MiniDSP Flex HTx

Have been watching this thread interested in the HTx. Have had it for a couple days now. Have it paired with a Buckeye 3 channel Purifi 2nd gen, Q Acoustics front 3, SVS sb1000 (3.1 only) and a Win 11 PC that I use a source. In the PC I have a Sound Blaster AE9 with Sparkos 3602s which I think sounds amazing on 2 channel. I was worried the sound would be diminished by adding this in the chain. Happy to report that to my ears it doesn't, transparent. As measured, what goes in comes out the same. Thank you to the testers and moderators for making this resource available. This heavily influenced my decision to get this processor-- and the Buckeye. Couldn't be happier. Thanks
 
For those interested, I did a bit of testing last night on my AppleTV -> Flex HT setup, which I mostly use for Apple Music streaming with a 4.0 speaker configuration.

An earlier theory I saw was that if the AppleTV is set to output LPCM, you only get the so-called bed channels (ie up to 7.1) decoded, and not non-bed objects. While watching a video on mixing music for Atmos, a producer/mixer who seems to be doing lots of Atmos mixes mentioned that they didn't use the bed channels for their mixes.

This made me curious, so I found a test album (search for the Dolby Labs artist on Apple Music) that contained object-based test tracks, with objects moving around. They play back correctly on my system, within the limitations of my actual 4.0 setup.

So in summary: my position is that although you can't get discrete height channels decoded as LPCM from the AppleTV, you are not missing any audio that is encoded only in Atmos objects when using a setup like this.

(Hope that link works.)
 
I thought this was the solution to my use case. Turns out I was better served by a MOTU 828 controlled with Gig Performer on a Mac.

So...

I have a never-hooked up unit waiting for a new home.

PM if interested? (Gonna list it on eBay.)
 
Was able to get $750 on eBay in just a couple days.

Anyone interested in what going down the audio interface rabbit hole (like MOTU 828) involves, ping me.
