Serious Passive Preamp question


I have a Audio Research LS7 Line stage preamp and someone wants to trade me my AR LS7 for a serious passive preamp
Is anyone familiar with this company ?... I was told it retails for $2200.
 My  Amps are Class D wyred 4 sound mono blocks.
Opinions please.

  If your system is passive friendly, an active preamp is only going to color the sound further.  Now if this coloration is pleasant to you, you are golden. But I am of the mind that you are fixing something upstream that you don't like.

I don’t believe ANY active preamp can better a "properly used" passive for transparency, dynamics, uncoloured sound and extension in both the highs and lows. Unless you need to purposely colour the sound with the coloration's that all active preamps give.

Just read what  rob67  with friends and family said in a 4 way shootout in a very expensive hiend system, when comparing a passive pre to these three active preamps.

Even though passives are my game, I don’t believe ANY active preamp can better a "properly used" passive for transparency, dynamics, uncoloured sound and extension in both the highs and lows.

Saying that though your AR LS7 is "worth" far more to sell than any passive is (except for one) worth, regardless of which one.

The one I’m talking about is the $20k D’artZeel NHB-18NS as it also uses the same LED/LDR passive system as the one I make does.
