VTL 6.5 Signature Preamp in operational condition, running nos telefunken tubes with a back up pair included. This is the original VTL TL-6.5 version.Please reference photos for cosmetic condition.Well reviewed in Stereophile by Larry Greenhill in 2007:The VTL TL-6.5 Signature performed brilliantly in my system, revealing dynamic contrasts both subtle and bold, holographic soundstaging, and solid, deep, tuneful bass. Its remote quickly controlled the TL-6.5 from any convenient listening position in my living room, and the preamps front-panel display is readable from 10 away. The TL-6.5s ergonomics are the best Ive encountered for a preamplifier.Complete balanced topology with multiple xlr inputs and output or rcas. Input volume balancing, home theatre pass through. VTL is a very solid company that will respond to questions. Many reviews, its a very well engineered unit. Includes remote, manual, original factory packaging.
