Viridian, is your sound system outside?
Preamp - what's the purpose?
Intentionally dumb question...
I've heard various 5-15W tube amps in my room. EL84, 300B, etc. They all have input stages and the output stage. I send them a line-level signal from a DAC.
Sitting a few meters away from my loudspeakers, the first watt alone gives me roughly 80db of volume. I think these amps are biased to expect the line level signal directly. Why wouldn't the designer do that?
So what's the point of adding a pre-amp? Why do people do it?
thanks in advance

The signal coming from your source and being fed into your power amplifier needs to be in the sweet spot of your amplifier's sensitivity. Meaning that you are well above the noise floor of your amplifier, but not approaching the output clipping level of your preamp or DAC device. Here is an interesting paper on the topic: Gain Structure 101 |
@mbmi The BEST sound comes from. TUBE PRE and a SS amp. BS. I had a SS amp. A Krell FPB 600 and an ARC Ref 6se . Now I have the ARC Ref 750s mono blocks with the ARC Ref 6se. Can’t compare. |
