A new Rega Aura or a used Rega iOS

Hi,

Finally getting back to having a proper analog front end after almost 10 years, moving abroad, kids....

Auditioning and really enjoying a Rega P8, using the basic Fono Mk4 phono pre, awaiting an Aria and seriously considering an Aura as I’m also seriously considering a P10.

My local dealer is willing to offer a fantastic bargain on a new Aura, about 30% off retail, still about 4k, but I could pick up used Ios (didn't check stupid spellcheck for post title) for less than 2k.

Hoping to get some advice/feedback/opinions from folks that are familiar with these specific units, no need to offer advice about other options, brands etc., this is a very specific inquiry.

Thanks in advance, good listening!
