Quad Tube Rolling

Okay, this may sound like a dumb question for smart audiophiles but i am still earning my wings in this fine hobby. In short, I am only too happy to defer to this knowledgeable forum and would greatly appreciate any input.  My question is, will it make a noticeable sonic difference if i changed the input tubes on Schiit Freya+. I recently changed the stock input tubes from 6SN7GTB (Russian) to the Sylvania 5692 red base (1950) and found them to be a welcomed improvement and they are still just breaking in. So, it makes sense to do the same with the input but that is a $175.00 decision so i am needing some big brother advise... What say ye?

If your phono stage and preamp allow balanced connections you should 'em. Otherwise single ended works fine.

Speaking from actual experience, I’ve rolled the "quad" of tubes in my original version Freya often to get to what I prefer, and tried mixing the input and "left side" tubes all to interesting effect. I wound up preferring NOS GEs and Sylvanias, and am currently using 4 matched GEs. Note that cleaning the contacts will help make the system work as it should, but Millercarbon’s condescending claims of "10 times better" with a ridiculous fuse swap is just another opportunity for him to embarrassingly grab at another hyperbolic SR promotion. The fuse swap can and will do nothing except cost you 175 bucks. Tubes are an active component with an obvious effect on the tone, fuses are not an active component as they’re fuses, and any working fuse (like the one you already have) just sits there waiting to blow when needed, not unlike
