Step Up Transformer

Dear @edgewear  : I think that the " trouble " culd be that till today maybe you do not experienced listen sessions trhough an excellent designed phonolinepreamp like latest Dartzeel, FMA, CH, Moon and the like. No, Boulder is not in that league is good but not excellent, overall my unit belongs to that league. Till you live that experience you will follow thinking in the same way. No, it's not only about " numbers " but something that even a non-audiopile can dicern easily about and I already posted that I'm not against per sé to SUT's that I not only own but time to time have lisen sessions with , good sessions but the active high gain is superior and I have to say that with the AU-1000 not for a wide margin but superior.

It is looking like the suggestion from one contributor and maybe indirectly others, for the action required to take a Step Forward that is noticeable and a betterment, to using a SUT, if the 'off the shelf' option is considered. Requires that to get the best of the experience without a SUT, monies are needed to be parted with, that can be up to a five figure sum.

The most expensive Commercial Product Phon' I have received a demo' off, is offered with a £10K retail price. This is a Phon' I have been in front of whilst in use on many occasions and it is a Phon' that has thoroughly impressed me. It is also a Phon' I am able to live without, as I have Phon's that are not of this Value, that offer a impression that is just as satisfying.

Bear in mind, both Phon's owned by myself, are very close in their base values to the £10K, when the electronics are being priced. I also believe the designs between the three Phon's are not too distant and there is a shared trait that can be discovered between the Phon's.

Five figure sums are not required to purchase a Phon' that can thoroughly impress.

@edgewear : Btw, you could be one of the future owners of the 3180 that will be custom made due that the owner can choose between unit with 2 MC independent stages or one MC stage and one MM stage. In the MC/MM configuration both independent stages are different at the input gain stage due that in the MM we don’t use bipolar devices as in the dedicated MC but a different active input device dedicated to MM. Any one could has the opportunity to to arrive at a little " different " new " enjoyment world " through the 3180.

Anyway, the main issue is to enjoy MUSIC for any one of us.

This ha been a really good discussion. I was thinking of purchasing a SUT from Bobs Devices, simply because I didn’t know where else to look.

Are there any suggestions for an off the shelf step up transformer, one with wide frequency band and low distortion?

thanks. 

Not sure what you're after. Bobs Devices SUTs are certainly "off the shelf", and if you purchase one of their best SUTs, and one that is suitable to both your cartridge and your phono stage, you will probably have wide bandwidth and low distortion.

Pindac, I am not sure you directed a question at me, but if so, as regards voltage vs current, in the case of a SUT, you are aiming to amplify voltage, not current, so the fact that you lose current in proportion to the voltage gain is of no consequence to the downstream voltage driven phono stage.  The advent of current driven phono stages has muddied the water for some, but you'd never want to use a SUT with a current driven phono stage.
