I liked v14 over v15. And I think Cygnus is better than both. YMMV but if you are happy with v15, stay there! Or sell your III and buy the 4 or 5 amps you listed as being so difficult to dial in. Life is too short. Was talking to guy the other day who is only 72 and dying from cancer. He didn’t mention any regrets about not spending more time bitching about modelers vs amps ...
