Spectral recommends that its amps and preamps be utilized together. i agree with Audiotroy in that mixing Dag and Spectral will get you the worst of both worlds. Go all Dag or Dag amp with tube pre, a combo I have heard in my home which I thought was fabulous. Spectral is fast and clean. If you like that, go all Spectral. Anything else will ruin its presentation, not complement it.
D’Agostino amp with Spectral preamp
Is trying to run a D’Agostino amp with a Spectral totally not doable? The reason I ask is that I was thinking of adding the amp in my system first then getting the Dag preamp or a tube pre later. Later is much later like a year. Do you think this would sound terrible?
