High Fidelity MC.05 Helix plus just

I have been using them for several years now and each time i add one the sound gets better

I recently got one of the Helix Plus units on a lark, after Rick listed some discounted units here on Audiogon.

I have to confess: I pretty much did not believe that this device could have much of a meaningful effect. I won’t go as far as saying I thought it was snake oil, but I really was prepared to declare that it has no effect.  I plugged it in and promptly forgot about it.

Well I’m here to tell doubters and naysayers that these do have an effect. I had forgotten I had installed it, and the next time I fired up my system I immediately noticed it sounded different.  I was wondering what was going on before remembering about the Helix Plus. The sound was a bit cleaner, blacks were somewhat blacker, and the whole presentation was a bit... softer and lusher.

My conclusion is that these definitely do something, and whether you like what that something is depends highly on your system and taste.  But there is no doubt to my ears of the effect.
