How do records not skip on the Andover-One SB, even with a speaker underneath the turntable?

The Andover-One SB is purpose-built to prevent skipping—even with powerful speakers housed directly beneath the turntable. At the heart of its design is Andover’s patented IsoGroove™ technology, which isolates the turntable from internal vibrations that typically cause skipping or feedback. The platter sits on a floating platform mechanically decoupled from the speaker cabinet, using isolation grommets and dampers to ensure stable playback at any volume.

Additional vibration control comes from a dense MDF chassis with layered construction, internal bracing, and acoustic dampening. Side-firing subwoofers and a built-in DSP deliver deep, controlled bass while avoiding the low-frequency rumble that can disrupt playback.

How can the Andover-One SB outperform a traditional high-end component setup?

The Andover-One SB delivers true audiophile sound—without the complexity, clutter, or cost of a multi-component system. Instead of piecing together amps, speakers, cartridges, and cables, you get a fully integrated system that’s expertly tuned and ready to perform in any room.

Inside, you’ll find premium components: dual direct-drive amps for clean signal flow, AMT tweeters for crisp highs, and four high-excursion woofers for tight bass and accurate playback. The built-in phono preamp and speaker amps are perfectly matched in-house, giving you high-end performance without the guesswork.

Is the Andover-One SB easy to set up?

Absolutely. Just plug in your turntable using the phono input (with built-in preamp) or the line-in, depending on your setup. No extra gear. No messy wiring. Just pure, great sound—right out of the box.
