All I can do is just "echo" what has already been said about this thing. It oozes vintage soul and you can easily lose yourself in it. Plenty of options to tweak your way back in time. Definitely not just another delay, it's almost human.
Do you remember the astounding David Gilmour's guitar echoes in the very long track of the same name in the album "Meddle"? It was THIS echo unit! The Binson Echorec 7TE. It was also the echo unit used on all his albums by T-Rex.
And this emulation made by Audiority is wonderful. It runs in the same league as Nomad Factory's 80s Space which emulates the famous Roland RE-201 echo unit. Both are probably the most accurate emulations of these two legendary vintage echo units.
The most fun you'll ever have with a delay. Make any sound into Echoes T7E, get it looping, work in some AudioThing Outer Space (another nice RE-201) and throw on some Valhalla Shimmer and twiddle away.....for hours! An easy 5 stars. Audiority's reverb unit is also worth a test drive.
