Dentons

All those brands and their entry level products are going to be bright sounding products. Not warm like you want. And yes, to get to better sounding products, you usually need to go up to the next series up (from entry level). Take a look at e.g. Wharfedale Linton Heritage (EAC review), Wharfedale S

Hi there! I also like the Denton 80th, even if they don't have the most neutral sound and some other shortcomings. One of those is that they have some noticeable directivity errors from about 600Hz upwards (mids, upper mids) all the way into the highest treble regions (20kHz). See frequency response

Second getting the Super Lintons. Or even the standard Lintons. I’ve had the Dentons and Lintons, Lintons were much better. You’ll get a much better finished product with Wharfedale for your money.
