I spoke with Kara Chafee, the designer of the Verve preamplifier, about the synergy of their preamplifier with digital amplifiers. She stated she had customers with digital amplifiers that are astonished about how well her preamps work with digital amplifiers. She e-mailed me the e-mails they received from a customer who has a Spectron III amplifier. This customer could not believe the sound he was getting using the Verve with the Spectron. Kara explained that the Verve projects a huge 3D soundstage that is so real its spooky. She said the the sound of the Verve is not Classic tube. The Verve is quick and dynamic like a solid state with bass that's on par with the best solid state preamplifiers. Yet the Verve has a airy and natural presense that expands the soundstage like tubes. She concluded by saying the Verve is built like a power amplifier and that expalins its unigue abilities. Dick Olser at enjoythemusic.com has posted a review on the UltraVerve preamplifier. Well, when I get my Carver ZR-1600 back from Steve at Empirical Audio you better believe I'm going to addition this preamp with it.
