More space saving than cost saving, I suspect, since the mini-XLR connector is a fraction of the size of two std. XLR ins, and the MX-VYNL is quite small. But you are right, that mini-XLR is a problem. When I last looked, 2-channel XLR to mini-XLR adapter cables seemed to be rather nonexistent commercially. Like probably 99% of all TTs, my VPI TT has conventional unbalanced RCA outs, so I haven't had to directly confront that challenge. The VPI could, of course, be easily (but expensively...) converted to balanced connectors, but in part because of the lack of easy availability of the needed cabling, I haven't made the conversion. No doubt any competent technician handy with soldering (I am not...) could make the needed cable, but that issue remains as my sole and only complaint with the MX-VYNL.
BTW, since writing the review above I have used the MX-VYNL with an 8 D-cell battery pack. It works fine, but there is no perceptible difference in sound.
As for the C.E.C. PH53, I've no experience with it. Thus I really can't comment on it except to say that both on price and on paper they appear similar. However, the PH53 is apparently a significantly older model than the MX and it's from a much more obscure manufacturer. You might more easily find a PH53 at a good price used, but beyond that, your choice.
