Is dedicated PreAmp with Oppo 105 needed?


I think I've a decent HT setup but still feel there's something missing. I watch movies 70% & listen to music 30%.

Since Oppo provides pretty clean sound, wondering if upgrading to a dedicated PreAmp will make any difference. If it does, what would you recommend in say $1000-$2000 range? I intend to bypass the Video & connect straight to my Plasma on HDMI 1.4a.

Thank you!

P7 and be done with it. Otherwise throw your money into a separate preamp and amplifier that kicks butt over your Parasound and Oppo stuff. Most audiophiles have a separate setup for music. HT Passthru is an option with the P7 to get the best of both worlds. Halo P51 can't hold a candle to a good 2 channel setup. Like you said, only 30% Music.
All, I appreciate this threat has been going on for a little while but as Krell S-1200 and Oppo-105D show both up whithout wanting to sidetrack - quick question: Has anyone managed to successfully connect them via HDMI (I use Kimber HD19). I get image but no sound, interestingly the same happens with my XBox One S (where I have disabled 4K Upsampling as well as HDR to avoid handshake issues). I get analogue signal from my phone pre-amp and realized that the display of the S-1200 does not say waiting for audio signal - anyone any ideas what could be off? Thanks. A.
How does Krell S1200 compare to Denon AVP-A1HDCI preamp for Analog audio? That's one beefy preamp.
