D’Agostino amp with Spectral preamp

How can you tell if there is an impedance miss match?

What's the output impedance for the preamp and the input impedance for the power amp?  I could look it up, but so could you.

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.

Pre-2k ohms,  amp 100k ohms

How do you know if that is a match or not
