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.

I suggest trying the Rogue series from $800 to $4,000 for easy use and it is not necessary to be an electrical engineer to use.  These are integrated amps and I also like the ones that have a tube 'pre-amp' and non-tube full amp.  These are the least fussy and give the richness of tubes without the many other hassels.  I have a Peachtree X-1 hybred integrated amp that is my favorite at 440 watts per channel.  I also have a nice Vincent 701 pre-amp for my turntable that features 1 12AU7 tube that really pumps up the vinyl that is further tubed by the 2 tubes in the amplifier 'pre-amp'.  This amp is not longer available new. 
 
Atma-sphere is built in Minnesota and run by really great people to work with and the producer of one of the best series built in the U.S.  A wide range of choices and they build to your specs and needs.  These guys will even send you a unit to try out before you purchase.  This is hard to beat.  I think they know once you have heard their amps you will park it in their lot.  If you talk with Ralph he will make it easy.  See the opening video on their web site.  My next amp will be from Atma-sphere where they will build a capable fully tubed amp with a tubed phono stage preamp built in for under $2,500.  You should at least 'test drive' one of their products.

You said what I have been saying about @millercarbon for a while. He is an opinionated shill and if you cross him you are a dope. He’s the dope. All he does is post. I don’t think he ever does anything else. Watch his post count, it goes up significantly every week. He posts just to be a dippy tool. I’ve got your back @skypunk.
@rcronk I hear you on trying Atma-shere. I’ve been keeping an eye on his stuff for a while. Someday I’ll be able to try it. Got to get some speakers that match up with lower power amps first.

I did the Rogue trip with their Stereo 100. It didn’t match up with my speakers very well and had terrible distortion. I tried to get relief from the dealer and Rogue with no success. Ended up trading it for a non-American brand that sounds great. Only had it for two months.
If you still use the Heresies, and they are still 96db sensitive after your mods, and you want the “tube” sound, you need single ended triode amps. Buy used, or buy a kit, to save money (Bottlehead may be a good place for a kit) but nothing touches SETs for glorious sound. Speakers need to be efficient, the Heresies are, but nothing else can match that sound. I built my first one 20 years ago, it still works, and I have never looked back.
