I think I agree with Sdcampbell ... I have not been able to hear much difference between my Marantz CD67SE and an expensive Meridian player I borrowed, and certainly not a $2k difference. In my experience the interconnect makes more difference than the CD player. I have a modest system of Densen B-100 amp and Spica Angelus, similar in price to the Soliloquys. Therefore your dealer could well be truthful .... I too have long suspected that high-end CD players do not justify their price tags, but I have never heard a dealer say so. On the other hand putting more money into the amp and speakers (and room treatment and cable) makes a profound difference (again my experience).
Patmatt is also correct that you should go with your ears.
Sorry I can't help with comparisons with the Arcam and Rega ... and at that price point I would also consider the Creek CD43 (not because I've heard it, but because lots of people seem to like it). I also wouldn't rule out Marantz ... I've been very happy with the sound and build of mine, and it only cost me $250 at a sale ... leaving plenty of cash for the rest of the system, and for a later DAC (if it makes an audible difference)
