Preamp Noise with High-Efficiency Speakers

I have Avantgarde Duo Classic Speakers, I hear a very audible buzzing noise whenever I insert an analog preamp. If I run my DAC (AMR DP-777) directly into power amp, the noise disappears. I have tried 4 different preamps (tube and SS), 3 different amps, a bunch of RCA and XLR interconnects, the problem persists. I have tried dedicated power line and two power conditioners (with Multi-wave options) and various high-quality power cords, so far nothing works, and I am forced to run DAC-direct into power amp. The buzz is not very loud but certainly audible enough to be annoying. There's no noise running the same equipment and power source into regular speakers, I am pretty sure it's just the Avantgarde (104dB sensitivity). Please share your solution if you have had similar situations. Thanks!

Not apologizing to you at all, just correcting your misinterpritation of Nelson Pass's statement, as you also did with my post.

Cheers George

Roscoeiii and Grannyring,
I know others who patiently tried various passive components in their system based on the predicted advantages. Ultimately they returned to high quality active linestages as they provided a more realistic and natural sound that more closely mimics live instruments and human voice, just as you two discovered.No theory will ever substitute for the personal experience of direct listening with your own ears.Nothing.

Any component that preserves the full tone,harmonics, body, scale and dynamics that are so obvious with live music is closer to the truth.Most listeners 'long term' won`t be happy with a device that`s incapable of maitaining this vital signal information. How the attributes of fuller tone,saturation and dynamic vibrancy can be a "coloration" when their presence is so very obvious with live performances? It would seem the passive(or active in some cases) component is subtractive of the complete audio signal if it doesn`t maintain these mandatory and honest aspects of the music, this is why music has emotional power and involves us.If these nautral and intrinsic features of live music are not lost or diluted then the component is doing its job,be it active or passive.

Bill.
We have a piano in our that sounds beautiful. I attend the local jazz clubs frequently and love them. Any audio component that strips or dilutes that tone,body,weight and dynamics that I hear"always"in live music is a flawed component. If this is voodoo or coloration, I`ll have more please.You tried the Lightspeed "three" times, once would have done it for me.
