Path of signal from turn table to speaker

Hi all, if you could humor a fledgling "audiophile" still learning... can anyone specify how a signal get from a turntable to the speakers? My understanding is that pure analog circuits are for many reasons not common. This means that the signal must first be converted by an ADC (analog to dig convertor). This signal then travels through the amp circuitry and eventually reaches a DAC which then outputs to the speaker. Is this decently accurate?

The second part of this question relates to how an amplifier can affect this signal. I have a rega preamp so I don't need an amp with a phonostage. If this is the case I have a hard time understanding how one amp will differ from another for record playback. I know that amps all differ in there capabilities but the basic formula does not change. Analog signal to digital and then back to analog. When purchasing an amp for records... should i basically just purchase for that amps capabilities and nothing else from the input standpoint?

Forget DAC and all digital for a minute.
Phono amp > Preamp > Power amp > speaker.
All of these can be analog. In fact it’s preferable.
The phono amp is special. It contains equalization circuitry to compensate for the frequency curve needed to cut a record.
The Preamp drives the power amp and allows selection of sources. It can have a DAC built in. The pre and power can be together in an integrated amp.
