I gotta admit that the tube audio was much more pleasant to listen to as compared to the solid state rigs.
The tube receivers had audio output stages capable of several (> 10) watts output - typically run in class A or AB. Modern solid state receivers are generally more limited in output (the K3 output amp is rated for 3.1 Watts into a 4 Ohm load). When the solid state amp is run anywhere near the power output of the tube amplifier the THD+N rises dramatically. For example, the K3 audio amplifier is already 1% TND+N at just 1 Watt into an 8 Ohm load! Put a quality 25 W (per channel) amplifier and pair of 8" diameter speakers on the K3 and I suspect one would be hard put to distinguish between the S-line receiver and K3 receiver in terms of tonal quality and distortion. The K3 would certainly have fewer RF/IF distortion products. 73, ...
