My experience is componets on initial startup will sound very good but bright and brassy. Then turn dark...closed and fat. Especially if the NBS cables are new...but the amps will continue to morph also. 100 hours should do it and be a lot better.
Jeff Rowland 501s burn in ... a strange experience
I have received today my monoblocs 501 and borowed a ML 39:
ML 39
NBS monitor III
Capri
NBS Monitor III
monoblocs 501
NBS Monitor IV
Infinity Renaissance 90
around 2:p.m (Europe) I have installed the system:
sound very detailed, beautifull soundstage imaging & focus, great energy,
on the negative side, some high frequencies too harsch a little bit venomous
6 hours later (system working all the time) complete change ... do the monoblocs suffer jet lag? ... ;-)
the sound has become very fat and heavy, has the energy of a sleepy hypopotamus, everything is slow, too warm, without focus, like coming from bad tube components ...
from one extreme to another... how is that possible, so extreme, I am ???
any suggestions?
thanks
