Herron or ?

If you can wait for a new one to be built or can find a used Don Sachs preamp, just go for it — and it does use your desired 6sn7 tubes. I don’t think the LTA will give you what you’re looking for.

Thanks for the info

So you would rather listen to distorted sound rather than clean sound?

I have never found Herron equipment to sound lean or dry and I’ve been using ALL Herron equipment for over 20 years. It sounds just like the signal that is fed into it.

Maybe you have other equipment with a very slightly elevated upper midrange that is causing that lean / dry sound.

I think my previous preamp was more colored and i got used to that sound

Stock Herron tubes may sound a bit dry in some systems.

Simple tube rolling can get you what you are seeking.
