I would say yes. Ray Samuels recommends 100-200 burn in time on his amps. Once my Protector settled down I would never use another amp and I will never listen unbalanced. All of Ray's amps have a great tubey sound to them.
I also use pure silver OCC cables and silver LOD.
The person to also ask is M_Coupe he just bought the RSA Intruder to pair with his SE846 with OCC silver cables. My burn in was a year ago but his is new as of about a month ago.
Thanks for your reply. .went for the international. .cant stand the long burn in time..
