Amp/Preamp Asylum Looking for a new Amp or Preamp? If you're after tubes, post over here. |

I am a very happy owner of a Musical Fidelity Nuvista Power 300, Chord Electronics Blu/QDB76, Sonus Faber Electa Amator II, Tannoy ST100 Super Tweeter HiFi system all wired with Townshend Audio DCT cables and interconnects.
I just added a Musica Fidelity X-AS100 power amplifier so I have Bi-Amplified my Electa Amator II's, the NuVista on the bass and X-AS100 on the treble.
I have noticed a surprising increase in bass definition, however on some tracks I am getting a more forward high frequency balance, the highs sounding less defined and more present. I have read that valves and transistors a not a good match because of response, damping factor and gain matching.
Would a valve based power amplifier for the treble smooth out the forward balance, which valve amplifiers would you recommend to match the NuVista?
Regards
David
