I was wondering if a pre/pro or receiver makes a big difference if it is THX Ultra 2 certified or whether it has been certified at all by THX. I have been looking at the Classe SSP30 which is not THX certified the Classe SSP60, The B&K Ref. 50 and the Denon 5803 which are all THX Ultra 2 certified. Is there a huge sonic difference when using THX. I currently own a Denon 4802 which is THX certified and I listened to a non THX movie last night and changed between DD and THX and too be honest I could not tell a difference. I like the Classe SSP30 for $3K vs. the others because of pricing and sonics. But I will consider spending more for the Classe SSP60 if THX Ultra 2 is worth the extra 2k. Please educate me.
