FIDELITY RESEARCH STEP-UP TRANSFORMERS


Dear All
Like many before me I am moving down the multi tonearm route. Amongst the arms and cartridges I have are a Fidelity Research FR 64S and denon DL103. I was thinking about trying out one of the Fidelity research step-up transformers - preferably an FRT 4, or FRT 5 - I hope to get an FR7 cartridge at some point.

I was wondering if someone could:
1. shed light on the hierarchy of the transformers ie was the 4 or 5 the better model
2. would they work well plugged into any MM phono stage
3. what is the general hierarchy of the step-ups
4. Do they work well with modern cartridges - ie my shelter 501, transfiguration temper v, Benz LPS

I am hoping that someone will be able to help me

thanks

Dear all
Can i first of all say thank you for your responses - very informative so far.
As it happens i have 2 phono stages. A Vendetta SCP2B which I intend to use with a Transfiguration Temper V directly - I wish it had more inputs - hey ho.
My other stage is Whest 0.20 which can take MC or MM - with the Step Up i will put it onto MM.

I was curious as to what mods you carried out @rauliruegas to the denon.

I would ideally like at least 2 inputs for the step up. That is partly why i like the FR range. 

I was not familiar with the XG range - i note that there are no 7's for sale


@rauliruegas 
I hear what you say, but on the other hand many say the FR7f including the likes of @jcarr have commended it's unique design. Frankly - life's too short to not try one out. It's part of the reason that I am going to have a couple of multi-arm turntables.

That said how did you modify the Denon SUT? out of interest was it more transparent the other SUT's you used?

@rauliruegas 
I am somewhat surprised you don't know that the Transfiguration Temper V is an absolute top flight MC cartridge which holds its own against anything out there today.

The Shelter 501 Mk2 was recently re-tipped at Expert Vinyl and that's a very decent MC.

As to the DL103 being so lowly - that's interesting as the guy who makes Zanden amps uses one.

I keep that fora lot of listening because if my 4 and 5 yr old have a bad moment - it's £200 odd to replace - not over £2000...

In my various experiments I find that a great phono sectionis more important than the cartridge. I refuse to go over a certain price for a cartridge because its just a flipping magnet and thin wire - I've seeen Van Den Hul make them at shows - compare it to an equally priced say car/bike/watch an awful lot more skill and man hours go into making those items - but that's my 2 cents worth.

I hope you don't mind but I will email you directly about the AU340 mods.

thanks
I love the total lack of agreement on this forum at times :)

Both the FR64/FR7/SUT and the lightweight MM/modern MC Active stage may always be at loggerheads - my only way to resolve is to hear it.

@chakster the one you mentioned does allow different transformers, but isn't it a case of plugging and unplugging? I don't like to do that as most my tonearm cables have WBT connectors - not only that you should plug and unplug continuously.
Whilst a bit 'off-topic' everyone has a DL103 - they can provide a benchmark.
Does everyone have a Koetsu Redwood? A Shelter? a Lyra Titan? Let alone a Shun Mook..how does a person compare and track changes in a system? With a benchmark. 
I'm desperate to find what really floats my boat once and for all and want to try the Denon in a few arm/cart combos and plinths - why? it's a hobby - it's fun - it's popcorn for my mind and allows me also to banter with guys/gals like you...


Hi @rauliruegas  - emailed u last night.

Like i said the 103 is a good workaday cartridge - it's very well made for the price. In addition they have good consistency - anyway the thread is about step-ups

I've never tried a step-up and thought I'd try one whilst being able to also do arm multiple mounts - 'killing 2 birds with one stone' so to speak.

I recall once saying to someone that my Shelter 501 with a Nordost cable was far superior to my Tansfiguration with a TCI cable. Thankfully both my phono stages are active (though one can switch to MM).

It's tempting and very costly this hi-fi habit with as many opinions as there are components.

I am taking your tip and seeking out a Denon AU 340.

@chakster and @nandric 

I am not going to get a single input step up transformer. I have what one will call a 'bijou' room so multi inputs are the 'way to go' for me. 

In my 'nearfield' set up I am being drawn more and more to a warmer tonal palette than ever before. I make no apologies for it and do not want to be a 'slave to neutrality' - that said a thick syrupy sound - yuck:)

@rauliruegas I am also exploring a Manley Skipjack or other switching device. 
I just want to know, in part, why so many swear by SUTs
@rauliruegas 
My other option is a further phono stage with multiple inputs - my big problem is that I do not want a sideways or backwards manoeuvre given that both the phono stages I have are very good already...
