With my FR-7fz and previous FR-7f i've been using this toroidal silver sut, they are superb for all LOMC cartridges, 3 inserts available for different impedance.
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

I do have XF-1 L which is better than 4 or 5. Check pricing and use translator. XF-1 L works with LOMC up to 3 ohms. I do use it with Ikeda canitleverless which is 3 ohms. If you want to get this one some day: https://audio-heritage.jp/FIDELITYRESEARCH/etc/fr-7f.html and to use it with dedicated step up it will be XF-1 L or if you want more universal unit buy FIDELITY RESEARCH XG-7 |
I have an XG-5 in my second system, also the universal type with 3 positions and one 'step down' from XG-7. It sounds really nice, but not on the same level as my other two dedicated step ups, Entré ET-200 (copper wire) and Ortofon T-3000 (silver wire), both for MC's in the 2 to 6 ohm range and both with 30dB gain. If you plan on using FR7 or other low impedance cartridges, a dedicated low impedance type is preferable. I have no experience with XF-1L, so don't know how it compares to the ones mentioned above. There also was a silver wire step up from FR. This is quite rare, sought after and expensive. I saw it offered twice in the last 5 years and sold instantly, so it must be very good. BTW: I would advise against using a low impedance step up with Benz LP-S. |
Dear @lohanimal : Ste up transformers are not " rocket science " and does not changed in the last 40+ years. What changed was if are silver coiled or cooper or what ever but the functions stays the same. I owned FR, AT, Denon, Entré and several other SUT's and with out doubt I can recomend to you the Denon AU-340 that I still own along the Denon AU-1000 ( both modified by me. ). You can't go wrong with the 340 that works really good with any vintage or today cartridges: https://audio-heritage.jp/DENON/etc/au-340.html https://www.vinylengine.com/library/denon/au-340.shtml Please take a look to the Denon frequency range against the top FR or any FR SUT, Denon outperforms any of them and this spec tell us a lot about the quality of those transformer designed by Denon. Regards and enjoy the MUSIC NOT DISTORTIONS, R. |
