U-Turn Audio Orbit Theory: A Turntable 10 Years In The Making

The little engine that could tucked away in a suburb outdoors of Boston is pretty much 10 a long time old and it is difficult not to be impressed by what Ben Carter and the individuals at U-Flip Audio have achieved. The new U-Change Audio Orbit Idea Turntable is a large milestone for the enterprise that has centered on the market place under $400 for most of their existence.

When I visited the corporation pretty much 7 many years back, it was unachievable not to see that they were battling with the sheer quantity of orders and that they essential to discover better domestic sources for their platters, plinths, and motors. Carter and I talked about the rationale for the price structure of their tables and the possibility of production something in the $700 USD array.

There was by now the drive to make a thing like the Orbit Theory and consider on Rega and Professional-Ject, but that necessary a lot more funds, employees, and the capacity to generate a tonearm that would be a big enhance in excess of the tonearm on the present Orbit.

U-Turn Audio Theory Turntable Walnut Angle

The new U-Flip Audio Orbit Concept is $999.95 USD — you can also purchase a edition with their inner phono stage for $1,069.95.

U-Flip also made the decision to promote the Orbit Principle with an Ortofon 2M Blue MM Cartridge pre-mounted the 2M Blue retails for over $239 producing the Orbit Idea an exceptional price under $1,000.

Getting offered very well more than 100,000 turntables all over the time that the pandemic arrived, the business centered on having orders transported faster, securing a a lot more secure supply of cartridges because the demand from customers for cartridges was exceeding provide, and planning for the potential.

What’s also appealing about the U-Transform Audio Orbit Principle is that cost puts it into direct opposition with the Professional-Ject Debut Professional and Rega Planar 3.

Style and design Philosophy

The U-Change Audio Orbit Theory began as an experimental test bed for new thoughts and models. It was an opportunity for the crew to thrust turntable performance to the up coming stage devoid of constraints, with no any certain price tag point in mind, but also with the knowing that their consumer base was not going to all of a sudden spring for a $3,000 turntable.

The aim with the new Orbit Concept is clearly on the tonearm, motor, and design of the plinth.

OA3 Professional with Magnesium Armtube

It was essential to Carter that they designed and assembled the new tonearms in-dwelling.

For the Principle Orbit turntable, U-Convert made the decision that they necessary to consider their OA2 gimbal bearing structure to the following level by further minimizing factors of resonance in the tonearm. Nearly talking, this meant using extra rigid materials and reducing the quantity of link points involving areas.

To do that, they built an arm tube that combines the headshell, tube, and pivot housing into a single, continuous piece. This structure leaves no link factors for resonances to creep in involving the headshell and tonearm pivot. But what substance would this be built of?

When we saw the to start with illustrations or photos of the tonearm, we puzzled if an additional American turntable manufacturer had created a 3D printed variation for U-Turn but the price of creation seemed out of whack for a $1,000 turntable. I have individual working experience with how that arm was developed and manufactured and it did not appear like a chance when I commenced doing the math in my head

Ben Carter desired anything mild adequate to protect the very low powerful mass of the arm tube nevertheless solid plenty of to not resonate through playback.

The response was magnesium. Not only does magnesium have an remarkable strength-to-fat ratio, but it can also be molded into complex styles using a procedure termed “thixoforming.”

This approach designed it possible to combine the unique tonearm factors into a one piece, preserving the arm’s effective mass and very low heart of gravity. 

The tapered arm tube style keeps vibration away from the stylus and assures the partitions of the arm tube are as slim as doable, keeping mass minimal. U-Flip greater the successful duration to 7mm for reduce angular monitoring error and considerably less distortion. 

The OA3 Professional didn’t occur right away. The company worked carefully with their Wisconsin-based magnesium molder for around a year to establish and establish the intricate device necessary to manufacture the arm tube. The end result is an extremely sturdy, very low resonance arm tube created in the United states.

U-Turn Audio Theory Walnut Turntable Pulley

All new push program

Just about every aspect of Orbit’s drive program has been revamped like the motor my largest complaint in 2015, and in 2019 when I obtained an Orbit+ for my daughter was the motor noise and the free in good shape of the pulley.

The new motor and pulley are so peaceful that they can be mounted right to the plinth, guaranteeing best belt alignment. The motor is electronically managed by a DC-driven sine wave generator – this gives very stable platter pace and gives you the capacity to modify between 33/45 RPM with the change of a knob.

Theory’s acrylic platter is frosted, and all of platter surfaces have been precision machined for maximal flatness and nominal runout. They have also machined a groove into the platter to keep the belt in place.

The Orbit Theory’s belt is a new seamless style and design that is molded from silicone. It is more long lasting and won’t extend in excess of time — a person of my greatest frustrations with the Orbit+ that I bought for my daughter was how conveniently the belt fell off the platter or twisted during operation. The new style and design is a large enhancement in that regard.

U-Turn Audio Theory Turntable Top

Ebonized Oak

What far better way to rejoice a new turntable than with a new complete? For Principle, U-Convert determined to do authentic hardwood plinths, but required to spice matters up a bit. Ebonization is a conventional finishing approach that turns wooden black without the need of staining or painting.

Ad. Scroll to keep on looking through.

The coloration improve is introduced on by a chemical reaction among iron oxide and the pure tannins in the wood. Ebonization bodily turns the fibers of the wooden black – in contrast to a paint or stain that sits on prime of the wood. U-Turn worked intently with their local woodshop to ensure that the completed plinths presented a substantially larger degree of finish than even their Orbit+ hardwood designs.


The U-Flip Audio Orbit Principle is obtainable now for $999 at uturnaudio.com.
