IT-85 Integrated Amplifier

it85-featured

The VTL IT-85 Integrated Amplifier is designed for those who seek the simplicity of a single chassis system, but with the performance of separates. Designed with a fully active preamplifier stage, the IT-85 delivers a hearty 60 watts per channel with the sonic characteristic that is similar to our well regarded ST-85 Stereo amplifier and the TL2.5 preamplifier combination – fast, musical 3-D sound, and solid bass support that VTL is known for.

The IT-85 is a full linestage preamp and power amplifier in one chassis, and the linestage section has sufficient gain and a buffered output to be able to drive a subwoofer through the preamp out. The headphone section of the IT-85 is driven off the tube output stage and output transformer of the power amplifier section thus making it an ideal high performance pure tube headphone amplifier for headphone aficionados.

The IT-85 is designed to accommodate future upgrade — when you are ready to add a subwoofer, separate pre- or power amplifier, surround processor or headphones to your system, the IT-85’s many different output stage configurations can be easily and painlessly re-configured, often with just the flip of a switch. Hand built in our factory in California with the proven VTL quality, the IT-85 will give you lasting value and listening pleasure for years to come.

Vacuum Tube Logic IT-85 integrated amplifier

… it’s an amp that will grow with your listening. With a good front end and speakers appropriate with the IT-85, one of the big pluses is the imagery. The soundstage is open, wide and deep, with instruments neatly rooted in space. It scaled well too, not struggling when moving from uncomplicated girl-with-guitar music to full-tilt Pavarotti pumping out Turandot with those XXL lungs he had. But most of all is a sense of lucidity and insight that draws you in and keeps you there. Read the full review here…

Tubular Sells

…With a well recorded source, the VTL made me forget that I was listening to a hi-fi system at all. The music existed like a sonic projection. That’s what the VTL is capable of doing, becoming seemingly invisible. It is one of the most ‘realistic’ integrated amplifiers on the market I feel and highly recommended. Read the full review here…

Il piccolo di casa VTL

…The sound is typical of VTL: bass the envy of a solid state, fast transients, wider soundstage and deep musicality combined with rigor and beauty in tone… on the contrary there are no noticed colorations or rounding at the ends of range, but we have a very seductive tube sound and a very fine grain, almost velvetly feel… Read the full review here…

VTL IT-85

American company VTL is known by its tube amplifiers, but also by the concept that tubes can be user‐friendly. Here we have basic integrated amplifier named IT‐85. Very often, your audiophile friends, will advise you not to buy the first, basic model of any manufacturer. However, if the price range goes beyond the amount of 5.000 euro, then there is probably no reason to worry – you can be sure than nothing was second best… Read the full review here…

Diapason D’Or award – Amplification category

… displays a rigor, beauty and precision that most solid state amplifiers would turn pale in comparison … the richness and realism in the sound are rarely found in solid state amplifiers …three dimensional image, perfect timbre, large sound stage … the voice and instruments have a well-defined dimension … excellent definition and dynamic that is full of panache …
