Newegg has the CX550M on sale now for $30 AR. However, when you select it, it states that it's the "Classic Version". See this link for what I mean:

I only bring this up because when you go to the non-modular version's page, clicking on the CX550 shows that it's the 2017 version, not the "Classic Version". See this link:

I just want to make sure if I pick up the CX550M that it's indeed the latest and greatest with DC-DC and better build quality.
