beginner seperate system

i think Im good with my nad amps bridged for ss...the website says over 1200 watts bridged....https://nadelectronics.com/product/c-275bee-stereo-power-amplifier/
but I do want to try tubes.  i see some great suggestions, just wrestling with my budget.  I dont know/understand alot of the terminology or names in tubes...so Im googling all the suggestions.  I appreciate them as I am learning as I go.  all good stuff.

thanks, I seen an ad for that crimson tube amp...think in same mag saw a tube 50% off which is scarey to think why.  gonna get driven down to local dealer in next week or so, but not sure if they have tube amps...they just carry the mcintosh, sim moon, avr stuff i think.  can you mail order with easy returns from some tube amp makers?

will a tube preamp give me the tubey sound?

I was gonna ask about shiit audio as its american made and priced in my range...also seen some chinese tube amps on amazon...Im not looking to play tubes very loud well I guess if I like em alot they will be played loud :)

I dont plan on changing away from my current setup.  but would like to add a tubes setup.  not sure whether a totally different path or adding a tube into current setup.  was thinking if I could just add into mix an integrated tube...what would easiest way be to add tubes?  avr preouts to bridged nads to speakers currently....

Jolida and shiit gonna check out.  might go to local brick mortar and check them out.  broke in the new year with too much partying and not so much sleep...and the world is punishing me,,,,lol.

primaluna always has a lot of buzz around their amps...but always see them for sale on used market...decisions...think Im gonna make a trip to listenup this weekend or next week and listen to their sales force.  bad thing about going to listenup is seeing the new revel be and kanta 2/3 speakers...might put the tubes on back burner and get new speakers lol.  and throw budget out window in process...
maybe just make some phone calls :)

and then I see some cheaper than dirt ideas on massdrop....https://www.massdrop.com/buy/fx-audio-tube-p1-amplifier?utm_placement=2&referer=236SQC&mode=.......is this even worth the 100 bucks?

this jolida looks like what I might be looking for...https://www.musicdirect.com/integrated-amp/jolida-fx10-integrated-tube-ampdecisions, decisions

when I go visit my local brick mortar I will listen to some mcintosh tube setups with my focal aria 948.  these are out of my price range but will give me a decent idea plus listen to what dealer thinks...I have a chinese tube headphone amp and thus has me curious to what tubes can do with my focals.  of course everytime I visit dealer I have a dream of taking focal sopra 3's home...a dream.  the reviews on jolida seem to have some qc issues and/or bad experiences.  appreciate all the comments...will be researching until I pull the trigger.  gotta do my taxes before I buy tho.  been having to write checks last few years to govt so gotta look a lil closer this year...been slacking lately on taxes :(
