suggestion for a SS class AB amp that sounds like a class A ... if such a thing exists

Extra long speaker cables and extra long interconnects with high capacitance can be impactful. Particularly as noted earlier when gear/voltages are not designed to be used with long runs.   

A simple test is to pull all the gear super close together in a room, even with short low grade cables, make everything super short (for a test).  Listen and see if you can hear any difference.      

@soix @decooney @onhwy61 I just changed the cable going from the DAC to the Sugden and it did make quite a difference... next step, the cross overs... but that’s gonna take a bit more time... thx all...

@alaindexe
next step, the cross overs...

FYI, for some added inspiration - peeking over on the DIYaudio site, members were commenting about before and after results from upgrading and refreshing the old Altec 604/620 crossovers with GPA crossovers and replacement parts. Quote, "it added a sense of spaciousness and clarity to the speakers", unquote.

Rega has some nice integrateds.

@decooney I hear you... I used to have very good cross overs that a friend did for me, when I had Altec Stonehenge III (also with a 604 8G)... they we’re made with oil condenser and military grade parts and weighed about 20 pounds each... they we’re SO MUCH better then the junk that came with the 620A... I’ve been missing them greatly ever since... I sold the Stonehenge III because the inner volume of the enclosure wasn’t sufficient... I had to sell the cross over as well in order to get the money to buy the 620A... it was heart breaking because I built them myself (they were grooved)... but the 620A are MUCH better since they have the perfect volume for the 604 8G...
