Upgrade question

I currently have a Theta dreadnaught 11. I was looking to upgrade to a parasound halo a21 for two channel music. Would this be an upgrade from the theta amp. It would also match my Parasound c2. I am short on room for mono's. And the price seems right for the A21 thanks
No it wouldn't be an upgrade from your Theta. It would be a downgrade.
I'll second Mtdking's post.
I will third that !!
