NuPrime

 

  8 

 

Vast soundstage 

 

Wide, lightning-fast dynamics 

 

Ultra-low distortion and noise 

 

Music emerges from a pristine background, with delicate details and nuances intact 

 
In summary, NuPrime’s sonic character stands well apart from – and indeed above – the soft, cushy sound 
we often associate with most tubed amplification or the dry, clinically edgy sound we often associate with 
solid-state and switching technology. Rarely does an amp achieve an ideal balance of richly textured timbres 
and  harmonics,  bottom-end  authority,  startling  dynamics,  exquisite  low-level  detail,  and  a  fully  revealed, 
fully dimensional soundstage against a backdrop of mile-deep silence.
