I watched Dune the other month and was, almost literally, blown away by the audio. As a result, I started thinking about what my "affordable dream" home cinema set up would actually consist of. I'm now very far down the rabbit hole and hoping for some alternative perspectives/opinions.
Firstly, my current system is as follows:
Netflix/Disney+ and movies/music on HDD --> Raspberry Pi 3B+ and Allo Digione (S/PDIF out) running OSMC (primarily) and Volumio --> Mytek Digital 192-DSD DAC (Mastering Version) --> Genelec 8040B speakers (2 off). Screen is an old computer monitor (2nd hand/free).
Both the Mytek DAC and Genelec speakers were second hand from ebay. I've had the system since ~2017 and it has been and still is great.
What would I want a surround sound system to look like? Here are some constraints:
1) Budget ~£15k but it can't all be spent in one go. I'd have to build the system over a period of 5+ years. i.e. yearly budget ~£2k max.
2) Projector for visuals.
3) Genelec's or other powered/active speakers. I really like my Genelec's even though I was originally going to get Focal Shape (brand-new). Pretty keen to stay within the Genelec family (The Ones!) but open to suggestions.
4) Raspberry Pi running OSMC as the source. I like the Pi and the "simplicity" it offers and am happy to tinker. I am open to alternatives if they offer similar simple interface. I'd ideally like to stay away from smart TV's and the like. We don't watch live TV at all.
5) Dolby Atmos / DTS:X capable (this is the end-goal...will I ever get there or actually feel the need? Only time will tell...)
6) Future proofed hardware
7) 5.1.4 speaker layout as the goal, maybe 7.1.4 as a longer term aim
8) Simplicity of overall system / minimum number of boxes / limit amount of duplicated hardware (i.e. DAC/amps in an AVR and also in Genelec SAM-enabled speakers)
A few of the things I've learnt over the past few weeks of trawling through the web:
- sound cards that feature AES/EBU output don't have drivers for Linux.
- fitting a round peg (OSMC) into a square hole (delivering multi-channel digital audio to speakers) isn't as trivial as one might expect (perhaps I'm just naive haha). OSMC is Debian/Linux based and currently only has versions suitable for ARM processors. Even if an x86/64 version existed, it'll still be Linux based and drivers for sound cards likely won't be forthcoming
- It doesn't seem to be possible to decode Dolby Atmos or DTS:X except by using an AVR. Gotta love big business...
- Is Audio over IP the future for home theatre installations? Probably. The single-cable simplicity is an installation dream though obviously max. power cabability is limited. The new Genelec 4430A look great. But, sound cards for AES67/DANTE don't seem to be readily available with Linux drivers or for ARM processors.
So, some specific questions for the forum:
Q1) Given the above constraints, what system would you build and in what order? (Ignore room size and assume room treatment comes from another budget haha.)
Q2) What do you think is the future of AV/HiFi connectivity and user interfaces in the next 5 to 10 years? AoIP?
Q3) Are there any major downsides to delivering analogue audio signals (from an AVR) to speakers such as the Genelec 83XX series? (Aside from the obvious duplictaion of hardware i.e. paying for kit/capability that isn't used).
Q4) If I ultimately have to use an AVR with preamp line outs, is there any benefit to getting Genelec 83XX series over 80XX series? i.e. is the AVR room correction software good enough?
Here is the system I've tentatively decided:
Year 1: sell 8040B's and replace with 8330. Keep Mytek, RP3B+/Allo
Year 2: replace Mytek DAC (maybe sell?) with Mutec MC-3+, GLM set and GLM remote volume. Swap RP3B+ to RP4 and use USB out to Mutec. This gives a stereo system that is all digital to the speakers.
Year 3: add 8331 centre channel. I think this is usable despite overall system only having a single AES/EBU channel. Mutec --> Centre (summed) --> L/R
Year 4: add second 8331. Reconfigure system to use 8331's as L/R and single 8330 as centre. The second 8330 is now not used.
Year 5: add 7360 sub. I think the system will still work with all digital signals. Mutec --> sub --> C --> L/R
Year 6: add Genelec 9301A networking and MiniDSP U-DIO8. The Mutec is now no longer used. Shift 8330's to be located BL/BR. I now have a 4.1 system.
Year 7: add 8331 centre channel. I now have a 5.1 system.
Year 8: is there really any point planning this far ahead... To get to 5.1.4 I need to replace the Genelec 9301A with a "proper" AVR (with analogue preamp outs) and obviously get the extra speakers (which could be 8030's or 8020's?). Reconfigure system so all surround speakers use analogue inputs (from AVR), re-introduce the Mutec into the system for the L/R speakers for stereo listening (is this even possible? 8331 only has single input shared between analogue and digital). RP4 feeds Mutec via USB and AVR via HDMI.
The total spend from Years 1 to 7 is ~£10750 (ROM costs from https://www.thomann.de/gb/index.html), leaving ~£4k to cover the AVR, projector, four height speakers and all cables. Probably not quite enough... but ideally I'll get most items second hand.
Rationale for waiting so long to get an AVR (in the yearly plan) is simply that as technology continues to change, the longer I wait, potentially the "better" the AVR will be or the more options that will be available 2nd hand. Or, some of the hurdles I've encountered the last couple of weeks w.r.t. linux drivers for sound cards will just disappear/no longer be relevant ultimately resulting in a simpler system.
I'm interested to hear thoughts/comments/critisms? Can I do better for the same money?
