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!

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.
Hello Hits,

     You really still haven't resolved your issue after about 4 years?

      I find this unacceptable and would like to help you finally resolve things.
     It seems to me you just need to buy a good new or used 2-ch stereo tube preamp with a HT Bypass switch and not a multiple channel preamp like some of the preamps (called prepros because they combine preamp functions and surround sound processor functions).  
     You have no need for this since your Oppo 105 will perform the functions of a surround sound processor and you just need to add the functions of a 2-ch stereo preamp for music playback.  A tube preamp will add warmth, texture and 3 dimensionality to your music playback and the HT Bypass switch will allow you to select surround sound playback from the Oppo.

     Please let me know if you'd like my further assistance.


Thanks,
   
 

@ noble100: Thank you for your consideration & reaching out to help.

There are multiple reasons why I haven’t jumped yet: 1.) I’ve limited knowledge. I came across very few multi-channel analog audio PreAmps/ PrePros (online) and even lesser number of comparison reviews/ opinions. 2.) I had some financial difficulties due to job loss & other factors. And I do recognize my budget is limited for what I’m expecting to achieve 3.) I’m extremely picky & would like to do things right the first time.

From what I’ve read, the sound straight from Oppo 105 can be very digital or clinical. That’s why, I’m looking for a Tube or Tube like sounding Pre/Pros that is good for both Stereo & HT (multi-channel) listening.

Not sure how a 2-ch stereo preamp with a HT Bypass works. But ideally I should be able to connect Oppo’s Stereo XLR/ RCA for music & 5 out of 7.1 RCA Audio for movies to my Parasound A51. Regularly toggling the "Input Select" switch is not an option. https://www.parasound.com/a51.php
