I recently purchased the Wolcott mono's to power my Inner Sound Eros. The Eros are a ESL hybrid with a nominal impedance of 4 ohms. The Wolcott's produce the best bass I've ever heard from the Eros. More tuneful and accurate than the bass control of my Classe CA-300. These amps are also just superb in the midrange and top end probably due to the generous banks of EL34 tubes. Far better sound and control on the ESL's than the Rowland gear I've used. Soundstage is higher and significantly deeper. The real story behind these amps is how tonally correct they are. From what I understand from Wolcott dealers they are an exceptionally good match with Sound Lab speakers. You owe it to yourself to audition a pair. Best amps I've ever heard. However, it's hard for me to think you'd go wrong with either the VTL or Wolcott. Regards; -Jerie
