Feeding 11.2V signal to amp instead of "normal" 4.6V

[kohmelo]

I have iFi Pro iDSD DAC that is capable of outputting either fixed 4.6V signal or 11.2V for studio use (as iFi calls it).

Pro iDSD is feeding my Hegel H360 integrated amp via XLR.

 

I was wondering is there any obvious downsides when feeding standard consumer hifi amp with 11.2V signal ?

 

I'm testing 11.2V right now and my first impression is that there is a tad more dynamics in low frequencies, but mid/high frequencies lose some resolution compared to 4.6V signal.

I need more listening, but probably I'll go back feeding my amp with the usual 4.6V signal.

 

Just decided to test it out of interest because convolution filters can attenuate the signal level a lot, and therefor create large sound level differences between sources where convolution is not used. Using 11.2V output, these differences would not be an issue. There is obviously other ways to compensate this difference...

 

Edit. It's not really resolution that is lost. I can't really put my finger what changed in higher frequencies, but for example cymbals sound little bit too "metallic" to my ears.

That of course is a strange thing to say about metallic instrument
