Personally we can't think there would be any reason why these two couldn't work together.
However in our opinion you can get better sound for less money than the Dagastino gear with the T+A electronics they make an extraordinary 300 watt per channel power amp which competes with the much more expensive Dag amp.
As per sonic flavors these are two totally different sounds, the Spectral is super clean and fast, the Dagastino is more traditionally a warmer more laid back sounding product.
If you like the sound of Spectral go with Spectral if you like Dag go with Dag gear.
Hope that helps.
