[QUOTE="glennlewis, post: 1315162, member: 564701"] The reason some tube amps have only tubes in the input stage is quite straightforward...Because we all listen to digital music reproduction the sine waves of CD's and MP'3 tend to be only as good as the sampling rate. Because digital music has square waves instead of smooth sine waves which is present in live music the experts will say the music sounds choppy. I think it could be said especially in the high end (tweeter realm) that with low sampling tweeter can sound harsh. Soooo...What tube amps with tubes in the input stage do is soften the harsh digital edge of the sampling rate and in effect transform the square waves into much softer gently rising and falling sine waves...Hope this makes clear....My 2 cents [/QUOTE]
