VSi55 stereo integrated amplifier

VSi55 stereo integrated amplifier

"Exhibits an open and airy head, with the swift legs to keep up with dynamics and pace, and the biceps to keep heavy material from sinking. Its vision is perhaps not quite 20/20, as imagery falls short of completely pinpoint, but this is countered with an overall attitude that manages to be both unapologetic and satisfyingly warm."

The VSi60 clearly proves that you do not have to spend a fortune to enjoy truly great sound at home. Built by hand in Plymouth, Minnesota, to the same exacting standards as our renowned Reference series, the VSi60 offers remarkable sound quality and value. Its rated output of 50 watts per channel does not convey the VSi60's ability to drive power-hungry, low-impedance loudspeakers. We designed the VSi60 with the finest full-range speakers, not compact monitors. Dynamics are lifelike with a sense of ease normally associated with larger amplifiers. Yes, its resolving power is surprising, allowing you to hear details that were previously hidden in your recordings, but that resolution is in service of the music — grainless, tonally accurate and refined.

The LS17 SE preamplifier benefits from a long tradition of exceptional preamplifier technology from Audio Research and shares many common traits with its larger peers.

REF. 5 preamplifier

REF. 5 preamplifier

The REF5 is only the second Reference preamplifier to have its main board laid out horizontally, after the REF Phono2, with its transformers off the board and mounted on the sides of the chassis. The new audio circuit is fully balanced, pure Class-A triode, with zero feedback. The tube complement includes four 6H30s in the analog stage, with a 6550 and a 6H30 in the power supply. Massive energy storage, the most of any Reference preamplifier, provides tremendous dynamic capability. Total gain is 12dB via the balanced outputs and 6dB via the single-ended outputs.

DS225 stereo power amplifier
