Levinson 383 or Rowland Continuum 500

I have heard that the break-in time for Continuum 500 is somewhat shorter than on most other class D amplifiers, possibly because of its slightly higher operating temperature. Never the less, I suggest to be generous with break-in time allocation, and to continue the process for perhaps 300 hours. . . and then determine if there are any further changes up to 500 hours. DCSTEP reports that this break-in extension may not be necessary. BTW, one of the nice things about JRDG gear is a very long 5 years warranty on new units. G.
