IMHO/ BACCH is without a doubt the single best bang for the buck thing you can add to your system (period)!
BACCH starts at $1K for what I believe brings the music to you in your home like you are at the actual recording, instead of listening to the recording through two speakers.
If you haven't heard it, you must, because it's a game changer.
https://www.theoretica.us/FYI/ Just traded up from the intro version and got 100% credit for what I already paid towards the Audiophile version.
While we are waiting for our Decware Sarah 300b amp, (two years now) we are using a Dennis Had 300b amp and that setup is great. We can’t even imagine how good it will sound when our Sarah comes home.
Just my thoughts,
