I've had many Denon TTs over the years. I have set up and repaired many more. I have never seen a GT750 and it is not listed in any of the catalogs I can find. some exist on resell sites, and it looks like it might be a European market version. I have used the Thornes although it was some time ago. Regardless, the Denon is almost certainly a direct drive and the Thornes is a belt. As you would expect, they product a different type of sound. I like DD for the drive and pace they offer, and often a more solid bass. I like belts for the openness and cleaner upper range they often offer. These are generalities as I've not compared these two units directly. Unless you have a chance to try both, it may come down to the sound you are after.
