Best ARC Integrated CA-50 or VSi55?

Has anyone owned both of these...or at least listened to both? If so, which is the superior unit?

Hi Whatjd I have had both & VSI55 is more to tubey & maybe a little lifeless. The CA-50 is more to the lively side. I mutch perf the CA-50 A great peace. Sorry I mist your post.
