Step Up Transformer recommendations for a Denon DL-103

Here is an internal shot of my SUT.

Thanks.
I was not able to do that on my phone.

Does it look “normal” for a SUT with Haufe transformers?
I can’t see any manufacturers marks without taking it apart further.

It sounds seeet enough though with my DL-103C1

I have found that the choice of interconnect cables SUT to preamp makes a significant change to the sound quality. Currently using Rothwell The River to suit my need. Silvered OFC copper also suits . Electrical values seem to be difficult to equate to actual results . Worth trying all types . Lower impedances tend to dull the sound which may present as increased bass. Higher resistances make for a more dynamic bright sound ( my preference since my speakers can make bass from nothing much) . Not at all sure that these comments are generally valid but it's my experience ( Hana SL)

Yes, the cable between the transformer and the phonostage can make a difference, though I would expect it to be subtle rather than massive. The capacitance of the cable can have an effect on the high frequency/transient performance of the transformer, particularly if there's no optimised load network on the secondary winding. Also, shielded cable is a must if you want to avoid hum problems.

Hi Kevin,

Pity you didn't PM me about this, as for most of the festive period I've been 'off grid' on hi-fi matters, concentrating instead on eating, drinking and entertaining guests!

Had you done so, I could've have given you some useful advice... Anyway, have you got the cables for your SUT the wrong way round? It looks like the polarity of the incoming black and red cables are reversed on the output?

To test for this, so that channels aren't mixed up, use a test disc or some music where you know what instruments should be on which channels, to see that all is ok.

Marco.

I realised that I had made a mistake, and it has since be corrected.
Having never heard a SUT, I fancied trying one and this “vintage” Haufe seems to be working well.

I’ll be sending my KIN back to Mr Firebottle soon, so this may well become surplus to requirements.

No worries... For a different 'flavour', you may want to try a good head amp at some point, and compare it against your SUT. In the meantime though, enjoy

The transformers don't look like the Haufe transformers I have. The ones I have, and others that I have seen, have cylindrical metal housings.

But if you bought your SUT from Haufe, then one must assume they are Haufe transformers.

They look a bit like these: https://www.ebay.com/itm/Haufe-Outpu...p2047675.l2557
