Cheers, Guys... As you may guess from the time of this post, I've been up late listening to music, so I guess that says it all!
Yes, the SUT is excellent and pretty much everything I'd remembered it to be. It doesn't trounce the Lentek, but simply presents an alternative 'take' on the music. It may not be just quite as ballsy and up front as the latter, but the midrange is more open and textured, and the bass seems to be a little deeper and more rhythmic, with increased 'boogie factor'.
It certainly allows music to motor along in an informative and fun way! I'm also finding that it gets better the longer a signal is running through it, which I've found before with transformers, in that they sound better after 'warming up', so yes I'm delighted with the SUT, and the good thing is that unlike with the Lentek you're not worrying about batteries!
Darren, I think you'll like it
