Trans Fi Salvation direct rim drive turntable


Hi A'goners, I've just bought this turntable, confident it'll be my last upgrade. The rest of my system is a Tom Evans Groove Plus SRX phono stage, EMM Labs CDSA SE cd player, Hovland HP200 pre/Radia power amps, Zu Definitions Mk 4 loudspeakers, so a pretty good way to listen to vinyl.

Over the years, since 1995 I've progressed from a Roksan Xerxes/Artemiz/Shiraz, via a Michell Orbe/SME V/Transfiguration Orpheus, finally ending up last week with my new Trans Fi Salvation/Trans Fi T3Pro Terminator/Zu modded Denon 103.

This turntable (£2500 UK price, approx $4000-$5000 US) is the brainchild of Vic, a retired dentist, who, fed up with the shortcomings of belt drive and traditionally-pivoted tone arms, literally from the ground up devised first the Terminator air bearing linear tracking tone arm (now in T3Pro guise as on my system), and now the direct rim drive Salvation turntable, a technology in direct opposition to the hegemony of belt drive we've come to accept from the '70s.

In summary, he has developed a motor that directly rim drives an oversize platter. The magic is that vibrations are drained away from the platter and hence stylus. So minimal rumble is transmitted, the weakness of Garrards/Lencos in the past. This is mated to a substantial slate plinth which does a great job of isolating the whole rig from external vibrations.

Where this differs from direct drive is that the torque applied is high enough to counteract stylus drag, but it is strictly analogue controlled ie no digital feedback applying constant micro speed control. Speed is set correctly, torque is sufficient, and speed stability is like a rock.

This is combined with his air bearing linear tracking arm, discussed on other threads.

So technical description over, how about how it sounds? Well, years ago I always assumed the overhang in bass when playing lps on my previous belt drive/pivoted arm tts, apparent as a benign artifact, was all part of the 'romance' of vinyl, esp. when compared to the dry, clinical sound of early cd. But in 2007 I acquired the EMM cd, which had a natural analogue sound playing silver discs, but none of this bass colouration. On studying the growing reemergence of idler/direct drive, and their superiority in maintaining speed stability, I agreed that the belt speed instability might be introducing this.

Two years ago I came across Vic, and now I can report that eliminating the belt for high torque rim drive has taken this whole artifact out of the equation. Whole layers of previously masked information like rhythm guitars are now present, treble information has abundant naturalness and decay, and bass, which appears to be less in quantity compared to belt, is actually more accurate with a real start-stop quality, much more like digital, and the real thing. The other positives are more linked to the arm, including uncanny tracking across the whole record side; I'm really not exaggerating in saying that the last few grooves at the end of an lp side are as solidly reproduced as the first. Music with strong dynamic contrasts are really served well by the Salvation, and I am shocked at how good this all is after trepidation that the sound might be hyperdetailed but too assertive etc. In fact music is reproduced with a relaxed incision, and a welcoming detailed transparency.

The amazing thing is that all of this is not in anyway at the expense of the natural warmth and tonal dimensionality that still puts vinyl way ahead of any digital (imho).

The only thing, and Vic would like this to be known, is that his creation is a cottage industry, and he can only produce limited numbers to order.

I'm happy to answer qs on it, as I really want our community to know about a possible world beating product at real world prices. My tech knowledge will be limited, but no problem discussing sound quality issues.

I'm not affiliated in anyway to the product, just sold my Orbe on ebay and bought this. Regards to all

I have the Trans-Fi arm and the Reso Mat. Both are keepers. The arm is superlative. The mat benefits from light clamping, at least on my modified VPI TNT.
Spiritofmusic, I'm a slow learner. My modified TNT is all that it can be, easily surpassing the current HRX that I've heard at shows. The Terminator arm with Reso Mat, both before and after modifications, is so good that I'm inclined to trust Vic a priori. Thanks for your review. Based on input from those I know & trust, my next step is either a refurbished Kenwood L07D or Salvation.
Sgunther, The short Tomahawk wand is too light for low-compliance cartridges like Shilabe. For those types I machined a heavier rear counterweight and several types of front counterweights that drop into the holes of the Tomahawk wand or slide along its flat surface. In addition, Vic has a special pivot that can be set up to support adjustable front and rear counterweights on a threaded shaft. Do something like this and the arm will work optimally with any cartridge.
Dover, to suggest that the Trans-Fi arm "is not a very good design at all" due to possible bearing wobble ignores a complex of variables.

