Hi Tennispro,
I am also a tennis player. I have had the W-3, the W-5 and now I have the Titan. The W-5 is better than the W-3: more power obvioulsy and also more refined. The Titan has the same signature than the W-5. I would say it is at least as good and perhaps slightly better. If you want to spend that kind of money for a HT amp and you like the Simaudio sound, you can't go wrong with the Titan.
Chris.
