Audio Research I/50 Integrated Amplifier

The Audio Research I/50 Integrated Amplifier is your gateway to sonic nirvana, a sonic sculptor that breathes life into every note. It's not just about specs and features; it's about an experience. Simple to use, drop-dead gorgeous, and packing a serious musical punch, the I/50 elevates your listening sessions from background noise to full-on audio adventure.

Hand-Crafted Magic Made in the USA

These aren't your mass-produced amps. Every I/50 is lovingly built by audiophile artisans right here in Minnesota. And get this – each one gets a personal audition by the legendary Warren Gehl himself, so you know it's going to sound incredible right out of the box.

Feast for the Eyes, Symphony for the Ears

The I/50 isn't just about the sound (although buckle up, because that's mind-blowing). It's a looker too. Wrapped in your choice of six stunning Cerakote® finishes, it becomes a statement piece in any listening space. These finishes are tough as nails and easy on the eyes, so you can crank up the volume without worrying about chipping the paint (although your neighbors might have something to say about that).

Simplicity that Rocks (Literally)

Don't let the user-friendly design fool you. This amp packs a serious sonic wallop. 50 watts per channel of pure, unadulterated tube power effortlessly drives a wide range of speakers. Forget wimpy digital amps – the I/50 delivers rich, warm sound that gets you right in the feels, whether you're rocking out to your favorite classics or getting lost in the delicate whispers of a jazz ballad.

An Amp that Grows with You

Think the I/50 is a one-trick pony? Think again! This modular marvel lets you add a phono stage and a D/A converter to create a truly all-in-one audio solution. Build your dream system piece by piece, all while maintaining the incredible sound quality that Audio Research is famous for.

Warm Analog Goodness for Your Ears

Those two high-performance 6550WE tubes and three 6922 tubes aren't just for show. They're the secret sauce that delivers the rich, detailed sound that only true tube amps can produce. Rediscover the magic of your favorite music with unparalleled clarity and warmth – it's like hearing your favorite albums for the very first time.
