looking for a quality integrated that allows for bypassing of the preamp section

In a simple A/V 2-channel system, I run an Upgrade Co. modded Oppo BDP-83SE directly into my amp, which is currently a Cambridge Audio 840W.  I prefer the extra detail and transparency that going preampless offers but occasionally find the output on some movies too low, even with the volume full up.  I've thought about getting a simple preamp (Parasound zpre) and connecting just for those hard to hear movies but that seems like a real hassle.  Also considering a Creek Destiny integrated that allows for either passive or active preamplication but may need more power than the Destiny offers.  Perhaps the simplest solution would be an integrated that has the inputs that allow one to bypass the preamp and use the integrated solely as an amplifier (what's the term for this input?).  What feature would I be looking for and could I get some recommendations up to $1500 used?  Many thanks.

Looks like the Pass Labs Int (integrated) series have preamp inputs, so you can use it as a poweramp.

The more I deal with rebuilding the vintage equipment, the more I'm sure that it's the BEST bang for the buck. The parts used in these units do get old, but replacements are available and they could be serviced to the original specs or better.

Yeah, there's certainly an avid group of vintage fans.  I had a buddy with an old Sansui integrated who played vinyl exclusively on Def Tech BP-8 speakers to very good effect.  Compared to my system, his was lacking detail and focus but it was always warm, and full-bodied, and very holographic and most importantly, satisfying.  So maybe you have something there.  Thanks.

And George, if I could afford the Pass or Gamut integrateds, I'd already have one of them.  They're both at least 2x what I could afford for this second system and I'm quite pleased with the big tube amp I have in the main system.  (Maybe I should just get that second job, upgrade to my heart's content, and then go from there).  Thanks for the good advice.

I indeed found heaven with my electronic repair tools and I pick up that skill every unit I go through. It brings the joy working on these with FULL detailed service manuals of vintage audio components available at hifi-engine that often show details on how properly calibrate stages after repair!
I’m on project now repairing Sansui G-9000 which is extremely complex..
Prior done with Pioneer SX 636 that sounded very close to tube amp after restoration -- extremely musical and clean.
I started from my friend’s Accuphase E202 that had uneven channels in preamp section and than fully restored unit with new and less noisy power transistors and filter caps.
Did lots of side by side comparisons of modern and vintage restored units and more often than not I give my preference to vintage audio and one of the vast reasons that it’s serviceable and service manuals are PUBLIC and not secret. Another reason that these units had been manufactured by far more honest industry than today’s high-end audio that is rather boutique than functional.
