300 hour mark highs became cleaner sounding with no harshness. The sound stage did not get any bigger or small for that matter. But was very detailed front to back. Like fine tuning  in a radio station to crystal clear. ( felt it was pretty good before). I will be adding another in the near future for the amp side.
