The Audio Analysis I/50 Built-in Amplifier is on the market in 6 colours with non-obligatory DAC and Phono modules, which is how the overview pattern is outfitted and wearing Gold, providing 50Watts of output energy from 2 pair of JJ 6550WE vacuum tubes.
The Phono module gives 42 dB of acquire making it appropriate with transferring magnet and high-output transferring coil cartridges, whereas the non-obligatory DAC module gives USB (helps PCM resolutions as much as 384kHz and DS128), Toslink, and Coax inputs in addition to Bluetooth for comfort. There’s a complete of three line stage inputs (2x RCA, 1x XLR) and speaker binding posts with 4 and eight Ohm faucets.
Becoming a member of the 2 matched pairs of JJ 8550s are three 6922s (1x enter, 2x driver) and for a enjoyable visible deal with a pair of AR’s LexieTubes that mild up with a begin up rely down and, as soon as heat, quantity stage and lively enter. A 1/4″ headphone jack additionally sits on the excessive gloss black high panel together with the facility button, quantity and enter choose knobs. A wafer skinny steel distant is included.
The I/50 is constructed at Audio Analysis’s Minnesota HQ and the aluminum high plate encompass has a Cerakote ceramic end that is available in Gold, Pure, Crimson, White, Black, and Blue. Coloration is nice.
Audio Analysis was based by William Zane Johnson in 1970 (!) and so they have constructed their justifiable share of basic gear together with the D150 amplifier (1975) and SP10/SP-10PS pre/energy combo (1982). The corporate was lately acquired and is operating easily so I’m particularly thrilled on the alternative to spend time with the I/50.
