Hi:

I have an Kenwood KA770D integrated amp (14 yrs. old).
It has 80 watts per channel min rms, both channels with no more than .055% THD.
A dampening factor of 500 (50 hz into 8 ohms). Maximum continuous output 1khz at 4ohms is 120w.
Dynamic power of 190w per channel at 4ohms.
Total harmonic distortion at 8ohms of 93w + 93W. Power bandwidth of 10hz to 45hz at .09% THD into 8 ohms.
Signal to noise ratio of tuner/aux/tape at 108db.
It has 3 dat/tape hookups, phono, aux, tuner and cd.

Now, I want to know is it worth keeping this amp based on above specifications because it has been working well and buy the 60s or put money into a new integrated amp and but 22s?

Thanks
