I owned the 3a sigs and then bought the Treo non-CT's.
There is a definite improvement in sound quality when you move to the newer models. Plus, they also look nicer.
If I recall correctly, you own an Atma M-60.
The Treo's are rated 40wpc at the low end, so you should be good to go.
Especially if you add a Vandy sub or two- which will relieve the amp from all the heavy bass energy.
