Review summary
Whether you listen to Rush Limbaugh, Howard Stern, or the local NPR outlet, you're probably going to love the Cambridge SoundWorks Radio 730. It's far and away the best table radio we've ever heard, and we've tried all the serious contenders. Its only notable shortcoming is the lack of a CD player; for that, you'll need to shell out an extra $100 for the Radio CD 740 model.

Cambridge SoundWorks Radio 730

THE GOOD

High-end table-radio performance; built-in powered woofer; excellent AM and FM reception; large 32-character display; slim remote; liberal connectivity options; 45-day home trial.

THE BAD

No built-in CD player.

THE BOTTOM LINE

Cambridge's feature-studded table radio delivers high-end sound.
The Cambridge SoundWorks Radio 730 makes a wholly positive first impression, and our respect only grew as we became better acquainted with its intuitive design. The 730 measures 14 inches wide, 5 inches high, and 10 inches deep; it weighs 11 pounds and feels like a substantial piece of equipment. It's available in black or ivory.
The 730 is a 2.1-stereo radio, meaning it features a pair of good-quality stereo speakers, a separate woofer (the .1), and three amplifier channels. Most of the 730's interior is reserved for the woofer and its associated vent system. That's how this little radio develops its room-filling sound. For just a radio, the 730 has an impressive feature set. Programming the stations and the dual wake-up settings was blessedly easy. You can opt to awaken to the radio or a beep, preselect the volume, and set the snooze interval from 5 to 55 minutes. The cute little credit-card-style remote isn't crowded with a lot of useless buttons.
We normally wouldn't have much to say about a table radio's connectivity, but the 730 is surprisingly well endowed. The AM and FM antenna inputs accept jacks instead of more difficult and fussy bare-wire leads. There are three 3.5mm stereo minijack inputs--a front-mounted one that's great for quick hookups, and two rear-mounted ones for more-permanent connections. One of the two rear inputs also serves as a "mixing" input: it can enable you to mix blips from your computer with the radio's sound, or it can output to a recording device, such as a CD burner. A headphone jack is also on the front panel.
The Stereo selector gives you a choice of Stereo, Mono, and Wide, which we really liked because it opened up the sound. Furthermore, the 730's bass, treble, and loudness controls let you fine-tune the tonal balance. We performed a brief comparison test with the 730 and a well-known table-radio competitor, and the 730's more full-bodied sound was superior. Additionally, we were able to crank up the 730's bass surprisingly far before we detected any buzzes or rattles.
For our listening sessions, we hooked up a new 15GB iPod to the 730's front input. We started with pianist Glenn Gould's Bach: The Goldberg Variations, worked a few Miles Davis sides, and topped it all off with Led Zeppelin II. The 730 took them all in stride.
The 730's FM reception was excellent even before we plugged in the supplied short-wire antenna, and adding it snagged low-power college stations. We also found AM reception to be above average.
Cambridge sells the 730 direct with an in-home, 45-day trial period, so you can check it out for yourself. It has a retail price of $249.

Out of stock

There’s something undeniably magnetic about vintage audio gear. The tactile weight of milled aluminum knobs, the warm glow of dial lamps, and—above all—the rich, analog sound that today’s sterile streaming boxes can’t quite replicate. But time is merciless: capacitors dry out, switches oxidize, and those gorgeous walnut cabinets lose their sheen. That’s where the art (and science) of our vintage audio refurbishment comes in.

Why Vintage Audio Still Matters

In the golden era of hi-fi—roughly the mid-1960s through the early 1980s—companies like Marantz, McIntosh, Pioneer, Sansui, and Technics were engaged in an arms race of build quality. This was before cost-cutting plastics and disposable designs; amplifiers were over-engineered, receivers were works of art, and turntables were precision instruments.

Owning one wasn’t just about sound; it was about status and permanence. These machines were built to last a lifetime—or two. The irony? Decades later, they often do, provided they’re given the care they deserve.

The Philosophy of Refurbishment

Refurbishment is not just about fixing; it’s about preserving authenticity while ensuring reliability. The goal is to keep that lush, analog character alive without compromising safety or sound quality.

Some enthusiasts chase museum-level originality—keeping every factory component in place. Others opt for sympathetic modernization, upgrading parts that never existed in the ’70s to improve performance. Both approaches can be valid; it depends on your vision.

The Turntable Store refurbishing process.. step by step

Step 1: The Initial Encounter

When we first meet a 40-year-old amplifier, we resist the urge to plug it in right away. That dusty Marantz 2270 might look gorgeous, but old electrolytics and brittle insulation can short instantly under full voltage.

Instead:

  • We inspect for corrosion, burnt resistors, and leaking capacitors.
  • We use a Variac (variable transformer) to bring up voltage slowly, reforming capacitors rather than shocking them back to life.
  • We check fuses—not just for continuity but for correct ratings.

Tip: A faint musty smell? That’s often the scent of old phenolic boards, not trouble. But a burnt smell? That’s trouble.


Step 2: Deep Cleaning & Control Detox

Dust is the enemy of good sound, that is why we clean the interior carefully with compressed air and a soft brush.

The real magic comes with switches and potentiometers. Over decades, oxidation builds up, causing scratchy controls and dropouts. A deep contact clean in each pot and switch, followed by vigorous cycling, often restores silky-smooth operation.

Step 3: Electrical Resurrection

This is where science meets art:

  • Capacitors: Electrolytic caps often need some attention. We replace out-of-spec caps with high-quality modern equivalents (Nichicon, Panasonic), avoiding over-capacitance unless the power supply can handle it.
  • Resistors: Carbon comp resistors drift over decades. Measure and replace out-of-spec parts.
  • Transistors: Certain vintage transistors (e.g., 2SC458) are notorious for noise. We do swap defective ones for modern low-noise equivalents.
  • Relays & Lamps: Speaker relays oxidize; replace or clean contacts. Dial lamps? Upgrade to warm LEDs for a factory glow without the heat.


Step 4: Cosmetic Glory

Refinishing the walnut cabinet can transform a unit. We do use real wood oil or Danish oil, not polyurethane. We clean the glass dial carefully; those silkscreened letters are fragile.

Knobs? We polish with metal cleaner, but never use abrasives on anodized aluminum.

Faceplate lettering? We avoid harsh chemicals—just mild soap and a microfiber cloth.


Step 5: Calibration & Sonic Check

After the repair and cleaning, it’s time to dial in the performance:

  • We do adjust bias and DC offset on amplifiers for stable operation.
  • On turntables, we re-lube bearings, replace belts, and check speed accuracy.
  • On Cassette Decks and Reel to Reels, we replace belts ( if needed ), we clean and demagnetize the heads before the alignment process ( a must ! ) 

When done right, the result is astonishing: a sound that breathes—liquid mids, velvet highs, and bass with a tactile presence that modern gear rarely matches.


Our promise for Audiophile-Level Results

  • We Avoid Cheap Parts: That $5 eBay capacitor kit? Hard pass. We use reputable brands.
  • We Don’t Over-Polish: Patina is part of the charm. We aim for “well-loved,” not “plastic surgery.”
  • We Upgrade Discreetly: If we must modernize (like adding gold-plated RCA jacks), we keep it tasteful and reversible.


Why It’s Worth It

The payoff isn’t just sonic—it’s emotional. Restoring a 1970s Marantz or Sansui is like bringing a classic car back to life. Every glowing dial lamp, every smooth rotation of a volume knob, connects you to an era when music mattered enough to build machines like this.

And when you drop the needle on your favorite record and hear that warm, enveloping sound, you’ll know: this wasn’t just a repair. It was a resurrection.
