break-in for Marantz SA-7S1

Heard a marantz SA7S1 at RMAF.. . from the time it had 0 hours and was just pulled from the box, to when it had about 100 hours on it. Remarkably good sound for a brand new unit and kept improving all the way. . . I would expect that complete break in would take about 1,000 hours. Be patient and do not succumb to Premature Upgraditis Furiosa. G.

my friend owns a 7s1. i own an 11s2. i was advised to allow at least 500 hours before serious evaluation.

i think both players need an upgrade. both players are too focused and unantural in their presentation of timbre.
perhaps, a tube buffer stage would be advisable and/or a replacement of capacitors.

Upgrade? Given the cost of these units, just dump them and buy something 'out of the box' perfect.

Mrtennis, You seemed to have listened to a lot of different CD players ( from your posts ) can you comment on which one's may have been your favorite to date and perhaps what you liked about them? Thanks.
