Here is
RA-611, a truly sophiscated pre-main amplifier created for excellent stereo
listening, at surprisingly reasonable cost. Not only it hasinherited all the
outstanding performances of the predecessor RA-610,but also it is incorporated
with much more improved electronics. And
convenient features. The amplifier then offers greter versatility and
simplicity of usage not found in those at comparable price.
Think of its
modest power of 30 W x 2 continuous RMS both channels driven. The distortion
that is way below 0,1% at normal listening. The phono overload that is amazing
at 100 mV. And the power bandwidth that is really wide from 5 to 50,000 Hz.
Look at the controlsand the connections; you can play two tape recorders and
dub each other with a flick of switch, two record players, and two auxiliary
components. To suit your listening taste, thers are many controls for simple
operation.
