Preamp for First Watt F7

Thanks for all of your feedback. I'll check out these different options.

The F7 arrives tomorrow, so I don't have a preamp for it yet. I've got a Freya S downstairs which I'll try for a bit and maybe stick with that if it sounds ok. I use that currently with a 300b integrated for more inputs and volume control (I run it in passive most of the time, buffer mode some times).

I've had an F7 before for a short while which I used with a Freya +. It was an ok combination, it's honestly hard to remember. At the time I was using Zu Soul Superfly speakers which were high efficiency, but not my type of sound. So when I sold the speakers I sold off the whole system more or less.

I'm interested in the Quicksilver, Van Alstine, and also read good reports about the Wyred 4 Sound STP-SE if anyone has experience with that.

I'm looking for a warmer sound signature. I am no longer a critical listener, just want something that sounds good without bright edges. All of the components (Pontus, Tannoy, Firstwatt) lean towards that. The more I am reading up on things the more I'm leaning toward a tubed preamp. I've reached out to Van Alstine to see what they they think about the match up with an F7, will let you know if I go down that route. the 10RB is interesting for sure. The Rogues are also interesting, will message you privately.

Thanks for your feedback. Someone messaged me this article which talks about the synergy of the MicroZotl with the FirstWatt F7. Figured I would share it here. The output impedance I believe is single digit ohms. Worth a shot, I'll probably start here if I can find a used one.
