Where to Connect a Phono Preamplifier into a Line Stage

Lol! They ALL have some inputs that "are more direct" than others! Look at the back- RCAs all in a row. Different distances from the selector switch. Are we now gonna quibble over one being 2cm "more direct" than another? Oh Lord, we are! Someone else gonna leap to defend them, posit something even less likely and a whole lot less relevant. Next thing you know GK, dajones be here quibbling back and forth. And that goes on for weeks, until finally one of them catches Wuhan or forgets to pay the cable bill and we get some relief. Oh well. Entertainment value. At least this time the OP got his question answered before the Samneric Show.

No mc, onhwy61 is not speaking of which RCA input jacks are closest to the selector switch on a pre-amp. He is referring to pre-amps with a "Direct Input", that pair of RCA’s bypassing any and all controls except for volume/level. ARC is one company who have made pre-amps with that feature (my LS-1 does, as did the LS-2 I once owned).

Bdp24 ..... +10.
Miller .......  -10

Also, some preamps (such as the Jadis JPL and JPS2) have an additional tube in the CD input circuit to soften the sound of CD players.  Not needed or desirable for phono playback.

It would depend upon the layout of your preamplifier circuit.

HWY61 is spot on with his response.
