Active and passive preamp in one chain ?

The only input impedance I can find for your amp is 10K ohms. That's pretty low and it will cut down on your choices for a preamp. Also, if the amp section is designed for a passive pre, the voltage output of an active pre could very well overload the amp. I would write to Redgum and see what they have to say.

I see. So what kind of active preamp do you think would work? I am not technical, don't really understand this stuff. To write to Redgum is a good idea unless they get upset by the fact that I think that there is not enough overall gain in the integrated.
Not that I have a big problem with the curent phono/deck/Redgum set-up, except that I do lose some resolution. Otherwise the amp is quite good. And I do make recordings from records onto tape from time to time. I just thought that something inexpensive but reasonably good, something like Rogue, might temporarily make things better until I am ready to overhaul the entire signal chain.

@inna  I took a quick look at The Rogue preamps' output impedance and they all seem low enough that impedance mismatches shouldn't be a problem. It looks like your idea should work, it just seems so unusual. I'm not a tech guy either, and I'm not sure how trying this would actually sound. Is there any other phono preamp that could give you more gain? I'm sure there are others on here who could give you much better ideas than I.

I used to have a Redgum integrated too, and the people there were extremely nice and helpful whenever I wrote them. They may have some sort of simple answer to your problem. Good luck.

Xrayz, thank you very much. Yes, Lyndy from Redgum is very nice, I talked to her a few times. I'll talk to them.
What did you upgrade to from the Redgum?
No, I only have my AcousTech phono designed by Ron Sutherland which I think is very good but not flexible, you can either set it to MM or MC. I have no plans to replace it until I have a few thousand dollars to get a great tube phono stage or at least Gryphon or Sutherland solid state.

I went to a McCormack DNA-1 and I think the little Mapletree tube pre, don't remember the model right now. Then a lot more tube preamps and a couple different power amps along the way. Now I'm back to an integrated lol.  (Music Culture 701)

I misread.  sorry. i missed you were playing vinyl.  its not passive vs. Active, but that you lack a phono stage, or phono preamp at all.

These are funky beasts.  not only do they provide high gain, they must equalize the sound.  the eq curve is to minimize noise from the vinyl and dust. 

Phono stages imply they are active because of the ggain and eq.  lots of integrated amps and preamps include the phono stage, which has dedicated in and outs.

Sure I got phono preamp, Acoustech, then the signal goes to the deck, then to the integrated that has a passive preamp section.

Try a tube buffer from Musical Fidelity or Yaquin.
