Preamps - Active, passive...???


I have seen a number of comments in magazines as well as on-line about preamps as an "unnecessary evil", (my words).

There are products such as Volume Controls and Passive Preamps that are supposedly designed to be as simple as possible; thereby changes to the signal are to be minimal. My question is, "Why then would you buy an active preamp, IF these "simplistic" devices are "better""?

Let me state that I am not ridiculing anyone for there purchases. I am in a state a flux in my stereo and the preamp department leaves me scratching my head. Such as, is something simple, such as a Plactte passive the way to go or a highly rated active preamp.

Thanks in advance for your comments.

I was on a search for a new preamp to replace a veiled and closed-in sounding Rotel RC995 and tried the CJ PV14 (tubie and slightly rolled off), Krell KRC-3 (dynamic yet slightly grainy and expensive), Linn Kollector (worse than the Rotel, wooly and fatiguing), Musical Fidelity A3cr (fairly transparent, a little bass bloom) and Levinson 380 (bright, grainy and expensive). Finally I tried the Placette Passive Line Stage and it was the only thing that didn't muck up the sound in some way. Some of the other preamps are quite good, like the MF A3cr, but all I was looking for was something that was sonically transparent (smooth extended highs, clean natural mids and deep powerful bass) to switch sources and change volume. This might not work in all setups, ie. 20ft interconnects to your amp, but if your ics are under 2m and your components can drive your amp louder than you'd ever listen, why not go with a quality passive?
Never used a passive preamp, but tried my Monarchy DAC, which, says the manufacturer, was designed for direct-to-power amp, straight into my Meitner STR-55 driving 93 dB Tannoys and quickly switched back to my active preamp. The system had enough volume without using the preamp, but as others have observed, bass was flabby and muddy (if loud) and dynamics severely compromised. Has anyone tried the Meitner Bidat direct-to-power amp? Regards, Joel Tatelman
...Dr joe made a good point for passive preamp lovers:
It is true that you can compromise at high volumes in details and dynamics. Depending on your speakers, it can be any part of sound bandwidth especially bass.
Since I do not turn on high volumes, I realy enjoy the passive preamp's transparency.
The best preamp is no preamp. I am useing Wadia 16i directly connect to Classe CA400 to drive Eggleston Andra speakers. It is very transparent. Less is more.
I tried to insert a very good preamp BAT VK50SE in my system, it didn't increase the dynamic, which proof to me that less is more! Also please remember that additional gear in the music loop only will degrade not improve the sonic quality!
If you have an excellent digital source, excellent cables, an excellent amp, and want the convenience of remote control, you owe it to yourself to try the Placette Passive Linestage. It is absolutely phenomenal, with the above caveats. No kidding.
