DAC OR NO DAC???

mbag

I hear ya. I just listen to relax with a glass a wine or two:) at the end of the day. I don’t want to be overly critical. If it sounds good to me I am happy. I definitely don’t want to throw money away. If I did go with a new dac there is typically a trial period so if I did not hear a difference I would return it.

Thanks for the input.

I was thinking of something close to what you have mentioned.

I don't know exactly of all the options I may have since I am not that experienced but I was thinking of leaving my existing setup as is for movies and upgrade my floors and go with a c2600 and a solid state amp ( or some combination that I can enjoy going and listening and researching till then at different shops) and set up another room that is available just for music where I could add the dac/streamer that you say would make a difference in a different setup or with an integrated rather than with my 7704. I will definitely research more.

Thanks for the input.

+1 @caphill -- never underestimate the importance of a good preamp, so it's good to hear you were already looking in that direction.  Goodonya!!!

Whenever you are ready for a DAC, I'll add the Metrum Onyx if you can find one used.  Lots of research and good engineering into these DACs, and the Onyx comes very close to their their much more expensive Pavane and uses a lot of the same technology.  It's an R2R NOS DAC (I think maybe like the Schiit Yggie?), which tends toward a more organic sound if that's something you're looking for.  Anyway, best of luck in your quest!

Or if you want a single unit solution that performs really well for both stereo music playbacks as well as surround movies (HT) I would highly recommend the Classe Sigma SSP mk2 preamp processor ($6k) or the original version of the Sigma SSP ($5k original msrp) that can be had at discounts (maybe around $3k or less) since it’s been replaced by the mk2 version. The mk2 version has upgraded HDMI and audio video boards to accommodate supports for Dolby Atmos, DTS-X, 4k video pass through.

You can sell your Marantz AV7704 av preamp processor. The Classe Sigma SSP is optimized for use as a high end stereo preamp for music playbacks. In the end you won’t even need to add an external DAC with this Classe Sigma SSP. For digital stereo music file playbacks you can run USB cable to its rear USB DAC input and its USB input sounded the best compared to its other inputs.
This unit is optimized for use with its USB input for digital stereo music playbacks. Its USB input implementation and configuration is very well designed and engineered.
For your AV or video sources you can still connect using HDMI cables to its HDMI inputs.

It is a bargain especially considering the price point and all the capabilities and functionalities that this unit performs. It is an AV preamp surround processor/excellent stereo preamp performance/excellent sounding when used its USB input for $5k new or less than $3k used.

And you can still use your McIntosh MC207 multi-channel amp to power all your speakers.

Op’s original budget for DAC was $500. I completely agree the Marantz 7704 preamp/processor preamp section will be the limitation of the system. Most likely the AV7704 volume control is done by an integrated circuit. But with $500 budget, I don’t see how that can be addressed.

I suggest save until you have bigger budget, then consider adding a dedicated stereo preamp with HT bypass followed by adding an external DAC.

My own journey of combining 2-channel with HT was a painful one (money wasted).  Eventually I settled with semi-DIY passive preamp (fully balanced silver autoformers for 2-channel with another 3-channel copper autoformers for HT channels, working as slaves and will follow stereo volume).  I use Oppo 205 analog outputs for HT, started with Oppo 95 initially, XLR used for main channels.  HT signal processing and channel balance all done in Oppo.  Whether in HT or 2-channel, it's always pure 2-channel audio quality.
