Weiss 501 upgrade to 4ch

Has anyone upgraded their 501/502 to the new 4 channel version. If so, have you heard any improvements for 2 ch listening?

Four official languages in a country slightly larger than Maryland, so they don’t like simple. Postcard land with funny cheeses. Love my upgraded 501 and I’m the only one needing that satisfaction. Not looking, just enjoying. They got it right.

I recently bought the original 501, and it's really good in my system. Celtic66- I think you offered good details of your positive impressions you heard in the Mk2 upgrade, enough to encourage me to strongly consider the upgrade. dhali777- Could you post your impressions for us? Has anyone else performed the upgrade or compared the original 501 to the updated 501 Mk2? I find very few postings on the internet about actual listening comparisons, which seems strange. Thanks for sharing any experiences.
