Ortofon ST-70 Transformer

The Ortofon ST-70 reserved for the discerning audiophiles and music lovers. The ST-70 combines the fine components along with world-class engineering, for unparalleled sound reproduction.

Starting with high quality Lundahl™ transformers, surrounded by a specialized mu-metal shielding, listeners can be assured that every detail in a complex array of notes is reproduced with utter purity, with freedom from internal and external sources of interference. These two items combined make the ST-70 transformer one of the quietest, most revealing transformers.

Featuring dual mono design, the ST-70 provides discrete circuitry for each channel, resulting in the elimination of crosstalk and possible distortions.  This results in cleaner, clearer reproduction with substantially increased stereo imaging.  Regardless of the composition being played, the ST-70 expansive stereo separation provides lifelike realism, and accurate tonal balance devoid of coloration.

ST-70 configurations and technical data

Technical data Configuration A:
Recommended cartridge impedance 5-50 Ω

Dimensions: 58 mm(W) x 135 mm(H) x 150 mm(D)
Weight: 1.233 kg

    Terminal connections

    To further minimize signal degradation and maximize signal flow, the ST-70 has been engineered using high quality industrial grade PCB.  Additionally, gold plated RCA jacks with Teflon insulation provide optimal conductivity for use with high quality interconnects. Internally, the unit is assembled with an absolute bare minimum of internal wiring, preserving absolute signal integrity. 

    1. Output terminal for Right channel RCA plug
    2. Input terminal for Right channel RCA plug
    3. Grand earth terminal
    4. Output terminal for Left channel RCA plug
    5. Input terminal for Left channel RCA plug

     

    The ST-70 applications

    The ST-70 maintains compatibility with most Moving Coil cartridges by using internal jumpers to select between two gain/impedance options. This affords audiophiles with broad flexibility while still maintaining a clean aesthetic.
    The ST-70 transformer is a perfect partner for the Cadenza Series.

    Why use a transformer? Since the output of MC cartridges is low, higher gain is required to utilize it, such as that provided by Step-up moving coil transformers or MC phono preamplifiers. Although both devices provide this requirement, both are fundamentally different in function and in sonic character. This is where Step-up moving coil transformers are frequently seen as superior; they are completely passive and offer exceptional noise performance and sound quality.

    Comfort + Style = Dream Walkers
    Size: 13, Color: Dark Black
    Im in awe of how comfortable these are. Took a chance on this unfamiliar brand because the price and style were just what I was looking for. They came today tried them on, they are so light and airy and the super spongey soul make them dreamy to walk on. Now let's just hope they last 🤞🏼 Thanks for making a great shoe!

    Stylish Look and Comfortable for Daily Wear
    Size: 9, Color: Navy Blue
    I bought the SVNKE men’s fashion dress shoes mainly for casual office wear, and they’ve been a pleasant surprise. The design looks sharp and gives a nice mix between dress shoes and sneakers, so they work well with both business and casual outfits. They are surprisingly comfortable right out of the box. The cushioning is decent, and I’ve been able to wear them for most of the day without discomfort. They also feel lightweight, which makes them easy to walk in. The build quality is okay for the price—not premium, but solid enough for regular use. Overall, these are a great budget-friendly option if you want a versatile shoe that looks good and feels comfortable for everyday wear.

    Better quality than the others!
    Size: 10.5, Color: Dark Black, Size: 10.5, Color: Dark Black
    I’ve had a pair of these in grey for over a year and was looking for black shoes to replace my worn out old ones, so I decided to give these a try. Just like the grey, these did not disappoint. They have a different/look design than the standard breeze/cole haan knockoffs you see everywhere. They look and feel a lot better. The insoles have more support and the outer sole is very cushioned, making them comfortable all day. With the other knockoffs, I usually buy an additional insole for support since they come with a laughable sponge laid in the shoe, which is an added expense. This alone makes the SVNKE a great option. If you like the different look of these, then definitely get them, you will appreciate the higher quality!

    Fantastic purchase
    Size: 12.5, Color: Black
    Fantastic purchase. I had a trip to Spain planned and wanted shoes that would work both for lots of walking and also more dressy events so I bought these. After a nine day trip to Spain, walking over 20,000 steps a day through cobble stone streets I can report these shoes held up, were comfortable, gave no blisters, and all with virtually no break in time for the shoes. I wear a size 12 but bought a half size larger and it was a perfect fit. Definitely recommend these.
