Which leads me to ask why were ARC using totally inferior and poor quality capacitors, internal wiring and other parts in the first place??
Plus, how did such amazingly new caps, internal wiring and other parts suddenly become available!
This marketing technique has always been a MAJOR turn off for me with ARC gear. IF--if such improvements are made over a large period of time, this I can understand and totally accept, but with such consistency and in such a small amount of time ( just a very few years with the Ref5 to Ref5SE and so many others ( Ref 6 to Ref6SE...how long??) ( as ARC has always been able to do...looking back at their history) ---that doesn’t pass the smell test, IMO.
