Conrad Act2 serie2 or ET5 wich would you buy

HI...

The upgrade fever strike again, and I would like to hear about your experience...
I already own a Premier 14 for the last 12 years anda Premier 10 for 5 years before. Maybe I would like to try something new/else... I will stay with Conrad, so please dont talk me in something else...
I would like to hear about those who personally lived a few month with those two machine.
Someone just told me about impedance and his view was that the ET5 would do a better job with long interconnect (15 feet)... an other friend told me about those 6h30 vs 6922 (an other story).
Nothing to help me with my decision...
one tube vs four....
Act2 is way better to look at then the ET5
So, that is way now I am asking you fellon gonner...

Thank in advance for all your comment...
