Preamps. Do we really need them?


I've been shopping for a new preamp lately, reading the forums, etc. If I have only one source, a DAC into which all my digital components feed into, do I really need a preamp and not just a volume control. After all, that's all I really need from a preamp. I've heard about passive rigs that just control volume, or attenuate it. I understand that you lose some volume if, the source's output isn't enough to drive the amp staight. I'm willing to make that sacrifice.

It is my contention that if you have:

1. A source with low output impedance, most made today do
2. A power amp with a high input impedance, many do, especially tube amps
3. cables with low reactance that aren't too long from pre to power amp, I use 1/2 meter Cardas Neutral Reference

there is no way an active stage can do anything but degrade the signal.

I have used and I am using a passive preamp with wonderful results. Great dynamics, superb resolution, plenty of extension on both ends of the frequency spectrum, and I saved a bunch of money not having to buy an expensive preamp.

As suggested, buy a good used unit and try it.
I have owned a number of preamps, both active and passive. I’ve finally settled on a passive from Placette. It is mercilessly accurate and transparent. It comes with a full money back guaranty if you don’t like it.
