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

Redglobe, I'm not sure there is an article that compares the Salvation to Ttweights. One thing I can say is that although the two designs are similar ie direct rim drive, Vic the designer of the Salvation assures me his motor is very different ( I assume superior?) to that of the Ttweights.
I do know Vic investigated the Teres Verus and in the end scrapped the idea of using it, preferring to build one up from scratch.
Vic's main advantage is being able to provide very stable, very high torque to the massive oversized platter (it is next to impossible to slow the platter manually without using lots of pressure, v. different from my low torque belt drive), at the same time effectively draining the vast majority of vibrations away from the platter hence minimising rumble.
The day to day result of this is only occasional need to tinker with speed settings, never mid lp, and a soundstage so open and transparent that no subjective evidence of rumble is present.
I still contend the tt/arm combination is the biggest bargain in the high end today.
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.
Dgarretson, I have to agree with you. I can't add to your technical analysis, but this arm is a MARVEL of tracking and neutrality.
Before buying it, I was really unsure about the maintenance issues of using an air bearing linear tracking arm. It's only downside is a real need for perfect level, freedom of air supply (reas. easy to achieve), and isolation from vibration (a little more tricky, I'm having to resort to a wall shelf to eliminate floor borne disturbances).
However it's upsides are really decisive. Dominant amongst these is unbelievable tracking esp. towards end of side/lead out grooves: I can honestly say that there is a real stability of sound reminiscent of the best of digital, that means cart tracking toward the end of lp play is as good as when the stylus hits the grooves as an lp side starts to play.
I personally can't understand why anyone would get involved with this turntable. With the likes of VPI, Sota, SME, etc. who will solidly support the owner with a business that is a proven going concern and who will be there for their customers 3 years from now I can't see the benefit of this proposition.
Stringreen, I understand your reservations re Trans Fi being a small name with no substantial reputation like the names you have mentioned. This is very true, although Vic has been making his arm for several years now, and this has proved to be reliable and extremely good VFM. The Salvation has been selling for over a year now and is developing a similarly positive reputation. Additionally, it is a cottage industry, Vic can only build to order, and indeed he wouldn't be able to cope with a mountain of orders.
One thing that VPI, Sota, SME etc. won't be able to provide is a paradigm busting approach to getting the best out of analogue, technology that emphasises all it's positive attributes with few of the negatives associated with more traditional technologies that these established companies are limited to offering.
But you pays your money and you takes your chances...I did, and haven't looked back.
