Data Specification

TL5.5 Line Stage Preamplifier received an outstanding review in the November 2002 issue of Stereophile magazine by Chip Stern. Chip was taken back by the top-end extension and close-up detailing of the TL5.5 preamplifier. With its richly detailed, tonally accurate and nonfatiguing sound, Chip concludes that the TL5.5 is a fine example of the midrange liquidity and human character that a finely tuned, non-invasive tube design can add to any signal chain.
