Just to throw it out.... I would look at:
- Magnepan .7s at ~$2000
- D-Sonic M3a-800S Stereo Amplifier (400x2 into 8 Ohms but stable down to 2) at ~$1475
- MiniDSP SHD (Streamer, pre-amp, DAC, lots of DSP options for bass management) at ~$1299
- SVS SB2000 Pro - ~$899
Total Price ~$5673.00
This is all priced as new and I think you'd have a very nice sounding system. Add a subscription to Qobuz and a NAS with your own CD rips and you'd have tons of music at your fingertips.
The issues with the above suggestion are:
- MiniDSP SHD can be a great streamer/preamp, especially if you want to use custom crossovers for managing a single or dual subwoofers. It even comes with DIRAC I think if you wanted to use room correction. But it would not be as "plug and play" as a traditional preamp.
- In addition, the MiniDSP SHD only has one analog input so you'd be limited on your sources. You could add a turntable and just use that as well as streaming. It does have a few digital inputs, though.
- The MiniDSP SHD would probably convert a turntables analog signal into digital so if that bothers you, it's not a good choice.
- You'd need a phono preamp to add a turntable, either built into the turntable or external. Schiit makes one for about $150 I think.
- You'd need a room that has space to support the Magnepans. Generally they sound best when you can bring them out into the room a few feet. So if your listening room is shared with other things, maybe not the most convenient option?
- You'd have to like Magnepan speakers.
- You don't need the sub. But, then again, you may want two. Just depends on if the Maggies satisfy your bass requirements.
- You'd have to like the DAC in the MiniDSP SHD. It is apparently very good but some people feel strongly about their DACs
- The MiniDSP SHD uses Volumio as the streaming software. I've used SONOS and BlueOS but not Volumio so I can't give you any opinion on how user friendly that software is.
FYI, right now I'm using a SONOS Port into a Schiit Modi3 with each channel going into the input of an SVS sub and then running the output of the SVS sub into one of johntwo D-Sonic mono power amps into some Maggie MMGs. Sounds good to me. I do have some 1.7s on order and will probably replace the Port with that MiniDSP SHD in the near future.
Good luck!
