Budget Tube Amp (newbie)

I also love Decware, but I have only owned (still own 2) of their low WPC amps and those low WPC amps wouldn't drive those speakers as well as PrimaLuna in my experience.  I know they make some higher power ones.

Number one..resign yourself to a tube integrated (keep it simple) and be ensured complete compatibility vs going the amp-preamp experimentation route where negotiating the learning curve could become costly!
for your Advents I would pass on the Rogue ..why shoot a mouse with an elephant gun?
I suggest finding a clean used Line Magnetic  EL-34 based integrated and its in your budget.

Another Jolida recommendation. I just bought a Jolida SJ-302a a couple of weeks ago. It's integrated,  puts out 50 wpc, and was only $450 from my local dealer, who had taken it in from an estate sale. The drawbacks - it's not auto biased, but that's easy to do, it's about 25 years old, and it has no remote,  but it sounds wonderful,  and cost less than $500 including tax. I noticed a very obvious difference with my similar vintage Chapman t7 speakers moving to this amp from solid state.

Ok, in response to "bdp24", I appreciate you being brutally honest! So, yes, in some respects I DO want to see what all the fuss is about.  Having known a couple of friends who had the old Dynaco ST70's back in the day, along with the Macs, I was really impressed by the sound.  However, not having the funds to go that way, I went the way of SS amps: I've owned the old Scott, Marantz, Pioneer, and Yamaha. The CR 1020 is the current SS amp I currently own. I currently own a pair of Bose 601bookshlef (4 ohms), a pair of Large Advents (8 ohms), and a pair of Fisher STV-880 (8 ohms) floor standing speakers. All of which have been re-coned and, in the case of the Advents, the cross-overs and caps redone.  As some of you "old guys" may know, the older SS amps could run (2) sets of speakers at the same time. In that regard, the Fishers complement the Large Advents. (maybe, the other speakers I have will "play" better with a tube amp?) Thoughts??
That all being said, it still lacks the "warmth" of what I remember tubes bring into the picture.  So, thanks to so many of you who have offered your time and knowledge, I am attempting to learn "the way of the tubes". lol  Now, because of you all, I realize that the ST 70 is not the way to go for me as there are better models out there even in the "budget" realm.
So, for those of you who have "been there-done that", I welcome the comments.  bdp24 also mentioned that maybe a tube pre-amp might work with my current SS Yamaha??  Thoughts??
Now, I know I am going to probably open a big can of worms on the next subject. But, once again, I am totally ignorant about the subject:
" interconnects"  I've read where people are spending major $$ on them. "Back in the day", the only "interconnects" I knew about were RCA cables. So, now at 65, I don't think I need another SS amp.And, I'm willing to humble myself and learn. But, maybe "with a little help from my friends", I can explore this avenue without, (as clhs04 stated) " ensure complete compatibility vs going the amp-pre-amp experimentation route where negotiating the learning curve could become costly!"  Again, many thanks!
Best regards,
