i recently updated my CB II to a III with an extreme DAC. I was planning on upgrading my speakers but find it no longer necessary. I use aerial acoustic 10T and CC5 and SW12. The sound is supurb. I had been planning on getting the 20T but frankly it doesn't seem necessary. The aerials are a perfect match for Theta. BTW, I have a Dread II as well and biamp the CC5. I went with monoblocks for the 10T. You can pick up 10T for a steal on agon.Good luck.ken
