Balanced to SE to Balanced Again?

Hi all,

Would it make sense to connect a DAC’s balanced output to a balanced-to-unbalanced (1:1 conversion) transformer, then route that to a SE preamp input, then run the preamp output to another unbalanced-to-balanced (1:1 conversion) transformer, then route that ’balanced’ connection to the balanced input of a power amplifier?

I have a true differential balanced DAC, SE preamp, and true differential balanced power amp, and was wondering if I could still use all of these components with transformers between them... or if I need to spend more money upgrading to a fully balanced preamp.

Would this series of conversions destroy any point in running differential balanced connections in the first place, regarding sound characteristics such as detail retrieval, or microdynamics, soundstage/instrument placement/imaging? Would there be issues with things like phase?

Thanks!

Using two outboard transformers will affect sonics in some manner. These extra devices will not provide the transparency of a direct cable run. It would also entail using extra cables and consideration of impedance values.

I have used a Jensen transformer successfully, but there was a slight change in sonics. A low impedance cable must be used at the input to a transformer.

If your DAC has a preamp section you could go balanced directly to the amp.
