How large (or small) is the audiophile market?

I apologize but i did not target anyone and certainly not you...I was speaking in general...

@mahgister  you are calling me "the average dude will idolize A.I."?

@mahgister you mentioned you bought a LPS for peanuts. Care to share what it is?

It is very cheap but as i can judge (i am no specialist at all)  well designed but without on/off button which is not really an annoyance for me...

The cleaning effect is immediately audible in my low cost system...It drive my  speakers/dac 12 volt and my secondary headphone amp (5volt)..

I cannot help you here because i only used my hearing not electronic equalization of the room to tune my room and many mechanical tuned resonators that work on large band frequencies for absorption and reflection...

It was not esthetical  and not perfect but it was spectacularly good but it takes me too much time and effort and i will not recommend it to everyone save those who want to learn acoustics by -playing with it but i learned so much doing it i will do it again...

Anyway my speakers at the times did not go much  under 50 Hertz..

I fixed my bass by the placement of the resonators and their dimensions and adjustment...

I have a 10dB resonant peak at 40Hz How do I fix it?

Nobody wants to spend large amounts of money to listen to the crap they produce currently. (Of course, my dad said the same thing and probably his dad too.)
