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.
