Audia flight vs SimAudio phono stage

I have an opportunity to "upgrade" form the SimAudio lp310/psx combo to an audia flight phono. The Sim is just so good, dead quiet, I wonder if anyone has had a direct comparison. The reviews of the AudiaFlight have been very favourable, and since I will not have a chance to audition, I hope to draw on the experience of the forum. (I withdrew form the deal on the 2nd hand, faulty, audiaflight, so am now thinking full retail for a new one)
