My main objection to vinyl is the ticks, pops, and noise.@cat_doorman A lot of ticks and pops that people react to when playing vinyl are caused by the phono preamp itself (due to high frequency overload) and aren't actually on the LP itself. Its a bit technically complex to describe quickly, but has a lot to do with the fact that the phono cartridge has an inductance and the tonearm cable has a capacitance- together they can create Radio Frequency energy that can overload the phono section's input stage for very brief periods- the ticks and pops. So if the designer didn't take this into account, you get more ticks and pops. And yes, most of the phono sections out there have this problem!
What am I missing? Pre/power gain and input sensitivity.
I’ve read a few posts about power amps with lower gain needing a pre with additional gain, but no one seems to mention input sensitivity in those conversations. If my source outputs 2V and my power amp input sensitivity is only 1.2V then whether the power amp gain is 16dB or 26dB my pre amp is attenuating the signal and the amount of gain on the pre doesn’t matter at all. With a given set of speakers, to get the same SPL with 2 different amps they should just need to output the same voltage, regardless of how they get there.
