I’ll be blunt. Your $1000 budget will allow you to achieve a marginal improvement at best no matter where you direct the funds. It’s a waste of time and money. My recommendation would be to continue setting aside the the funds for a better upgrade, one that will be a significant leap forward. Like a used pair of speakers that retailed for $5k-$6k.
Improve sound
I have a pair of martin logan 40i. Blusound node most recent version. Anthem mrx 720. I have the speakers connected with bi wire blue jeans speaker cable. The blu sound via optical cable. I have about 1000 dollars. What could I upgrade. Thought about getting an amp like the parasound 23+ or upgrading the streamer to a cambridge. Please I would love some help/suggestions.
