ACCUSTIC ARTS® TUBE PREAMP V – Audiophile fully balanced reference preamplifier
TUBE PREAMP V highlights
- Audiophile reference preamplifier with a so called “tube hybrid” concept and 4 reference tubes (2 tubes per channel)
- Fully balanced circuit design from input to output
- Further optimized sound quality by new designed main board
- Advantages of this “tube hybrid” technology:
– very high bandwidth
– very low distortion factors and a “good-natured” distortion spectrum
– “analog” and very precise sound performance
– 4 separated amplification paths, which are not influencing each other - Easy change of tubes without any adjustments just “plug and play”
- Fully balanced circuit design from input to output
- High end Class A output stage
- New with color high resolution display
- All used components are of outstanding quality (e.g. Burr Brown® OPA 627) and additionally selected; all relays have high quality gold-plated contacts
- New 4-channel digital volume control for best crosstalk
- All relays have high quality gold-plated contacts
- 3 x fully balanced high level inputs (XLR) and 2 x unbalanced high level inputs (RCA)
- 1 x unbalanced input (RCA) configured as “SURROUND-BYPASS”
- 2 x fully balanced outputs (XLR) – 1 x AC coupled, 1 x DC coupled
- 2 x unbalanced outputs (RCA) – 1 x AC coupled, 1 x DC coupled
- 1 x headphone output, switchable (1/4″ stereo female jack)
- 2 x unregulated, switchable output for the connection of an external headphone amplifier (1 x RCA/ Chinch), 1 x (XLR) Phase switch for 0° and 180°
- 2 magnetically shielded, encapsulated 50 VA toroidal core transformer („Made in Germany“) of premium quality for high output reserves
- Front panel, cover are made of massive and solid aluminium; turning knobs are made of massive and chromed brass
- ACCUSTIC ARTS® TUBE PREAMP V is “Handmade in Germany”
