I have a TTouch attached to my SBTouch for the past couple of days and it's definitely a thumbs up. :)
I thought it would be a lot of money for a PS but decided to try and I am very happy with the results. A lot more detail, better bass and a great soundstage - Beethoven's 9th never sounded better ;)
Ordered direct from Teddy in Israel and he's been great - recommended!
