Are sacd mods really worth the money?

I just got the Phillips 1000 at Tweeter and wondered if the mod upgrades on say , Reference audio Mods are worth it . It will cost apx 1200 $ to do their best upgrade. Should I just wait to get a used SA 1 or bite the bullet now with the mods .?. Playback system; Aerial 20 ts Aerial cc5 and Aerial sw 12 subs across front. Aerial 10 ts on rear. Meridian 861 -800 v 3 and 2 BAT 6200 multichannel amps bi amping all 5 . Nordost spms all around. Quattro Fils connect . . Already supoporting dvd a but stepping into sacd .Thanks for any help!!
