My 15k multichannel setup beats the living daylights out of 100k+ 2 channel setups i have/had. 2 channel setups will have you chasing your tail forever. It’s the very nature of 2 channel setups!Boasting is not an idea....
I dont doubt that your multi channel is right and wonderful...I believe you completely till proof of the contrary...
But 2 channel acoustical embedded right with passive acoustical treatment and active one like with Helmholtz method could be so good that the sound upgrading obsession die...Then advising all people to trash their 2 channels for a fad of yours , so good it is, is not an idea or a possibility for almost all people here...
It is my case like many others who own a 2 channel system done right and by the way i am proud to boast about my 500 bucks system that tail behind anything at any price for musical pleasure ( not soundwise for sure)...Not because of the gear but mainly like a results of adequate controls in his 3 working dimensions...
Price has nothing to do with accoustic, nothing at all, save for sellers....But i used only homemade stuff...
