But thinks about it: it is as said scottwheel very well , an acoustic revolution not a new toy ... Not an illusion of Hi-Fi at high cost either ...
Anyone with already a decent room and a relatively good system can only buy that ...
The only equivalent upgrade will be old wax roll or disc compared to stereo vinyl ...
You know this if you had read Choueiri articles as acoustician scientist not as a marketer ... Scottwheel is right about what he said and own one ...
What will be expansive is buying anything else ...
People budget is limited, audio sellers dont goes bunker with this revolution because it will kill for many the upgrading high end market ...
If you own an already good amplifier, what is better for the S.Q. improvement to buy one 15,000 bucks more costly or buy the BACCH filters and keep your 5,000 bucks amplifier ?
Same reasoning about speakers ...
Any upgrade will be thin compared to this crosstalk compensation set of filters with no degradation but improvement in timbre experience and all the spatial characteristics ... No brainer...
The only thing as best as these filters and necessary, with them or not ,is a dedicated acoustic room ...
Theoretica is the only company, right? Yeah,hardware version sp horribly expensive
