I second Arkio
I am very familiar with Sim and find the sound truly first rate.In fact one of the latest reviews of the w-7 suggest that it maybe one of the best amps out there.The Lynx circuitry in the Evolution series is one of the most refined in existence ( more refined than the advanced Renaissance that was in the Moon series).I am sure that the Ayre is very good and it probably comes down to taste and preference, so listening is of paramount importance.Enjoy the hunt Dennis
