Solid state amp/Tube Preamp. Possible?

Ive run tube preamps and solid state amps in different combos for years..Never gave the matching any thought and never had any issues..IMO, the tech info of matching may have its credits but in any system I put together it never was...

Tubed preamp and solid state amps make beautiful music for me.

I've used an Atma-Spere MP-1 MK III and a Lamm L2 Reference (not fully tubed), and a Lamm LL2 Deluxe with solid state amps with excellent results. All of these preamps have low output impedances (below 200 ohms for the Lamms, and I believe 600 ohms for the Atma-Sphere).

I tried an ARC Ref 3 with solid state amps (Pass Labs) with so-so results.

I'll keep the measurement specs concept in my back pocket for future reference.

TVAD, I wasn't disputing your point and certainly not John Atkinsons measurements regarding impedance. In my experience, I've have never had a problem matching components. Nowhere in my post did I imply that you should ignore matching the impedance. The main point I was hooping to convey is that I believe it is better to go for a tubed preamp with solid state amp than to go the other way using a solid state preamp with a tubed amp, which I think was my attempt at providing Deanna with my experience and my opinion pertaining to her question. I thought that was pretty clear in my post, if not, hopefully this is clearer.

Got it. Thanks for clearing that up for me.
