Personal speaking, I would just go for it [provided you have the money to spare (of course)]. I was looking to spend $2k on my mains, and searching very hard for them with nothing but compromise to be seen and heard. Then I heard the HT3 (HT2-TL wasn't out yet) and That was it. They did exactly what I wanted my mains to do. I couldn't settle for anything less at that point, and placed my order very soon after that audition. If the HT2-TL had been an option, I might have gone that route instead and been very happy (I still haven't heard them, yet). Do I regret going HT3? Not in the least, and I haven't even considered swapping them out or replacing them with ANYTHING since then.... well, at least until I heard about the SS8s!
I knew of the original SoundScapes and even got a chance to hear a pair, but they were way out of my price range, so it was very easy to write them off. But, Jim and Dennis just had to go and keep improving on things and produce the SoundScape8
The more moderate pricing, and better efficiency really seems to make the HT3 obsolete. Especially considering that the HT2-TL goes almost as low as they do for a good amount less money. As the line-up stands right now, I think the HT3 is for the guy who has his heart set on a three way design, and wants to run without a sub, and still cannot afford the SS8. With a sub, I think the HT2-TL is the way to go, and save a good chunk of money. No sub, a little $$$ to burn, and no worries about "could have," "would have," "should have,"
SS8. life is short enjoy what you can.
Cheers
