Desire to try tubes

So I am new to this have no audio contacts, and low budget it seems based on reading forum. I inherited my brothers Heresy I’s (and LP /CD collection) two years ago and started my journey. First bought a Rega P3 and Rega Fono stage running with existing 20 yo Denon 5.1. Then upgraded the Hereseys from Crites with crossovers and new tweeters (46 yo units). Months later after research and savings bought Stellar GCD and Stellar S 300 amp along with Syzygy SLF 870 sub from Underwoodwally. Nice! Next Marantz 6006 CD as transport and Underwood Emerald Physics and Core Power gold power cords and speaker cables. As able Audio Quest entry connects for all. Each move improved sound. Added a Bluesound node 2i as well only listening to Pandora though. I have no reference to options as I’ve only owned Hereseys and never heard a tube amp in a home and am very curious if a tube pre-amp would be a big plus? If I tried one could muster up to 5k. Just looking for the best sound quality I can afford.
Room is 14.6 x 14.10 x sloped ceiling 8-13’ with 5’ flat section at 13.
Whatever you do, OP, don’t expect to be "one and done." No matter what people tell you, even the "best" systems eventually move on to something better. Even the most confident audiophiles eventually replace their "ultimate speakers" with better ones, same with amps, etc.

Oh, and by the way, Raven has a pretty amazing 45 day trial period while Supratek, which I’ve read great things about, is shipping from Australia. [From their site: "Most product is made to order, a deposit is required and balance on completion . Completion is typically 4-8 weeks, depending on demand. Freight is typically $US 200 to USA, EUROPE, ASIA , $AUD 150-200 within Australia."]

Other names to just toss around which were on my shortlist: Erhard Audio, Herron, Don Sachs, deHavilland, Quicksilver (which I own), VAC.
I had a TWO real bad experiences from the folks down under.. the problem, BOTH companies didn’t give a hoot if they got bad reviews or not.. AND there was NO legal recourse. NONE... Unless you’re a lawyer and can practice law in Australia. NO THANKS!

The travel and transportation cost, tack on a HEAFTY price, alone... 10-15 %.

Our domestic products, 1% for import cost, at the most.. AND you can fly to their doorstep and complain.. You can’t with Australian products. Again there is NO recourse anyways...Better luck dealing with the Chinese, really!, Hate to say it..

There are three products I’m going to try before I quit. Raven is one.

One (ONLY ONE) if I can ever afford it (rich uncle thing). TOP TOP TOP of the line Mcintosh gear. Speakers back to the wall sockets their hardwired into.

Cary Audio, SPL-05, all the WAB, and a pair of TOP TOP TOP, OTL monoblocks (RE) in Jaguar burgundy RED.

My current speakers collection, and unfinished collection will last me 5 lifetimes...

Thank you very much... MY wish list fellas... 250-300,000. aught to cover the Mac stuff... :-) No I’m not a Mac Speaker fan, I don’t think I am anyways. Haven’t heard a ton of them.. Where you gonna listen to them "A Show"..??

Big Plus 1 for Raven..dollar wise in the long run...

I want to hear a 30 watter on the new Planars from GRS.
In 2 month I'll be close.. No paint but I'll have working Bookshelf/planars, Kmini, KMaxy speakers. :-)

Time to feed the chickens... Come on Dog....

Pathos Classic One MkIII.

Hybrid Integrated, tube preamp section and SS  Amp 130 glorious amps @ 4 ohms. 
Tried the Raven Blackhawk and  it was not to be.

Raven makes great cables and speakers though I own all their cables and the CeLest towers.

@millercarbon how much is Raven paying you?

considering my experience with the Blackhawk must be a lot.
