Is EquiCore Deep Core a Great Benefit When Used With Core Power 1800?

The EC 1800 alone significantly improved the SQ of my system and adding the DeepCore resulted in improvements in specific areas. Low-end seems to have more extension, I think it's really that there's better quality bass, it's fuller and more defined. Jazz bassline now cuts thru and takes its place with other instruments. With rock, more separation and definition with bass and kick drum.
My system has excellent 3D imaging, adding the DC brought out the subtleties of instruments throughout the soundstage, there's more inner detail. It's noticeable in classical that is not over-mic'd. 

I'd say go for it if you can get it from Wally at the sale price. And his power cord works very well between the two units. I tried a few different PC's and his had the best synergy. 

Thanks @lowrider57 . I agree that the 1800 made a noticable difference in my system too. Guess it's time for the deep core. Better let my wife's head quit spinning before I get it though. I've been going through the kids inheritance pretty good for awhile now. She likes the benefits so far though.

Your system is beautiful, it deserves the DeepCore. Tell the wife you got it on sale. 

@lowrider57 
Thanks for the compliment. 
 Fwiw I always tell her that. It will go in the back of the rack so she may never know....well, unless I forget and bring her the cc bill.
