Using the Thiels without the EQ is like buying a Maserati simply to drive to and from the supermarket - you may enjoy the ride but you'll be missing out on what the overall intent was in designing it. I am currently "driving" my 3.5's with a Macintosh Mc275 tube amp which, for some people, may appear to be too little power for what are legendarily "power hungry" speakers. I listened with and without the EQ in line and I can testify that the EQ is necessary. It could be my ears alone which detected better imaging with the EQ in, but that's my story and I'm sticking to it. I love these speakers.
Thiel 3.5 equalizer advice
I am using Thiel 3.5 speakers without the equalizer. Does anyone have any insights (or firsthand experience) on the overall difference in sound that results if I bought and added one to my system. Does it just impact bass response or will it impact other sound qualities? Does Thiel still make the equalizers? Thanks for any insights.
