I 'm considering the Wyred4Sound digital amps for my SongTowers but am not sure which model. I listen to jazz, guitar and piano solos, vocals in the line of Diana Krall and Rebecca Pidgeon, at moderate levels.
With my Parasound HCA2200MkII and P/LD 2000 (385W into 4ohms) I rarely go above the 10 o'clock setting on the preamp dial.
The ST250 is rated at 195W into 4ohms; the ST500 is rated at 550W into 4ohms. Since the SongTowers have an 80 - 200W SS amp recommendation, the ST250 seems to fit. The ST500 would have MEGA headroom. The ST250 is $500 less than the ST500, that's a lot of new CDs.
Your thoughts, insights, recommendations are much appreciated.
