Theta Dreadnaught vs. Simaudio Titan

They are both very good - the Dreadnaught has more smoothness, or perhaps you can call it a darker, less detailed sound. I believe with difficult speakers, or any speaker that can play loud and clean and very deep, nothing beats a Titan. It's a beast of an amp.

Thank you, Audio4ever. I ended up with Dreadnaught II, and I really like it. Never had a chance to hear Titan though.
