KEF 107 without Kube

@roxy54 Let me help you understand a little better. Most "audiophiles" prefer the straightest less altered signal path as possible. They want to believe their speakers are capable on their own merits to produce an accurate full range of sound without "electronic" assistance.

Here’s an example for you. You test drive a corvette and OMG it’s SO much faster than you expected. After your drive you find out there are mods to the engine making it faster than the base Corvette should be. So to reproduce the same high/excitement, you too much employ similar mods... Many which come with downsides.

Lastly, don't come to this thread making snarky responses to people trying to learn. I'm sure your level of Audiophilia is beyond what the common man can understand which makes me wonder why you're wasting your time responding to a lesser experienced person like myself.

So once you found out he had the bass bumped up did you ask him to make make it flat and you didn’t like it then? 

@mofojo no because we were walking back to the car when I thought to ask. I've never auditioned speakers before where they EQ'd them so I didn't think to ask.  

Also, I'm getting such a good deal that they're easily worth the money even if I'm not happy with the sound.. I KNOW what they're capable of and it's pretty dang special.

Based on a picture of the rear, you certainly can use an EQ between the pre and power amp.  Remove the jumpers on the back.

If you happen to be streaming with Roon you can substitute the EQ's built in there instead.

According to John Atkinson ’s 1991 measurements, the KEF107 definitely need kube in circuit or some sort of EQ for bass extension.
