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!

@ Kr4: "I got that. What else do you want it to do?"
I want to connect my Nakamichi Cassette Deck & want to enjoy a richer, warmer sound of Tube.

@ Willemj: Ripping the cassettes to NAS is an option but I’m keen on spending that much time. Besides, I love how the cassette assembly of RX-505 comes out & to see some moving gears.

I am willing to stretch my budget a little bit. 1.) How is Classe SSP-800 or something from McIntosh MX series or  Krell ( Showcase 7.1/  S-1200/ HTS) or Bel Canto (Pre6/ 2-3 units of DAC 2.7/ DAC 3), etc. whichever sounds better & can process relatively current Dolby & DTS format?

A Tube PreAmp driving all the HT channels will be cost prohibitive. 2.) Instead, can I just insert a Stereo Tube PreAmp driving the front two speakers & connect remaining directly to the Parasound A51?
3.) Or how about Modwright or other similar upgrade to Oppo 105?

Thank you guys!

5 months & no replies?

Anyways, I searched a lot for a decent multi-channel, audio-only preAmps. Apart from Classe (SSP-800, CT-SSP), Krell ( Foundation, S-1200, HTS) & a few McIntosh MX series, there are not many (desirable) options. However, there’s a lot of very good Stereo only preamps. And most have very positive feedback for Stereo only over multi-channel PreAmps.

Is there any way I can connect both, the Oppo 105 & Nakamichi RX-505 Cassette deck to the existing Halo A51 - 5 channel amplifier via Stereo only PreAmp to enjoy HT & Music both?

I might be overthinking here but I was wondering:
1.) On Oppo 105 can I use "XLR/ Stereo Out" >> to connect any Stereo PreAmp >> Parasound Halo A51 Amplifier & connect the remaining 3 channels (C & L/R Surround) directly to the Halo A51 (bypassing a PreAmp) to enable both Stereo & HT listening?
This way, I don’t have to buy another Amp for Stereo only and/or reach out in the back of the A51 to toggle "Input Select" switchm which is not convenient.

2.) Another option I was exploring was to connect Oppo via Toslink to a Multi-Channel PreAmp. But google search indicates that it does not have the bandwidth to carry the lossless versions of Dolby TrueHD, DTS-HD Master Audio, or more than two channels of PCM audio.

Toslink interface is BAD BAD BAD.  Don't use it unless you absolutely have to.  Digital COAX is always superior for any digital audio.

That being said, the Krell S1200 is a great preamp/processor, but only if you mod the power supply by soldering in huge 15,000uf capacitors.  The stock power supply is undersized, in my opinion.  Stock, it will give good sound, but it's a bit thin/bright in a way.

You are correct in that putting a preamp between the Oppo and the A51 can be done to improve 2-channel audio.  Look for one that has a HT bypass input, so that you can still use volume control from the Oppo.  What is your budget?

No- they have to be switched separately so that one source does not load the other.

@auxinxput: If I’m using S1200, I don’t need to use the Digital COAX. I can use the XLR/ RCA too, right? And wouldn’t that be better?
Do you recommend S1200 over other Classe & Krell Multi-channels preamps?
Do you know what type of capacitor will I need? Is it an easy switch? It’s been a while but I think I can do a bit of soldering.

@atmasphere: So basically, I will have to buy a preamp & a dedicated amp just to play the cassettes on RX-505 in Stereo only mode? Well, that sucks. In that case, it’s better to get the multi channel preamp. Hopefully, it won’t compromise the sound so much compared to Stereo Only.
