Classe SSP-60 or SSP-75, SQ wise which is better?

My next step in my quest for audio nirvana will either be a Classe SSP60 or a Classe SSP75, of the two can anyone comment on which unit has better SQ in both 2channel and HT application?
For two channel go for the SSP 75.
Thanks Rugyboogie,

any known issues with SSP75 that you know of?
I good friend of mine has had his years with no problems what so ever.
It does not have the decoding as some of the new multi channel gear , but for two channel it is out standing.
