The future of preamps


I still use one, but I wonder if their days are numbered. To those who have removed the preamp from their system, have there been any regrets? Anyone gone back to using a preamp after having removed it?

Atmasphere:
"The rule of thumb here is:
If you can hear differences between interconnect cables then the source is not controlling the cable."

Sorry, wrong again Atmasphere, the only time all cables will be made to sound the same/equal.
Is when the input of the poweramp is made extremely low input impedance as well, like 500ohm or less. And what's driving it (pre or source) has an output impedance extremely low like 1ohm or less so it can drive that very low input impedance of the amp.
This then will negate any differences in interconnect sound and they should then all sound the same.
The only down side is with that lower input impedance poweramp hardly any sources or preamps can drive it.

I'm hoping someone could figure out how to eliminate the power amp as well so I can find a different hobby.

I very much like the entry level Naim Nait 5i2 integrated. It does not have an active preamp stage. But as an integrated it can certainly "control the cable". That raises the question as what the advantage is of having an active preamp stage in an integrated amp.

And, as an extension, would it be desirable to have a high end amp with its own integrated passive preamp stage? That would certainly put the need to "control the cable" in one manufacturers hand and let it happen internally. That would take the passive preamp out of the source component as people are trying to do with their DACs today and put it into the amp. That begs the question as to whether it is desirable to have the greatest synergy and the ability to "control the cable" between the source and the passive pre or between the passive pre and the amp.

No answers here. Just thinking out loud.
