Preamps can color sound considerably. Surprising?


Had the pleasure of listening to 4 hi end preamplifiers this weekend. And each preamp sounded very nice. But they were different. Each preamplifier has different circuitry and within the frequency spectrum there was more vibrancy in some areas versus other areas. Amplifiers are the same way.

It takes a while to appreciate sound differences between preamplifiers. And then you got the issue of Breakin which further changes the color.

clearly designers are playing around with all the internal circuitry in a manner that hopefully will be appealing. Clearly, these units do not get out of the way when it comes to moving a signal through the box.

I think solid state is more susceptible to coloring versus tubes. Tubes color sound as well.

It's all about marketing different ways to color Music. This isn't necessarily bad but it's never really talked about this way.

This is exactly why I eschew active preamps. I have owned quite a few well respected ones, the last being a Don Sachs which was very good. But when compared to a good passive, it's just no contest. As long as you have reasonably efficient speakers, robust source components and an amplifier that is easily driven, there is no need for gain that you are effectively going to throw away.

The only "authentic" sound is what the guys in the studio heard.

On particular headphones or monitor speakers, with their amplification, after the mics, mixing board adjustments and additions, and all the intentions for that mix to be played over other kinds of speakers (car, radio, etc.).

It's color all the way down.

Those engineers operating the studio gear are putting that sacred "absolute sound" through miles of wires, pan pots, addled brains, unclean tape heads, unclean bald heads, digital manipulation, badly tuned pianos, and personal tastes just like the home hifi geek. The only way around it is to hire musicians to form a circle around you while you lie on the floor after recently having cleaned your ears. Preamps sound however the designer wanted them to so it's up to you to decide what sonic manipulation you prefer. If you're lucky you can enjoy music...or spoken word...or dump trucks backing up...lucky you.

+1, An effective dose of reality nicely summarized.

With every component of every preamp being different of course they will all sound different.  Just as tube rolling changes the sound so do capacitor’s, transformers, resistors etc.   And today, SS preamps can sound so amazing close to tubes it’s scary!

I’m not sure if this matters but if you think about it, a typical preamp amplifies millionth to volts so a thousand or so times but an amp just takes volts and amplifies less than 100. The pre amp does more “work” & is more susceptible to distortion & extraneous noises because the signal they deal with is so much smaller.