Unlike any captured air bearing design, this is a mechanical pivot arm in the vertical plane and an air bearing in the horizontal plane. As all air bearings move freely in the horizontal, the possibility of wobble is relevant only in the vertical plane. The vertical needle pivot points hang in a cradle well below the air bearing. (The two needle pivots are also spaced apart by a generous 2.5" for stability.) It would be complex math to model this system precisely, however it is easy to see that the system is relatively stable, as by definition the mechanical pivot is absorbing most of the vertical dynamics of the arm. (Picture a see-saw that pivots on the seat of a swing. Will the action of the see saw move the swing?)

The stability of the air bearing itself is a function of a several factors: the surface area of the bearing(a generous 14 sq. in.), the length of the sled(a generous 7"x 2" "air foil" that rides like an airplane wing (an airplane wing of sufficient size for its fusilage and cargo becomes stable, No?)

There are also other variables operating on the comparison bewteen these arms: short arm vs. long arm resonance characteristics, lighter vs. heavier vertical inertial mass characteristics, low vs. high air pressure turbulence/pulsing characteristics transmitted to the stylus.

The complex of variables in each these arm should be considered in totality. As in all things audio, it's disingenuous to generalize.

Lewn, BTW there is not moisture issue with this arm since there is no compressor tank. The bearing operates at the same 1 psi output as produced by the aquarium pump.
If an accident happens while loading an LP, it will likely be a scratch against the lowest point-- the steel tip of the long cue bar. A good precaution is to slip a bit of soft plastic heat-shrink or rubber hose over the cue bar tip.

BTW, anyone shy about an air bearing tonearm may fear that an interruption of the air supply will cause the stylus to stick destructively in the goove. This is not a problem with Terminator. In this event the vertical point bearing continues to function, causing a light skip without damage.
I use a light clamping force, with rubber washers of correct thickness underneath and on top of the Reso-Mat as required to cup the LP onto to the vinyl acetate cones of Reso-Mat without excessive compression.
The coupling points used on Resomat complicate the discussion. There are six vinyl acetate points at the lead-in grooves and three in the run-out section. Points are generally accepted as viable in other contexts of audio, so why not for an LP?

Wherever I have used points I find that mass loading improves things. My experience of Reso-Mat without clamping was similar to TheKong's. I heard an improvement in clarity at the cost of paleness or a slight loss of embodiment. In addition, while Vic believes that the unweighted record doesn't slip against the points, I'm not so sure. The points have a light grip on the LP relative to a flat mat or platter surface. Unfortunately I have no fancy tools like Timeline to quantify any effect on transient speed stablity.

Adding a light clamping force improves embodiment, levels the LP, and adds a reassuring bit of grip. Excessive clamping sucks the life out of it.
Dover, taken with a small dose of Lithium, that should get you through the night.
Redglobe, I would imagine that Vic could make a 1-2" longer Terminator air manifold for use with the GEM's outboard arm pod or to increase clearance between the arm wand and a periphery ring.
Spirit, I am not so surprised by the general lack of interest expressed in the "Trans-Fi approach." The marketing for Salvation, limited as it is to word-of-mouth, is co-joined with marketing of Terminator arm. I'm hoping that the appeal of Salvation will someday be broadened with an offering of multiple arm mounting points. This would encourage owners of pivot arms to give Salvation a try and to compare their darlings of the pivot world to Terminator. The linear Terminator is a tiny sliver of a small subset of the total market for tonearms. Modern linear tonearms are largely unappreciated and misunderstood, Terminator particularly so. When I think about this design, the only disadvantage I can think of(based entirely on conjecture, not on practice IME with Terminator)is the possibility that the sled bearing may become unstable and rock front to back with forces operating on stylus. To this point I recently learned of an experiment with a laser pointer that refutes this criticism. A mirror was afixed along the sled's 90D perimeter to reflect the laser beam from the horizontal onto a high ceiling. The laser dot stayed motionless on the ceiling throughout play. The geometry and resolution of the experiment suggests rocking of 2um or less. Terminator appears to be the only linear tonearm with good bearing stability that operates at very low air pressure. High pressure may cause bearing chatter and vibration at stylus. Once you get over the hump of good bearing design, most of the caveats about a linear design are minimized.

I'm curious if ttweights had experience with any tonearm on L-07D other than the stock Kenwood TA-07J unipivot. IME the Trans-Fi Terminator sounds superb on the L-07D, and may be a spoiler in comparing the L-07D to the rim-drive tables.
On Kenwood L07D and VPI TNT I've tried a DIY 4 lb. brass weight and a 1 lb. 6 oz. Stillpoints LPI on top of Resomat. The LPI has just enough weight to couple the full circumference of the LP to the Resomat points-- increasing foundation without strangling "breathe."
