The Rothwells.
Now I've had them a day or so and listened to 2 different albums, I can say I'm pleased with the outcome. After the posistive review I gave after listening to the Martin Grech album, I stuck 'Silhouettes' by Textures on, and my heart sank a little. The sound had lost it's energy and pep. The detail and "quality" were still present, but it didn't get my foot tapping/head banging as it had done before the attenuators.
However......
After letting it play on a loop for a couple of hours while I was upstairs, I revisted Textures and re-listened to the whole album again. I'm much happier now. The vigour seems to have returned for the most part, and the previous improvement in detail is still there. Overall I'd class it as two steps forward, one step back. The benefits outweigh the negatives. Not bad for a relatively modest outlay.
I think I have to re-tweak my sub though, as it's overplaying at the moment.
