Passive preamp


What is passive preamp and how to connect them

I have a passive that I ran in my system for a long time and really enjoy it. However right now I am enjoying the distortion that a tube  pre has to offer. If you have the gain,a passive is the next best thing to straight wire.

Hit the nail on the head, it’s the most transparent/dynamic/uncolored way of getting the sources signal to the poweramp/s

Quote from Nelson Pass

Nelson Pass,

We’ve got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more.

Think of it this way: If you are running your volume control down around 9 o’clock, you are actually throwing away signal level so that a subsequent gain stage can make it back up.

Routinely DIYers opt to make themselves a “passive preamp” - just an input selector and a volume control.

What could be better? Hardly any noise or distortion added by these simple passive parts. No feedback, no worrying about what type of capacitors – just musical perfection.

And yet there are guys out there who don’t care for the result. “It sucks the life out of the music”, is a commonly heard refrain (really - I’m being serious here!). Maybe they are reacting psychologically to the need to turn the volume control up compared to an active preamp.

I have sent you an email asking for pricing info for the Lightspeed Attenuator. A friend and I will test it seeing as though the reviews have been rave. Excellent work, George. Incredibly excellent work. However, when I am having a party (I have them quite often) and would like to change among sources, it would be great to have a passive tube preamp that can accomplish this. I have read about the Schiit Freya among others. Would you make any recommendations? Thanks so much for your time.
I own the original version of the Schiit Freya and it can switch immediately (the newer Freya + "improved" version shuts off the tubes when one of the other outputs, passive or FET, are utilized...so you have to wait for the tubes to warm up if switched) between the 3 modes...passive sounds fine but the tube mode sounds better for my tastes. Just more "there" there. Switching among modes keeps the tubes honest since if you notice a degradation of some sort with the tube mode you simply replace the tubes.

Sent with mandatory propaganda attachments.  And yes as Wolf points out the Freya is a great universal unit, I have recommended it many a time here on Audiogon.
As for a passive though the transparency/dynamics of the Lightspeed has no equal, as there are no contacts  in the signal path in the circuit.
