Passive attenuator/ preamp

I've used a passive pre amp Audio Synthesis from England for quite a while. If all the factors are in place ie: short cable length, capacitance and resistance of cables are conducive to a passive unit, and the source produces a strong enough signal then the sound is pristine and clear. however may lack dynamics . Good luck Harvey

I have tried various passive devices. The sound is always cleaner. However, the interaction of DAC, interconnects and Power amp is much more noticable and could end up with a less pleasing over all sound. You have to try it.

I have a welborne labs passive preamp and it kills my active preamp. The best thing about welbones is you can build them your self so you can use your favorate wire in the singnal path and parts quality is second to none.

If your really thinking of going passive you must go to Rick Schultz's web site tweakaudio.com he is the best there is in the biz for passive very well thought out units.
