Tubes Asylum Questions about tubes and gear that glows. FAQ |
|
I did try posting this elsewhere but the topic only took off in various directions.
I was toying with the idea of building a DIY impedance buffer/passive type preamp. Just a fun project and nothing serious to replace gear - just fun.
https://www.passdiy.com/project/preamplifiers/b1-buffer-preamp
So here's two questions for the engineer types and those that know FAR more than I do.
I understand the source is the limiting factor. But I'm a tad fuzzy on the potential of preamps gain vs. just a straight signal from the source.
If your source goes through a tubed preamp can the signal in any way have added dynamics. Not only the added gain and buffering of a normal preamp. More actual punch, dynamics, detail, etc.... Can a preamp with gain bring more out, or just loose a tiny bit in the gain process?
With today's sources is a tubed preamp really even needed? Or can it just be replaced with a buffer going basically "passive" directly into a tubed amp?
