Esoteric x-03 se vs ARC cd3 mk2

The ARC CD3 MK2 is still in production. Their new CD7 is in ARC's reference series line up and not a replacement of the CD3.

The CD3 is out of production as far as I know.

I beleive this statement is incorrect.

In any case, I have not heard X-03, but I do own CD3 MkII.
I like it a lot. I think it has a very good transport. The only problem for some people may be the fact that this is a top loading player. Aside from this, performance is really really good. Especially when run through its XLR outputs into a balanced preamp. To me, the CD3 MkII is a much better player than DV-50S, although I haven't heard this one in my system, I heard it plenty of times to come to conclusion about its sonic character. Very good player, but in my opinion not as good as CD3 MkII. If you have a lot of SACDs to play, then may be you should consider Esoteric. Otherwise, ARC player would be my recommendation for redbook playback.
Also, check out the review of ARC where it gets compared to separates as well as Esoteric X-01.

Oops, my bad Audiophile1. As you pointed out above , the AR CD3 Mk. 2 is indeed still in the Audio research catalogue, and it is described at:

Thank you for your responses so far. I am currently
leaning toward the ARC cd3 mk2- but I have the issue of
finding the proper cabinet area for a top loading unit.
Also, I am concerned about a possible upgrade or replacement by ARC in the near future.

there will always be an upgrade concern. Get your player used on a-gon, so you can sell it later to get the latest model. Nut personally, I think ARC will not issue a new player within a year or two anyway.
