Tube virgin looking for tube amp under $3k

I’ve never owned any tube amps or preamps and since I’ve got 95dB efficient speakers I thought why the heck not? And wow! What a rabbit hole I’ve gone down In the last week or so and my head is really spinning. For just about every amp or amp/preamp combo there’s someone who loves it and someone who says don’t bother. And then the more I dig, the more brands I find.

I’ve read about these products recently:

— Erhard Audio integrated amp 
—The various iterations of the ST-70 (Van Alstein, Bob Latino, Will Vincent, etc.)
—Music Reference RM10
—Cary (out of budget except used)
—Raven (at max budget for integrated)
—Dennis Had (hard to buy/find)
—Quicksilver Mid mono (need preamp)
—Decware (too long a wait for me at the moment but maybe one day)
—Rogue Audio Cronus Magnum III (at max budget and do I really need 100WPC with my speakers in a small room?)

And probably a few others I’ve forgotten about already. 

I have to say that the Bob Latino ST-70 speaks to me for the price of entry (about $1400) and the fact that I could get away without a preamp and only use a passive input selector. That said, would an ST-70 be the best choice or only the cheapest? 

Any ideas for a tube newb who doesn’t have a stockpile of tubes to roll in and out of an amp?

+8 for Primaluna and i agree with the reasons previously described to consider it.

 Here’s a used Dialogue HP Integrated for $3,600 https://www.usaudiomart.com/details/649628037-primaluna-dialogue-premium-hp-integrated/

I bought mine direct from their US distributor Upscale audio after going there (So. Cal.) from my home in Alabama to audition it with speakers similar to my 90 dB sensitivity Goldenear speakers.  With your super efficient speakers, you will not come near straining the amp (I rarely get above 9:00 volume with my less efficient speakers) and may never have to replace the tubes. 
I talked with the Upscale salesman who found a B-stock had come in recently from the manufacturer. It had a small blemish in the automotive quality paint job on the back of the amp that nobody will ever see and obviously has no effect on its sound quality.  I was able to buy it for close to the price of the used one shown above.

Decware- best in terms of sound quality, Bob Latino good choice in terms of sound per dollar .
don’t overlook Transcendent Sound if you’re into kit stuff.

In my office setup, I have Omega Compact Alnico monitors, which I was driving with a Cary CAD300SEI that I purchased 3 or so years ago, until I decided to move it to my main setup a couple years ago.  This is a SET (Single Ended Triode) integrated amp with 300B output tubes.  This was a wonderful combination, and I recommend you investigate a SET amp for your Omegas.  The 15 Watts is plenty of power for the Omegas, especially since they have a very benign impedance response.  The midrange is wonderful resulting in absolutely mesmerizing vocals, and contrary to popular wisdom I've never felt bass was at all lacking.

Robert Hartley of Stereophile had a very favorable review of the CAD300SEI back in 1995 (https://www.stereophile.com/integratedamps/398/index.html), and Cary made several improvements over the years.  While it might not be in time for your decision, I'll also be listing mine in the next month or so as I've decided to go a different direction for my main speakers (92 dB sensitivity, but a difficult load with dips to 2.53 Ohms).  I had all the upgrades Cary offers as well as having them put in a pre-out RCA connector for each channel in case I wanted to add subs, and also put in NOS tubes for the driver and output tubes though the 300B power tubes are the originals.
