Tandberg sounds bright.

Just got a Tandberg 3026A 150X2 amp. After letting it run for 24 hours I gave it a critical listen and it just sounds forward and bright. I did have it worked on for a weak solder joint. One channel did drop out again but came back. Anyway, are Tandbergs all forward and bright or is this weak solder joint(and resistor replaced) causing this. I thought this was a very good amp. Comparing to a Bryston 4BSST. The reason I got the Tandberg is I could not afford one years ago and just wanted to own one now and see how it sounds. Any and all replies welcome about any aspects of Tandberg. Mike
