moving on from Emotiva UMC-200 pre/processor

Avo-
What good passive pres have you listened to?

By properly oversimplifying the initial signal do you mean properly preparing the input signal for the input of the amp? If not what do you mean by oversimplifying?

I do think I'll experiment, but am guessing already that the quality of a passive that I'm looking for will be too expensive. I'll probably start with a Placette Passive Linestage to at least see if I like it better than the Emotiva and then go from there by comparing with a good active in the same price range ($1500 used most likely).

Thanks,

"Just remember, you WILL be losing out on the dynamics side of things, in absolute terms, going the passive route with your thiels!" Why would you make such a claim, Avgoround? What can an active preamp do for dynamic range? It amplifies both signal and noise, so S/N is determined by the source. If the level of the source is sufficient to drive the amp to full output, as that of an Oppo BDP-105 is likely to be, I see an ideal preamp as a device for switching among analog sources and passing the signal without degradation. Of course, if you're into tone controls and such . . .

Ive used McCormmack TLC and Pass Aleph L passive preamps mostly, plus DIY passive volume attenuators and, of course direct DVD player to amp combinations mostly, for my passive experimentation.
Now granted, I've not played with passive setups in at least 8 years, honestly. But my experience with many amp and passive or direct combinations pretty much exclusively has always yielded me less than optimum dynamic results from the sound, and so I just gave up trying, to be truthful!
Now it may very well be possible that the combination of source components and interconnect cabling which I used, was running into impedance issues, and the CD players nowadays very well might be offering lower output impedance than previous units I experimented with (plus maybe I didn't consider restrictions from cabling being an issue there either???), allowing for better signal flow between the components, for more dynamically unrestricted sound, but I'd have to go back and experiment and research some more. Dunno.
I was reading a recent article where more than a couple of posters stated they also experience a " loss of dynamics and some compression in the audio signal going passive,too! So I definitely know that others have had similar experiences as I had in the past..so it's not just me! However, why aren't nearly ALL magazine professional industry reviewers MAINLY using high end ACTIVE preamps as a reference in their own systems, if passives work and sound better/more pure sounding???! That makes no sense.
I did also read this article from a year ago, claiming that passive preamp require careful cabling and source component selections for good results from passive preamp, so maybe that's it.
Maybe I really DO need to go back to experimenting. Because certainly I'd MUCH rather be able to ditch a preamp in the chain altogether. If I can simply get the full dynamic capability from my sound, large open, unrestricted full soundstage that I've experienced with the best high end preamp I can get?! ..maybe my old Card as and Harmonic Tech interconnects were either not compatible with my DVD player n amplifiers impedance matching compatibility, and combinations were simply not compatible with each other? Hmmmm...
imma need me some more research n tinkering, I guess. If anyone out there who listens to occasional Metalica, eclectic world beat, hip-hop n pop, rock, and even movies through their 2 children system, and they exclusively use a passive front end setup with great dynamic results, in their opinions, ..lemme know what you are using in your setup, if you'd be do kind?!!!! I'd like to try out your combo, fer sure. Otherwise, my results of trying paramount amps w built in volume controls, high quality attenuation n DVD players w built in volume haven't cut it for me, compared to better active...is all I'm sayin.
Yes. I'm willing to be enlightened, otherwise, and shown the error of my past ways...

You're right. That is it. Passives can be great, but there's a lot of equipment out there that doesn't work well with them.

See if you can find an Adcom GFP-750. Its both active and passive, so you can switch back and forth between the 2. It also has a remote and is balanced.
