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.

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.

"...But when compared to a good passive, it's just no contest..."

I've tried the Creek OBH22, which provides great clarity and resolution - because I wanted to go direct to an amp, but with a volume control with remote.  It did provide greater clarity than my preamps. 

But... what passives do you suggest?  Townshend?  Others? 

I realize this is not focused on passives, and that there are other threads that do - but - just wondered what your experience has been in this regard?  

If you want a better chance of hearing what the audience heard listen to live recordings in a multichannel system. Studio recordings for the most part are sewn together like pieces of a puzzle into a sonic quilt. It isn't the same as a live recording. An audience at a concert isn't listening to "stereo" and are "immersed" instead. If you want to get a good preamp get a multichannel preamp and "immerse" yourself in live concert recordings.

The cleanest sounding preamp to me is my Tortuga Audio LDR, total clarity and measures poorly according to ASR 😎
